Description
[0001] The present invention relates to a system and a method for
laying floor coverings, in particular wall-to-wall carpet, on
floors, in particular stairs.
[0002] In general today floor coverings, e.g. wall-to-wall carpets,
PVC floor coverings, or the like, are as a rule fixed in highly
stressed areas using liquid contact adhesives that contain
solvents. For instance, this is true of the area of stairs, whereby
when a floor covering is being laid contact adhesive is applied
both to the stairs as the base and to the backing of the floor
covering itself, and whereby a secure bond is achieved when these
two adhesive-coated parts are brought together.
[0003] This known procedure is complex, and the liquid contact
adhesives generally contain solvents that should be avoided because
they can be hazardous to health and because under certain
circumstances they can even pose a risk of explosion. However, one
advantage of this existing technique is that immediately after
application, a floor covering adheres securely without any waiting
period and without further setting of the contact adhesive and in
particular can even be used immediately in the step area of stairs.
It is thus possible to avoid blocking off staircases for extended
periods, which would otherwise have to be done for instance during
renovation work. In addition, during installation an installer can
immediately step on the stairs to which a floor covering has just
been glued.
[0004] For some time there has also been the option of gluing floor
coverings, in particular carpets, to floors, and therefore also to
stairs, using double-sided carpet-laying tape or double-sided
pressure-sensitive adhesive tape. For instance, known from European
patent no. 11 17 746 is a pressure-sensitive adhesive film for
laying a floor covering on a floor, which film has on both sides a
carrier layer made of plastic film, an adhesive coating with a
different adhesive strength on the top side and on the bottom side,
whereby this pressure-sensitive adhesive film is embodied with a
minimum width of 350 mm for covering large surfaces of the floor to
be covered with the floor covering. Gluing a floor covering with
such a pressure-sensitive adhesive film has the advantage that
adhesive force builds immediately and such a pressure-sensitive
adhesive film can be removed from the base leaving no residual
matter. However, over the long term under certain unusual traffic
conditions it can be possible that the adhesive force of such a
pressure-sensitive film relative to the floor covering is not as
high as can be the case with the liquid contact adhesive described
in the foregoing because the adhesive coating of such a
pressure-sensitive adhesive film, in contrast to the contact
adhesives described in the foregoing, cannot flow into the carpet
backing in order create a permanent and particularly secure bond to
all commercially available backings of floor coverings. Thus, at
particularly highly stressed locations that can be subject to
elevated shear and tensile strain, over the course of time, in
particular in the area of the riser (vertical part of a stair) and
on the step edge of stairs, a floor covering affixed in this manner
can detach or bulge at these locations. Since these
pressure-sensitive films adhere particularly well to smooth
backings of floor coverings, this problem can be even worse on
woven or textile carpet backings, which are the great majority.
[0005] It is therefore one object of the invention to overcome the
disadvantages of the prior art and in particular to provide a
system and a method for laying floor coverings, in particular
wall-to-wall carpeting, to floors, in particular to stairs, which
system provides lasting and secure anchoring of a floor covering to
a floor in particularly highly stressed areas, for instance stairs,
with relatively simple and environmentally friendly handling.
[0006] This object is inventively achieved using a system for
laying floor coverings in accordance with claim 1 and using a
method for laying floor coverings in accordance with claim 25.
[0007] Advantageous embodiments of the invention are defined in
each of the subordinate claims.
[0008] The inventive system for laying floor coverings, in
particular wall-to-wall carpeting, on floors, in particular on
stairs, has a pressure-sensitive adhesive tape and an additional
adhesive mass. In accordance with the invention, the
pressure-sensitive adhesive tape of the system has a carrier layer
that is coated with an adhesive coating on a top surface that faces
the floor covering and on a bottom surface that faces the floor or
the stair. The adhesive mass of the inventive system can be applied
at least partially for gluing a backing of the floor covering, in
particular in areas with particular shear and/or peel stresses.
That is, the adhesive mass can be applied either to the
pressure-sensitive adhesive tape, to the backing of the floor
covering, or directly to the floor.
[0009] The inventive system makes possible secure and lasting
anchoring of the floor covering to be laid to the floor, because in
accordance with the invention the floor covering is held securely
by the pressure-sensitive adhesive tape itself--and also in
shape--and because at least partially even stronger fixation of the
floor covering results due to the additionally applied adhesive
mass. Thus, in the area of the stairs the pressure-sensitive
adhesive tape prevents the floor covering to be fixed from
displacing towards the stair nose, whereby the additionally applied
adhesive mass can bond particularly securely to the backing of the
floor covering and when required hardens in a particularly secure
adhesive manner. Preferably the adhesive mass is applied as a
"mass" above and below the stair nose, since that is where the
aforesaid shear and/or peel stresses are particularly strong.
