Description
[0001] The invention relates to an installation for producing a
textile web-shaped material according to the precharacterizing part
of claim 1 and to a method for producing a textile web-shaped
material according to claim 9.
[0002] Installations for producing a textile web-shaped material
are known which comprise at least one device for parallelizing
fibers and at least one transport device for transporting the
textile web-shaped material in transport direction. Further, such
installations preferably comprise consolidating devices for
consolidating the textile web-shaped material. However, for
different textile web-shaped materials, use is made of different
installations comprising different devices. This makes it necessary
e.g. to modify these installations and to exchange various
devices.
[0003] It is an object of the invention to provide an installation
and a method for producing a textile web-shaped material, wherein
said installation and respectively method shall be flexible in
use.
[0004] The invention advantageously provides that at least one
device for flow-through treatment of the textile web-shaped
material with a gaseous medium, at least one device for applying a
binding agent to the textile web-shaped material, and at least one
transport deflection device are provided, wherein said transport
deflection device can deflect the textile web-shaped material
around said device for flow-through treatment and/or around said
device for applying a binding agent.
[0005] This has the advantage that the installation is very
flexible. Thus, the installation can be used as an installation
comprising a device for flow-through treatment of the textile
web-shaped material or, alternatively, as an installation
comprising a device for applying a binding agent, or, by way of a
further alternative, as an installation comprising both said device
for flow-through treatment of the textile web-shaped material and
the device for applying a binding agent. Thus, the installation can
be quickly adapted to the demands.
[0006] The device for flow-through treatment of the textile
web-shaped material can be arranged in transport direction behind
the device for applying a binding agent.
[0007] The at least one transport deflection device can be
adjustable in such a manner that the textile web-shaped material
can be deflected around the device for applying a binding agent and
can be passed through the device for flow-through treatment of the
textile web-shaped material, wherein the device for flow-through
treatment of the textile web-shaped material can be used as a
thermobonding device.
[0008] The at least one transport deflection device can be
adjustable in such a manner that the textile web-shaped material
can be passed both through the device for flow-through treatment
and through the device for applying a binding agent, wherein the
device for flow-through treatment of the textile web-shaped
material can be used as a dryer.
[0009] If the device for flow-through treatment of the textile
web-shaped material is arranged in transport direction behind the
device for applying a binding agent, the device for flow-through
treatment of the textile web-shaped material can be used, on the
one hand, as a thermobonding device if the textile web-shaped
material is guided around the device for applying a binding agent,
and, on the other hand, if the textile web-shaped material is
passed through the device for applying a binding agent, the device
for flow-through treatment of the textile web-shaped material,
which is arranged therebehind, can be used as a dryer.
[0010] A thermobonding device is a device wherein, during the
flow-through treatment e.g. by means of air, the textile web-shaped
material passed through this device will be heated to a temperature
above the melting temperature of individual fibers existing in the
textile web-shaped material, so that the nonwoven will be
consolidated in the process.
[0011] The device for flow-through treatment of the web-shaped
material can comprise at least one deflection device by which the
textile web-shaped material treated by said device can be guided,
for cooling, out of the device or, alternatively, can be deflected
to the device for curing. The textile web-shaped material can be
transported without cooling from the device for flow-through
treatment to the device for curing.
[0012] Between the device for flow-through treatment and the device
for curing, a heating channel can be arranged through which the
web-shaped material can be transported with the aid of the
transport device.
[0013] The device for flow-through treatment can also be arranged
in transport direction before the device for applying a binding
agent, wherein the device for flow-through treatment of the textile
web-shaped material can be used as a thermobonding device.
[0014] If the installation comprises still further consolidation
devices, it can also be provided that both the device for
flow-through treatment and the device for applying a binding agent
can be passed by with the aid of the transport deflection device,
i.e. the textile web-shaped material can be deflected both around
the device for flow-through treatment and around the device for
applying a binding agent.
[0015] Further, the invention advantageously provides a method for
producing a textile web-shaped material comprising the following
method steps: [0016] transporting the textile web-shaped material
through an installation comprising at least one device for
parallelizing fibers, at least one device for flow-through
treatment of the textile web-shaped material, and at least one
device for applying a binding agent, [0017] wherein the textile
web-shaped material can be guided, by at least one transport
deflection device, around the device for flow-through treatment of
the textile web-shaped material and/or the device for applying a
binding agent.
[0018] The textile web-shaped material can be passed through the
device for flow-through treatment of the textile web-shaped
material and can be deflected around the device for applying a
binding agent, wherein the device for flow-through treatment of the
textile web-shaped material is usable and respectively is used as a
thermobonding device.
[0019] The textile web-shaped material can be guided through the
device for applying a binding agent and be guided around the device
for flow-through treatment of the textile web-shaped material.
