Embodiment

[0142] To illustrate the invention, the method is carried out according to the following scheme:

[0143] coating

[0144] The coating was carried out on a laboratory coating device with a web width of 30 cm. The basic functional parts of this device are the unwinding of the uncoated carrier bale, the adhesive applicator for achieving a defined wet film thickness, four individually temperature-controlled Floating nozzle tunnel dryer in warm zone (5 m long) and winder for winding coated and dried product.

[0145] The applicator mechanism used was a coating knife with a V-shaped profile positioned radially on a coating roll rotating in the same direction as the web, through which the carrier was passed (roller knife method ( knife-over-roll process)). The distance between the fabric to be coated and the bottom edge of the coating knife is set such that after drying the desired weight of pressure-sensitive adhesive (PSA) per unit area according to the examples is obtained.

Abstract

The invention relates to a method for producing an adhesive tape intended more particularly for wrapping cables, comprising an open textile carrier and a pressure-sensitive adhesive coated on one side thereof. A shear viscosity of the pressure-sensitive adhesive, at a temperature of 25 DEG C. during coating from dispersion, is 200 to 100 000 Pa*s at a shear rate of 10-2 s-1 and is 0.1 to 10 Pa*s at a shear rate of 100 s-1.

Description

technical field [0001] The present invention relates to a method of manufacturing an adhesive tape intended more specifically for wrapping cables and comprising an open cell textile carrier and a pressure sensitive adhesive coated on one side thereof. Background technique [0002] Adhesive tapes have been used industrially for the manufacture of cable looms for a long time. In this case, the adhesive tape is used to bundle a large number of electrical leads before installation or in a state ready for installation, in order to reduce the space occupied by the lead bundle by bundling, and additionally to obtain a protective function. [0003] Testing and classification of adhesive tapes for cable sheathing in the motor vehicle industry according to standards such as LV 312-1 "Protection systems for wire harnesses in motor vehicles, adhesive tapes" as bonding standard for Daimler, Audi, BMW and Volkswagen companies; test guideline" (10 / 2009), or the extended version of Ford sp...
