Description
[0001] The invention relates to a device for unwinding or applying
adhesive tape, especially double-sided adhesive tape, which is to
be unwound from a roll of adhesive tape.
[0002] A plurality of unwinding aids is known from the state of the
art for unwinding adhesive tapes. For this purpose, a roll of
adhesive tape is usually taken up completely in a housing, in which
it is guided over one or several studs to an opening of the
housing, from which the adhesive tape can be pulled and unwound for
processing. These unwinding aids generally are structurally
expensive and therefore frequently too expensive for the
user/consumer for a possibly only single use, so that many do
without using an unwinding aid and apply the adhesive tape
"freehandedly" directly from an adhesive tape roll to a substrate.
However, especially when applying very wide adhesive tapes, as
used, for example, for laying wall-to-wall carpeting, when gluing
base plates, which must, moreover, be applied accurately over a
greater distance, it is almost impossible to bring this about
without an unwinding aid.
[0003] It is therefore an object of the invention to provide a
device, which can be produced particularly easily and therefore
inexpensively, for applying or unwinding adhesive tape, especially
double-sided adhesive tape, rapidly and precisely on a
substrate.
[0004] This objective is accomplished pursuant to the invention
with a device for unwinding or applying adhesive tape, which is to
be unwound from a roll of adhesive tape, with the distinguishing
features of claim 1. Advantageous developments of the inventive
object are given in the dependent claims 2 to 6.
[0005] Pursuant to the invention, the device for unwinding or
applying adhesive tape, which is to be unwound from a roll of
adhesive tape, consists of a discoid unwinding body and of a
roll-accommodating device, mounted thereon. The device thus
consists only of two parts, which can be constructed integrally
connected with one another or also separately from one another.
This two-part construction of the device can be produced very
simply and easily and therefore also inexpensively. The discoid
unwinding body and the roll-accommodating device have a common
central axis, about which the roll of adhesive tape roll rotates
during the unwinding process. Moreover, the inventive, discoid
unwinding body has a supporting surface, on which the roll of
adhesive tape is seated fully laterally. Moreover, the supporting
surface not only supports the roll of adhesive tape lying on it,
but also offers protection against contamination by dust or other
contaminants, which easily adhere to the sides of the rolls of
adhesive tape. The roll-accommodating device protrudes from the
supporting surface of the unwinding body. The external diameter of
the roll-accommodating device is slightly less than the internal
diameter of the roll of adhesive tape, which is to be accommodate
thereon, and preferably by 1 or 2 mm, so that the roll of adhesive
tape can be slipped easily onto the external diameter of the
roll-accommodating device. In this way, a roll of adhesive tape can
be placed easily on the roll-accommodating device and held by it
thereon and unwound.
[0006] Pursuant to an advantageous further development of the
inventive device, the supporting surface of the discoid unwinding
body is constructed as a sliding surface. It is particularly
advantageous if the whole of the supporting surface is constructed
as a sliding surface. This permits the adhesive tape, resting fully
on the supporting surface, to be unwound easily from the device
with little friction.
[0007] According to a further preferred embodiment, a silicone
paper, which is provided on the support surface, is particularly
suitable as lubricant and release agent. The silicone paper serves
as a release layer between the sides of the rolls of adhesive tape
and the unwinding body, so that these cannot adhere to one another
and the adhesive tape can be unwound easily from the device.
[0008] In a further, preferred embodiment, the roll-accommodating
device has a peripheral surface, which accommodates the roll of
adhesive tape and protrudes from the supporting surface preferably
at a height of 2 cm.
[0009] Preferably, the discoid unwinding body is circular and has a
diameter ranging from 10 to 30 cm, depending on the size of the
roll of adhesive tape. A diameter of 19.5 cm is particularly
advantageous. An also circular recess is provided in the center of
the discoid unwinding body and has a diameter ranging from 30 to 90
mm. The diameter of the recess corresponds to the diameter of the
roll-accommodating device, which is disposed in the recess. The
roll-accommodating device can be provide as a ring in the recess or
also disposed therein as a thick disk, so that the whole of the
recess is filled thereby. The thickness of the discoid unwinding
body preferably ranges from 0.5 to 15 mm. In particular, the
discoid unwinding body is about 5 mm thick. Instead of a discoid
unwinding body, the roll-accommodating device may have two or
preferably three elevations, which are at a uniform distance from
the center of rotation and, in the interior of the recess, form a
holding device for the roll of adhesive tape in the form of a
two-point or three-point mounting. If the device, in a preferred
manner, consists of cardboard, the elevations can be produced, for
example, by bending up the cardboard when die-cutting it. They may,
however, also be glued on, constructed as plastic or metal knots
and fastened to the cardboard by known procedures.
[0010] Since the thickness of the unwinding body determines the
distance of the adhesive tape strip from a wall, on which the
adhesive tape is to be applied and which is perpendicular to a
substrate, the device, during the application of the adhesive tape,
being placed with its surface, opposite and parallel to the
supporting surface, on the substrate, a small thickness of the
unwinding body is advantageous, if the adhesive tape is to be
applied close to the substrate at the wall perpendicular to it. A
greater distance from the substrate at the wall may also be
desirable, if, for example, wider base plates are to be mounted on
a wall. An unwinding body with a greater thickness is to be used
for this purpose.
[0011] It is, furthermore, of advantage if the discoid basic body
is produced from a hard and solid material, such as a metal or
plastic. Solid cardboard is a particularly advantageous material,
since it is very advantageously priced and thus lowers the
manufacturing cost enormously. In the case of an advantageously
priced manufacturing process of the device from cardboard, it is
therefore possible to add the inventive device for unwinding and
applying the adhesive tape at the same time to each adhesive tape
roll, so that a compact unit is obtained. This is of advantage
particularly for the consumer in that, whenever he purchases an
adhesive tape roll, he also at the same time, has the corresponding
unwinding device in hand.
[0012] The inventive device for unwinding and applying adhesive
tape, unwound from a roll of adhesive tape by means of a preferred
embodiment, is explained in greater detail in the following
description and shown in the drawings in which
[0013] FIG. 1 shows a cross section through the inventive device
for unwinding and applying adhesive tape, which is unwound from a
roll of adhesive tape and

[0015] FIG. 1 shows a cross section through the inventive device
for unwinding and applying an adhesive tape, which is unwound from
a roll of adhesive tape. In the center of the discoid unwinding
body 1, there is a recess 6, in which a device 2 for accommodating
the roll is disposed. The device 2 for accommodating the roll
protrudes perpendicularly to the discoid unwinding body 1 from this
unwinding body 1 or from a supporting surface 3 of the discoid
unwinding body 1. A roll 5 of adhesive tape is indicated by the
broken line and the reference symbol 5. It is placed on the device
2, for accommodating the roll, guided slightly about a peripheral
surface 4 of the unwinding device 2 and rests with its underside on
the supporting surface 3 of the discoid unwinding body 1. A lower
section of the peripheral surface 4 of the unwinding device 2 is
connected with the discoid unwinding body 1. For applying adhesive
tape on a wall, the unwinding body is placed with its underside 8
on a substrate or floor and, at the same time, placed with a
peripheral surface 7 of the discoid unwinding body 1 against the
wall, which is perpendicular to the substrate.
[0016] FIG. 2 shows a plan view of the inventive device of FIG. 1
for unwinding and applying adhesive tape, which is to be unwound
from a roll of adhesive tape. The roll-accommodating device 2 is
disposed in the recess 6 in the center of the discoid unwinding
body 1. An adhesive tape 5, lying laterally on the discoid
unwinding body, is indicated by the broken line.
