Method for producing an adhesive tape

摘要

The present invention relates to a method for producing an adhesive tape (2). The adhesive tape (2) possesses a tapelike carrier (3) and at least one strip (4; 4a, 4b) of adhesive which is applied to the carrier (3) on at least one side. Here, first of all, a carrier web (1), coming from a supply unit (7), is supplied to at least one coating unit (9, 10). The coating unit (9, 10) then generates the at least one strip (4; 4a, 4b) of adhesive on the carrier web (1) in its longitudinal extent, by carrying out coating with an adhesive. Lastly, the carrier web (1) is slit in the longitudinal direction into the individual adhesive tapes (2); the two last-mentioned method steps may also be run in the opposite order.

主权项

1. A method of making adhesive tapes, the method comprising the steps of:
feeding a substrate web having two opposite faces from a supply to two coating devices; applying with the coating devices to each of the faces an adhesive coating to form on each face at least one longitudinally extending adhesive strip with the strips transversely offset from each other and each face having at least one longitudinally extending adhesive-free strip; and cutting the substrate web longitudinally between the adhesive strips into individual adhesive tapes each having a respective one of the strips.