[0010] Preferred is one embodiment of the inventive system in which
the adhesive mass can be applied to the top surface of the
pressure-sensitive adhesive tape or to the floor covering backing
between the pressure-sensitive adhesive tape and the backing of the
floor covering. Thus when required it is possible that the
pressure-sensitive adhesive tape, which adheres particularly well
to the floor but can also be detached therefrom, prevents the
additional adhesive mass from coming into direct contact with the
floor, which means that, despite secure adhesion that is assured by
bonding the backing of the floor covering to the top surface of the
pressure-sensitive adhesive tape, the entire system can be detached
leaving almost no residual matter, which can be particularly
important for instance when used in rental apartments, on high-use
floors, or in large exhibition halls. The ease of handling for the
entire system is thus inventively further improved.
[0011] Preferred is one embodiment of the inventive system in which
the adhesive mass is present in a paste, liquid, or hot-melt form.
This provides simple handling and the adhesive mass of the
inventive system can still provide a good, simple, and lasting bond
to the backing of the floor covering because it can penetrate into
the backing of the floor covering so very easily.
[0012] In this context, it is particularly preferred for the
adhesive mass of the inventive system to have optimized adhesive
properties with regard to the backing of the floor covering, that
is, for the properties of the adhesive mass to be optimized for the
properties of the floor covering.
[0013] Preferred is one embodiment of the inventive system in which
the adhesive mass is an adhesive mass on a dispersion basis or a
reactive system. The adhesive mass is preferably from the group of
epoxy resin adhesives, in particular 1 K or 2 K systems,
polyurethane adhesives, in particular 1 K and 2 K systems, acrylate
or metacrylic adhesives, in particular 1 K systems, MS or MSP
polymers, hot-melt, in particular reactive hot-melt, preferably
with a PU or EVA base. Particularly preferred are humidity-setting
1 K reactive systems or thermosetting, thermoactivated 1 K systems.
Appropriate adhesives provide particularly lasting and secure
anchoring of the floor covering to be fixed.
[0014] In order to further improve the inventive system, in
accordance with one preferred embodiment of the invention the
adhesive mass can be present in a cartridge, a tube, or a bag, and
can be processed using a glue gun that is suitable for receiving
the cartridge, the tube, or the bag. The adhesive mass can also be
present in a bottle, a can, or a pressure tank from which the
adhesive mass can be removed. The adhesive mass can also be present
as a bar of adhesive that is not contained in a covering and that
can then preferably be processed using an appropriate hot glue
gun.
[0015] Depending on the floor covering to be glued, in accordance
with one preferred embodiment the carrier layer of the
pressure-sensitive adhesive tape of the inventive system can
comprise a fiber fabric, woven fabric, non-woven fabric, or plastic
film. The non-woven fabric can particularly preferably be a
synthetic non-woven fabric or a non-woven fabric made of viscose,
cotton; or spun rayon. The plastic film can particularly preferably
comprise polyethylene (PE), polypropylene (PP), polyolefin (PO),
polyester (PET), or polyamide (PA).
[0016] In particular, when the carrier layer of the
pressure-sensitive adhesive tape of the inventive system comprises
plastic film, the pressure-sensitive adhesive tape of the system
can have at least one additional textile structure on its top
surface for further improving the stability of said tape. This
additional textile structure can in particular increase the
dimensional stability of the pressure-sensitive adhesive tape of
the inventive system in a possibly desired detaching procedure and
thus improve the handling of the system in that detachability
leaving almost no residual matter can be further improved or
facilitated.
[0017] In order to further improve the processability of the
inventive system, in accordance with one preferred embodiment it is
possible for the pressure-sensitive adhesive tape to have a
removable protective film on at least its top surface. In this
manner the pressure-sensitive adhesive tape that has already been
laid out and glued at its lower surface can still permit the floor
covering to be placed thereupon, loose first for orientation and/or
cutting, whereby the actual gluing does not take place until after
such orientation/cutting has been performed, the protective film
has been folded back and removed by section, the additional
adhesive mass has been applied, and the floor covering to be fixed
is then pressed thereupon.