[0020] The textile web-shaped material can be passed through the
device for flow-through treatment of the textile web-shaped
material and then through the device for applying a binding agent,
wherein the device for flow-through treatment of the textile
web-shaped material is used as a thermobonding device for
preconsolidation.
[0021] The textile web-shaped material can be passed through the
device for applying a binding agent and then through the device for
flow-through treatment of the textile web-shaped material, wherein
the device for flow-through treatment of the textile web-shaped
material is used as a dryer.
[0022] The textile web-shaped material treated by the device for
flow-through treatment of the textile web-shaped material can be
guided, with the aid of a deflection device, to a device for
curing, wherein the textile web-shaped material is passed,
preferably without cooling, to the device for curing.
[0023] The textile web-shaped material treated by the device for
flow-through treatment of the textile web-shaped material can be
guided, with the aid of a deflection device, directly out of the
device.
[0024] The device for parallelizing fibers can be a carding unit or
a carding machine. The device for flow-through treatment of the
textile web-shaped material can be a thermobonding device or a
dryer.
[0025] The device for applying a binding agent can be a
foulard.
[0026] The transport device can comprise one or a plurality of
transport belts.
[0027] The device for flow-through treatment of the textile
web-shaped material by a gaseous treatment medium, preferably air,
comprises at least one drum having a gas-permeable drum casing,
wherein the drum casing is at least partially covered by the
textile web-shaped material to be transported in the
circumferential direction of the drum, and wherein a vacuum can be
applied in the interior of the drum. Further, there is provided a
treatment chamber at least partially surrounding the drum wherein,
upon application of the vacuum in the interior of the drum, at
least a part of the gaseous treatment medium will flow from the
treatment chamber through the textile web-shaped material arranged
on the drum casing and through the gas-permeable drum casing into
the interior of the drum.
[0028] Hereunder, exemplary embodiments of the invention will be
explained in greater detail with reference to the drawings.
[0029] In the drawings, the following is schematically shown:
[0030] FIG. 1 shows an installation for producing a textile
web-shaped material,
[0031] FIG. 2 schematically shows the passage of the textile
web-shaped material through the installation according to FIG.
1,
[0032] FIG. 3 schematically shows an alternative passage of the
textile web-shaped material through the installation according to
FIG. 1,
[0033] FIG. 4 shows an alternative installation for producing a
textile web-shaped material,
[0034] FIG. 5 shows a further alternative installation for
producing a textile web-shaped material,
[0035] FIG. 6 shows a device for flow-through treatment of the
textile web-shaped material.
[0036] FIG. 1 shows an installation 1 for producing a textile
web-shaped material. In said installation, fibers will be fed from
a fiber supply device 2 into a device 4 for parallelization of
fibers. The device 4 for parallelization of fibers preferably is a
carding unit or a carding machine. In this device 4, the fibers
will be parallelized. There is produced a pile which can be a
textile web-shaped material 7.
[0037] The textile web-shaped material 7 will be conveyed, via
transport devices 6 and 8 which in the illustrated exemplary
embodiment are transport belts, to a device 10 for applying a
binding agent. Preferably, the device 10 for applying a binding
agent is a foulard. Said transport device 8 is preferably
deflectable by means of a transport deflection device 9. Thus, the
transport device 8, i.e. the transport belt, can be adjusted. In
this manner, the textile web-shaped material 7 can be introduced
into the device 10 for applying a binding agent or, alternately, be
guided around the device 10 for applying a binding agent. In the
process of guiding the textile web-shaped material 7 around the
device 10 for applying a binding agent, the textile web-shaped
material 7 will be guided via the transport device 8 to the
transport device 12. In the illustrated embodiment, this is
represented in interrupted lines.
[0038] In the illustrated embodiment, the textile web-shaped
material 7 is passed, via transport device 8, to the device 10 for
applying a binding agent because the transport device 8 has been
adjusted with the aid of the transport deflection device in such a
manner that the textile web-shaped material 7 will be guided
directly to the device 10 for applying a binding agent.
[0039] After application of the binding agent within the device 10
for applying a binding agent, the textile web-shaped material 7
will be passed into a contact or cylinder dryer 15. The contact or
cylinder dryer 15 comprises a plurality of heated cylinders around
which the textile web-shaped material will be guided for
drying.
[0040] If the transport deflection device 9 has been adjusted in
such a manner that the device 10 for applying a binding agent will
be passed by, also the textile web-shaped material 7 will be
deflected around the contact or cylinder dryer 15. In this
alternative exemplary embodiment, the textile web-shaped material 7
will be guided via transport device 12 around the device 10 for
applying a binding agent and the contact or cylinder dryer 15.
