ABSTRACT:
The invention relates to a device for applying adhesive mounting tape according to the preamble of claim
1
.
Devices which can be used to apply adhesive tape from a roll onto a surface are known. The adhesive tape which is thus applied is used both for attaching certain elements, in particular skirting boards when carpeting is being laid, and for sticking together, for example, cardboard boxes. These known devices have a housing with a handle and an application roller, there being arranged in the housing an adhesive tape which is wound up on a roll and can be routed outwards, via the roll, through a slit arranged in the housing in the region of the roll and can be applied to the desired location. However, these devices are only suitable for thin adhesive tape which can be routed outwards in a narrow slit beside the roll and can be wound up on a roll with a relatively small diameter, in order that the size of the devices, which are designed as hand-held implements, remains manageable.
U.S. Pat. No. 4,707,202 describes a device for applying adhesive tape to wall sections from a roll. The device has two application rollers, of which one is approximately half the width of the adhesive tape and the second has an upside-down V-shaped profile, in order to press the adhesive tape into a corner. By virtue of the V-shaped profile roller, the adhesive tape is given a right-angled form and, in this form, is adhesively bonded, in the corner region, to two surfaces adjacent to the corner.
CH 377 682 describes a hand-held implement for applying a self-adhesive tape over an edge. The hand-held implement has a pressure-exerting lever and a contact lever, which project out of a base plate of the implement and each bear a running roller. The adhesive tape is drawn off from an adhesive-tape supply roll and is pressed on by means of a roller. The implement serves for packaging purposes and, accordingly, is suitable for outer edges.
GB 2 274 448 A describes a device for dispensing and applying an adhesive tape. The device has a base plate which is guided on wheels, on which an adhesive-tape supply roll is arranged and from which the adhesive tape is unwound. The device has adjustable rollers in order to fold, and smooth, the unwound tape at a top edge, the device being provided for applying adhesive tape to a smooth surface.
DE 37 36 376 C1 likewise describes a hand-held implement for transferring, in particular, an adhesive film from a backing film onto a surface. The adhesive film is fed, from a supply reel, to an application element, which projects from the hand-held implement and is intended for pressing the adhesive side against the surface, the adhesive tape being designed such that the adhesive remains on the surface and the adhesive-bearing substrate is guided back onto a winding-up reel of the hand-held implement again. The substrate with the adhesive film runs over a projecting application strip which, although, in principle, permitting an adhesive strip to be adhesively bonded in an inner corner, is unsuitable, without interrupting the application operation, for fixing adhesive tape securely and reliably on outer corners and positioning the adhesive tape round the latter.
EP 0 380 977 A1 likewise describes a hand-held implement for transferring a film from a backing film onto a substrate. The adhesive-bearing film is unwound from a supply reel and fed, via an application element, to a winding-up reel. The application element projects out of the housing and is designed as a constituent part of a triangular region, triangularly tapering transverse walls being integrally formed on for this purpose. The triangular region is fixedly connected to the housing of the hand-held implement. Although the triangular form makes it possible for adhesive strips to be applied in an inner corner, the continuous application of adhesive strips round an outer corner is only possible to a limited extent.
Also known, for the purpose of fastening, in particular, floor/wall finishing strips when carpeting is being laid, are skirting-board systems which are attached to the corresponding walls in the conventional manner by nailing or drilling, pinning and subsequent fixing by screws. As skirting-board systems, use is preferably made of core-type skirting boards. These core-type skirting boards serve as carriers for, for example, textile floor coverings. Since there are often irregularities on those regions of the walls which are arranged in the vicinity of the floor, it is necessary for such skirting boards to be fixed firmly on the wall, in order that subsequent detachment of the skirting boards as a result of irregularities of this type can be avoided. For this reason, an adhesive tape which is adhesive on both sides and has a certain minimum thickness, in order, on the one hand, to be able to compensate at least partially for the irregularities in said wall regions and, on the other hand, to have sufficient strength to allow the core-type skirting boards to be retained on the wall sections, has been developed. This adhesive tape is used, for example, in buildings made of prefabricated concrete elements.
The conventional method which has been used up until now for applying such an adhesive tape has been a manual one. For manual application of such an adhesive tape, that side which is not coated with a protective layer is applied to the wall and pressed on by hand. The manual pressing-on operation, however, cannot ensure that the adhesive tape adheres equally well to all locations on the wall. Secondly, manual application requires a relatively large amount of physical exertion in terms of the relatively large number of metres which are necessary for laying such skirting-board systems. Once the adhesive tape has been pressed on, the protective layer or cover layer can be drawn off, with the result that the second adhesive layer is exposed and the corresponding skirting-board system can be press-fixed on the wall.
A further disadvantage with manual application of the adhesive mounting tape is that the accuracy by which the distance of the top edge of the adhesive mounting tape from the floor can be maintained is restricted and, as a result, it may be necessary, once the respective skirting board has been attached, to do follow-up work in order to remove the protruding adhesive tape.
Also known are systems in which the skirting boards are coated with cartridge adhesive or the adhesive is applied in the wall region and the skirting boards are then pressed onto the wall. Systems of this type too are relatively time-consuming and do not ensure sufficient accuracy, upon application of the adhesive tape, in terms of uniform application and, as a result, achieving a high adhesive force and in terms of maintaining the distance of the top edge of the adhesive tape from the floor region or a corresponding reference edge.
The object of the present invention is thus to provide a device which is intended for feeding double-sided adhesive mounting tape to, in particular, flat sections, which, even in the case of inner and outer corners in the wall region, does not necessitate an interruption in the continuous application process of the adhesive mounting tape, and by means of which it is possible to achieve a high application rate for the adhesive mounting tape along with improved adhesive behaviour and reduced physical exertion.
This object is achieved by a device with the features according to claim

Expedient developments are defined in the dependent claims.
According to the invention, the device for applying adhesive mounting tape, in particular double-sided adhesive mounting tape, which is preferably wound up on a roll and serves for attaching elements to sections of walls, floors or ceilings and, in particular, to floor/wall finishing strips, has a handle or grip by means of which the device can be guided in those locations of the respective wall regions which are predetermined for the application of the adhesive mounting tape. According to the invention, the device has an application element for the adhesive mounting
