Abstract:
A highly abrasion-resistant technical adhesive tape rolled into an adhesive tape roll includes a strip-shaped double-layer substrate with a pressure-sensitive adhesive coating on one side. The substrate includes a first fabric layer, and a second fabric layer firmly connected to each other over the entire surface by an adhesive connection layer. An adhesive tape of this type acts in a noise-damping manner and is easily processable both manually and by machine because the fabric of the first textile layer and the fabric of the second textile layer each have a basis weight of 50 g/m2 to 300 g/m2. The adhesive connection layer has a basis weight of 50 g/m2 to 300 g/m2. The adhesive tape has a thickness (D) of at least 0.5 mm. At least one tape edge has a pattern deviating from a straight line formed by a separating process.