[0041] After the textile web-shaped material 7 has passed through
the contact or cylinder dryer 15, the textile web-shaped material 7
will be guided via a transport device 16 to a device 19 for
flow-through treatment of the textile web-shaped material 7 by a
gaseous medium. Also in the case where the textile web-shaped
material 7 has been deflected around the device 10 for applying a
binding agent and the contact or cylinder dryer 15, the textile
web-shaped material 7 will be guided via transport device 16 to
said device 19 for flow-through treatment of the textile web-shaped
material 7 by a gaseous medium.
[0042] The device 19 for flow-through treatment comprises a casing
24. Internally of casing 24, a drum 18 is arranged. Drum 18 is
gas-permeable. The gas-permeability of drum 18 is effected by
perforations in the drum casing. Drum 18 can be rotatable around
the drum axis 29. Drum axis 29 is supported in casing 24. Drum 18
is surrounded by a treatment chamber 26. Within the treatment
chamber, a gaseous medium, preferably air, is arranged. The textile
web-shaped material 7 will be entered, via a deflection roll 20,
into treatment chamber 26 and will be guided over at least a part
of the drum casing. By rotating the drum 18, the textile web-shaped
material 7 will be transported in transport direction 70. When
leaving the treatment chamber 26, the textile web-shaped material 7
will be deflected around a further deflection roller 22 and be
conveyed further in transport direction 70 by means of a transport
device 32.
[0043] Within treatment chamber 26, a gaseous medium, preferably
air, is arranged. In the drum interior 28 of drum 18, there is
preferably applied a vacuum so that the gaseous medium will be
guided from treatment chamber 26 through the textile web-shaped
material 7 and into the perforated drum casing of drum 18 into the
interior. In this manner, the gaseous medium will flow through the
textile web-shaped material 7. Preferably, the gaseous medium is
heated so that the textile web-shaped material 7 can be dried
and/or that even melt fibers arranged in the textile web-shaped
material can be caused to melt.
[0044] In the illustrated exemplary embodiment wherein the textile
web-shaped material 7 has been guided via the device 10 for
applying a binding agent, the device 19 for flow-through treatment
of the textile web-shaped material is used as a dryer. Due to the
arrangement of the drum 18 and the deflecting roll 20 and
respectively 22, the illustrated device 19 for flow-through
treatment which is used as a dryer can also be referred to as an
omega dryer.
[0045] After the textile web-shaped material 7 has been guided out
of the device 19 for flow-through treatment of the textile
web-shaped material, the textile web-shaped material 7 will be
rolled onto a drum within a rolling-up device 30. Using the
installation according to FIG. 1, a nonwoven can be produced.
[0046] In the case where both the device 10 for applying a binding
agent and the contact or cylinder dryer 15 are to be passed by, the
device 19 for flow-through treatment of the textile web-shaped
material is used as a thermobonding device. In this case, there is
used a textile web-shaped material 7 comprising melt fibers.
Further, the temperature of the gaseous medium flowing through the
textile web-shaped material 7 in the device 19 for flow-through
treatment of the textile web-shaped material is selected in such a
manner that the melt fibers arranged in the textile web-shaped
material will melt and will thus consolidate the textile web-shaped
material into a nonwoven.
[0047] In FIG. 2, there is once more schematically illustrated the
passage of the textile web-shaped material 7 which is guided
through the device 10 for applying a binding agent and the device
19 for flow-through treatment of the textile web-shaped material.
The transport deflection device 9 is adjusted to the effect that
the textile web-shaped material 7 will be guided both through the
device 10 for applying a binding agent and the device 19 for
flow-through treatment of the textile web-shaped material.
[0048] Illustrated in FIG. 3 is an alternative where the transport
deflection device 9 has been adjusted in such a manner that the
device 10 for applying the binding agent will be passed by and the
textile web-shaped material 7 will be directly guided to the device
19 for flow-through treatment. Both in FIG. 2 and in FIG. 3, not
all of the cylinders 14 of the contact or cylinder dryer 15 are
shown. Further, not all of the elements of the device 19 for
flow-through treatment are shown.
[0049] The contact or cylinder dryer 15 does not need to be
provided. For example, the textile web-shaped material 7 can be
guided directly from the device 10 for applying a binding agent
into the device 19 for flow-through treatment.
[0050] In FIG. 4, an installation for producing a textile
web-shaped material 7 is shown wherein the device 19 for
flow-through treatment is arranged in transport direction 70 before
the device 10 for applying a binding agent. The installation 1
according to FIG. 4 comprises, as is the case also in the
installation 1 according to FIG. 1, a fiber supply device 2, a
device 4 for parallelizing fibers, a device 19 for flow-through
treatment, a device 10 for applying a binding agent, a contact or
cylinder dryer 15 and a rolling-up device 30.
[0051] Additionally, the installation 1 comprises, in transport
direction 70 behind the contact or cylinder dryer 15, a
flow-through dryer 40 having two drums.
