Method of cutting a web having at least an adhesive side laying on a protective substrate into individual finished elements

摘要

A cross punching process defines a single stamping line to divide the material length across its full width, into individual punched parts. The line deviates from the straight, and the covering material of the length is not or only slightly cut. The cross punching is carried out at an angle of mainly 90 deg. to the direction of the material length. The line may be curved, wave-shaped, saw tooth-like and/or zig-zag-shaped. The length consists of a layer of adhesive or a base material with an adhesive coating on one or both sides. The covering material has an anti-adhesive coating on both sides, and the degree of deflection of the anti-adhesive coating is the same as that of the adhesive material.