[0018] Particularly preferred is an embodiment of the inventive
system in which the removable protective film is embodied at least
on the top surface of the pressure-sensitive adhesive tape in an
anti-slip manner. In this way a person using the inventive system
can safely step on the protective film, that has not yet been
removed, of the inventive pressure-sensitive adhesive tape that has
already been laid on the floor, which further improves occupational
safety and thus also handling of the system in accordance with the
invention. This applies in particular in connection with employment
when laying floor coverings on stairs, where otherwise the risk of
injury because of slipping is particularly high. The anti-slip
design can preferably comprise nubs, depressions, grooves, or
perforation with perforation apertures. One particularly preferred
embodiment with perforation is described further below.
[0019] Furthermore preferred is an embodiment of the inventive
system in which the pressure-sensitive adhesive tape has a width in
the range from 100 mm to 2000 mm, in particular in a range from 140
mm to 1500 mm, and in particular in a range from 170 mm to 300 mm,
whereby the width when employed for stairs is in particular 230 mm
and when employed on floors is at least 350 mm. Thus preferably
large surface or even complete surface gluing and covering of the
floor to be provided with the floor covering is possible, whereby
in the case of stairs the 230 mm coincides exactly to the
conventional stair height. The processability of the inventive
system is thus particularly improved and therefore simplified,
whereby the stability of the fixing of the floor covering is
improved by complete surface or large surface application of the
pressure-sensitive adhesive tape of the inventive system in
accordance with this preferred embodiment because of the enlarged
adhesive surface. Even strip-wise and/or sectional design and
application of the pressure-sensitive adhesive tape of the
inventive system is preferably possible and can for instance be
particularly desired and advantageous in constrained physical
circumstances.
[0020] The improvement to the inventive adhesiveness can even be
increased in that the additional adhesive mass is applied over a
large surface or even over the complete surface for gluing the
floor covering.
[0021] In accordance with the invention, the carrier layer of the
pressure-sensitive adhesive tape of the system in accordance with
one preferred embodiment preferably has a thickness in a range from
10 to 200 .mu.m, preferably in a range from 25 to 150 .mu.m, and
especially preferably in a range from 50 to 120 .mu.m.
[0022] In order to be able to adjust the adhesive forces
advantageously, and in order to provide good adhesive force while
simultaneously further improving the handling of the inventive
system with a removal option that leaves almost no residual matter,
the bottom surface of the pressure-sensitive adhesive tape can have
an adhesive coating with lower adhesive strength than the adhesive
strength of the adhesive coating on the top surface. In particular
in the case of large surface gluing and application of the
pressure-sensitive adhesive tape in accordance with the inventive
system, this still attains reliable adhesion over time.
[0023] Different adhesive application weights are provided on the
two surfaces of the pressure-sensitive adhesive tape for attaining
the different adhesive strengths, whereby the surface with the
greater adhesive strength has a higher adhesive application
weight.
[0024] Thus the adhesive application weight can preferably be in
the range from 5 to 250 g/m.sup.2, at least on the top surface and
particularly preferably in the range from 8 to 200 g/m.sup.2, at
least on the lower surface, especially particularly preferably from
10 to 150 g/m.sup.2.
[0025] In addition, preferably at least the adhesive coating on the
top surface of the pressure-sensitive adhesive tape of the
inventive system can comprise softener-resistant adhesive. The
adhesive coating of the top and bottom surfaces of the
pressure-sensitive adhesive tape of the inventive system
particularly preferably comprises softener-resistant adhesive.
[0026] Also preferred is one embodiment in which the adhesive
coating of the pressure-sensitive adhesive tape of the inventive
system comprises hot-melt adhesive or, particularly preferred,
acrylate adhesive. Thus especially when interacting with the
inventive adhesive mass, particularly secure anchoring of the floor
covering to be laid can be especially assured over an extended
period in accordance with the invention.
[0027] Furthermore preferred is one embodiment of the inventive
system in which the adhesive coating of the pressure-sensitive
adhesive tape comprises different adhesives on the top and on the
bottom surfaces. Thus appropriate adjustment results in a
particularly secure and lasting anchoring of the floor covering to
be fixed. In particular it can be taken into account that an
additional synergy effect occurs between the adhesive coating of
the pressure-sensitive adhesive tape on the top side and the
additional adhesive mass such that the resultant adhesion to the
backing of the floor covering to be fixed is particularly strong
and lasting.
[0028] Preferably the adhesive strength of the pressure-sensitive
adhesive tape without additional adhesive mass of the system has an
adhesive force (measured as peel force in accordance with DIN 1939)
at least on the bottom surface on the order of magnitude of 1 to 50
N/25 mm, in particular from 3 to 40 N/25 mm, and in particular from
5 to 30 N/25 mm.