[0052] The fibers supplied by the fiber supply device 2 will be
parallelized by means of the device 4 for parallelizing fibers
which preferably is a carding unit or a carding machine. The thus
produced pile can be guided by a transport device 6 and a further
transport device 43 to the device 19 for flow-through treatment.
Alternatively, the textile web-shaped material 7 can be guided by
said transport device 6 and said transport device 43 and also via
the transport device 44 directly to the device 10 for applying a
binding agent. There are provided transport deflection devices 42,
46 and 47 by means of which the transport devices 43 and 44 can be
adjusted in such a manner that the textile web-shaped material can
be deflected around the device 19 for flow-through treatment.
[0053] In the illustrated embodiment, the textile web-shaped
material 7 will be deflected around the device 19 for flow-through
treatment and be guided directly to the device 10 for applying a
binding agent. However, the transport deflection device 42, 46 and
47 can also be adjusted in such a manner that the textile
web-shaped material 7 will be guided from the device 4 for
parallelizing fibers to the device 19 for flow-through treatment
and, there, will be treated by means of a gaseous medium. After
exiting from the device 19 for flow-through treatment, the textile
web-shaped material 7 can then be guided further to the device 10
for applying a binding agent.
[0054] Behind the device 10 for applying a binding agent in
transport direction 70, the textile web-shaped material will be
guided through the contact or cylinder dryer 15 and the
flow-through dryer 40 and then, in the rolling-up device 30, be
wound onto a drum.
[0055] It is also possible to provide further transport deflection
devices, not shown in FIG. 4, so that the textile web-shaped
material 7 will be deflected alternatively around the device 10 for
applying a binding agent and/or the contact or cylinder dryer 15
and/or the flow-through dryer 40. In this manner, it would also be
possible, in an installation according to FIG. 1, to guide the
textile web-shaped material merely through the device 19 for
flow-through treatment and not through the device 10 for applying a
binding agent. If, according to FIG. 4, the textile web-shaped
material 7 is guided through the device 19 for flow-through
treatment prior to being supplied to the device 10 for applying a
binding agent, the textile web-shaped material can be consolidated
by means of a thermobonding method.
[0056] FIG. 5 shows an alternative installation for producing a
textile web-shaped material 7. The installation according to FIG. 5
is very similar to the installation according to FIG. 1. This
installation also comprises a device 19 for flow-through treatment
of the textile web-shaped material which in transport direction 70
is arranged behind the device 10 for applying a binding agent. The
textile web-shaped material will be guided from the supply device 2
through the device 4 for parallelizing fibers via transport devices
6 and 8 either to the device 10 for applying a binding agent or
alternatively around the device 10 for applying a binding agent.
For this purpose, the transport deflection device 9 is used.
[0057] When the textile web-shaped material 7 has been guided
through the device 10 for applying a binding agent, the textile
web-shaped material 7 can be guided through the contact or cylinder
dryer 15, to then be guided by means of the transport device 17 to
the device 19 for flow-through treatment.
[0058] In the case where the textile web-shaped material 7 is
deflected around the device 10 for applying a binding agent, the
textile web-shaped material 7 can be guided, via the transport
devices 12 and 16, directly to the device 19 for flow-through
treatment.
[0059] The device 19 for flow-through treatment is similar to the
device 19 for flow-through treatment according to FIG. 1 and FIG.
4. The device 19 for flow-through treatment again comprises a
casing 24, a treatment chamber 26, a drum 18, an interior 28 of
drum 18 and two deflection rollers 20, 22. Additionally, however,
the device 19 for flow-through treatment according to FIG. 5
comprises a deflection device 66. This can be seen in FIG. 6 in
which the device 19 for flow-through treatment of FIG. 5 is shown
in greater detail. Said deflection device 66 can be adjusted in
such a manner that the textile web-shaped material 7 that has
passed through the device 19 for flow-through treatment will be
guided further on the deflection roller 22 or, alternatively, to a
deflection roller 67, and from there to a device 62 for curing.
When the textile web-shaped material 7 has been guided through the
device 10 for applying a binding agent, said deflection device 66
will be adjusted in such a manner that the textile web-shaped
material 7 will be conveyed to the device 62 for curing. Between
the device 19 for flow-through treatment and the device 62 for
curing, there is preferably arranged a heating channel 60. The
textile web-shaped material 7, when being guided to the device 62
for curing, is preferably guided to the device 62 for curing
without being cooled. In the process, the textile web-shaped
material 7 will be guided within the casing 24 of the device 19 for
flow-through treatment and then through the heating channel 60 to
the device 62 for curing.
[0060] In the case where the textile web-shaped material 7 has been
deflected around the device 10 for applying a binding agent, said
deflection device 66 will be adjusted in such a manner that the
