DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a method for affixing a double sided adhesive tape onto an electrical conduit or other conduit for the purpose of attaching the conduit to a surface as defined in the preamble of claim 1. The invention also relates to a means for the execution of the method as defined in more detail in the preamble of the first device claim. In addition the invention relates to a tape holder or dispenser for a double sided adhesive tape intended to be used together with said device. Finally the invention relates to a use of the method and the device for the attachment of a conduit to a surface.
It is known to attach an adhesive layer and a protective paper onto conduits already during the manufacture of the conduits. When used the protective paper is removed and the conduit is pasted on. However, this results in unnecessary additional costs and adhesion problems at those times when an adhesive attachment is not wanted, for instance when the conduit is drawn through a pipe.
DE 827 372 discloses a procedure using a storage drum with a glue-covered electrical conduit together with a pressure roll exhibiting a handle. When using the device the conduit is rolled off against the surface below and is immediately attached to it by pressing with the pressure roll. Furthermore, the international patent application WO 9520834 describes a handle with a roller for pressure attachment of a conduit coated with glue or tape on a surface or pressure attachment of a conduit onto a surface covered with glue. However, none of these devices can be used for the affixing of an on two sides adhesive tape onto the conduit directly in connection with the mounting of the conduit.
DE 33 39 143 has earlier proposed a device for the affixing of an on two sides adhesive tape onto a conduit. Then the conduit is attached to a surface which first has been provided with a coating of contact glue. It comprises a back-pack device for a "flat band conduit" with a cable drum and a roll holder for an on two sides adhesive tape. They are simultaneously fed out between two rolls, one of these being driven by a motor.
This device has the drawback that it is unnecessary heavy because the entire cable roll must be carried on the back. Furthermore, it is not possible to discontinue the tape affixment for instance when passing through a wall or fitting the conduit in a pipe. Neither it is possible to switch the device between different conduits, for instance between different dimensions or between different conduits when several conduits are installed at the same time, without having several devices which results in increased costs.
Accordingly, the object of the present invention is to set aside the drawbacks of the Prior Art with a method which makes it possible to affix a double sided adhesive tape also on the middle of a conduit, which is easily switched between different conduits, which does not require any heavy lifting and which is easy to perform in various environments and narrow spaces. Furthermore, the object of the invention is to provide a device intended for the performance of the method which is easy to change-over between different conduit sizes and/or different tape widths, which has a low weight, which is simple and uncomplicated in construction as well as exhibits few moving parts and which has low manufacturing costs. A further object of the invention is to provide a device by which a conduit can directly be attached to a surface. Moreover, the object of the invention is to provide a tape holder, specially a disposable tape dispenser, intended to be used together with said device. A further object of the invention is to provide a use of the inventive method and device for the installation of specially electrical conduits.
These objects are achieved with the invention having the characteristic features set forth in the following claims.
A device for the performance of the inventive method comprises a body and a channel carrier exhibiting at least one channel intended for a conduit. Together with an opposite or facing