[0029] In order to minimize or avoid deterioration in the adhesive
force and the fixing effect of the inventive system, which can
occur due to the effects of moisture if for instance a floor
covering is to laid on a flooring plaster (Keene's cement) floor
that has some residual moisture, for instance, the carrier layer
and the adhesive coating of the pressure-sensitive adhesive tape of
the inventive system is preferably water vapor permeable with an sd
value in the range from 0.2 .mu.m to 30 .mu.m, preferably in a
range from 0.5 .mu.m to 10 .mu.m.
[0030] This water vapor permeability can also preferably be
attained in that the carrier surface and/or the adhesive coating of
at least one of the surfaces of the pressure-sensitive adhesive
tape of the inventive system is perforated with perforation
apertures that are distributed across the entire surface and spaced
from one another preferably at a distance of less than 10 cm and
that have a cross-sectional surface of less than 4 mm.sup.2. The
corresponding perforation apertures in the carrier layer and
adhesive coating of at least one of the surfaces are preferably
arranged in alignment.
[0031] The preferred anti-slip design of the removable protective
film of at least the top surface of the pressure-sensitive adhesive
tape of the inventive system as described in the foregoing can
particularly preferably be embodied by the perforation described in
the foregoing, whereby the aligned arrangement of the perforation
apertures in the carrier layer and the adhesive coating affects at
least one of the surfaces preferably also the arrangement of the
perforation apertures of the perforation of the removable
protective film.
[0032] In order to further improve processability, in accordance
with one preferred embodiment the pressure-sensitive adhesive tape
of the inventive system is rolled into a roll and processable by
unrolling.
[0033] In the inventive method for laying floor coverings, in
particular wall-to-wall carpet, on floors, in particular stairs, a
system is provided, in particular a system in accordance with the
type described in the foregoing, whereby the system has a
pressure-sensitive adhesive tape and an adhesive mass, and whereby
the pressure-sensitive adhesive tape has a carrier layer that is
coated with an adhesive coating on a top surface that faces the
floor covering and on a bottom surface that faces the floor or the
stair. In the inventive method, the pressure-sensitive adhesive
tape is applied to the floor, preferably over a large surface or
the complete surface, or even by section. The adhesive mass is at
least partially applied, in particular in areas with particularly
high shear and/or tensile strain, and the backing of the floor
covering is glued to the corresponding system. Using the inventive
method, the adhesiveness of the pressure-sensitive adhesive tape is
combined with the lasting and secure anchoring from the additional
adhesive mass, which results in simple handling. In addition, the
floor covering is already held in shape and position by the
pressure-sensitive adhesive tape during the setting time for the
adhesive mass. The adhesive mass, which then has set and later has
dried, supports the secure gluing of the floor covering over the
further period of use. Thus, at first the pressure-sensitive
adhesive tape can be a type of installation aid, ensuring that it
is possible to walk on the floor covering immediately after it is
laid without disturbing its shape or position. Then the additional
adhesive mass can also ensure improved long-term stability, even
under high stress. In addition to the described combined effect
(immediate fixation and long-lasting adhesive force), the inventive
use of both a pressure-sensitive adhesive tape and an adhesive mass
offers detachability from the floor, and this detachability also
leaves almost no residual matter. When using an adhesive mass
alone, as is the practice in the prior art, none can be detached
from the floor leaving almost no residual matter.
[0034] In order to further improve the handling of the inventive
method, in particular in order to provide detachability with almost
no residual matter, in accordance with one preferred embodiment of
the method the adhesive mass is applied to the top surface of the
pressure-sensitive adhesive tape on the adhesive coating there or
to the floor covering backing and the backing of the floor covering
is glued to the corresponding system.
[0035] In accordance with another preferred embodiment of the
inventive method, the floor can preferably be covered with the
pressure-sensitive adhesive tape over a large surface or over the
complete surface.
[0036] The adhesive mass can also be applied to an entire surface,
preferably the entire surface of the pressure-sensitive adhesive
tape. This results in inventively preferred anchoring over a large
surface.
[0037] In order to facilitate displacement and/or cutting back of
the floor covering to be fixed, in accordance with one preferred
embodiment of the inventive method the pressure-sensitive adhesive
tape can be provided, at least on its top surface, with a removable
protective film that is removed prior to applying the adhesive mass
and/or prior to gluing the floor covering.
