Embodiment Construction

[0042] Advantageous embodiments of the method are described below by using the figures described in more detail, but these embodiments and the figures themselves should not be interpreted as limiting.

[0043] figure 2 Possible starting materials are shown, which are intended for processing by the method according to the invention, or on which the first steps of the method have already been carried out. The usual method is to cut a large number of individual adhesive tape strips from one adhesive tape open width. figure 2 Only three individual adhesive tape strips 2 , 3 , 4 are shown next to each other in the machine direction, which have been cut from the adhesive tape without loss in the cutting device. The adhesive tape web and thus the adhesive tape strips 2 , 3 , 4 lie on the first liner 1 which was not damaged during the cutting operation of the adhesive tape strips 2 , 3 , 4 .

[0044] A separate strip of adhesive tape comprises a backing material 21, 31, 41 provide...

Abstract

A method produces adhesive tapes which are adhesive at least on one side, wherein an adhesive tape web, in which the at least one adhesive side is covered by a first liner, is guided into a cutting device in which a total of N individual adhesive tape strips located next to one another are produced in the machine direction from the adhesive tape web. Every other adhesive tape strip is removed from the first liner and is applied to a second liner in each case having a spacing a between the individual adhesive tape strips. The liners are cut between the adhesive tape strips located on the first liner and on the second liner, and the individual adhesive tapes, together with the liner strips, are wound up in a total of X rolls in a form of an Archimedean spiral.

Description

technical field [0001] The invention relates to a method of producing an adhesive tape with a protruding liner. Background technique [0002] At the end of the production process, the adhesive tape coated with adhesive on one or both sides is usually wound up in the form of an Archimedean spiral to obtain a roll. Before the winding process, the adhesive tape is applied to a protective cover material (also known as release material), which is rolled up with the adhesive tape, in the case of adhesive tapes which are adhesive on both sides , the purpose is to prevent the (pressure-sensitive) adhesives from touching each other or, in the case of adhesive tapes which are tacky on one side, from sticking to the backing. This type of protective covering material is known by those skilled in the art as a release liner or liner. Liners are used not only for protective covering of adhesive tapes that are adhesive on one or both sides, but also for protective covering of labels. [...
