ADHESIVE TAPE AND METHOD TO MANUFACTURE ADHESIVE TAPE Russian patent published in 2015 - IPC C09J7/02 B31F5/06 B32B7/12 B65H19/18 

FIELD: technological processes.

SUBSTANCE: group of inventions relates to an adhesive tape, method of its manufacturing and method of automatic roll replacement. An adhesive tape (10) for use in devices with automatic roll replacement, including a double-sided adhesive tape (100) and a separated tape (200) from several self-adhesive layers. To produce an adhesive tape, which provides for easy and reliable application without sticking to the rear side of the upper layer of the roll material, at least the third self-adhesive layer (230) of the separated tape (200) has smaller width compared to a fixing layer (220) of the separated tape (200). Thus practically non-sticky area (240) is produced on the lower surface (212) of the separated layer (210). The method to manufacture an adhesive tape consists in fixation of different layers and making a gash of the third self-adhesive layer (230) of the separated tape (200). The method of automatic roll replacement consists in connection of wound roll material with other roll material and attachment of the adhesive tape to the end of the upper web of the wound roll material.

EFFECT: invention provides for easy and reliable application of adhesive tape in devices with automatic roll replacement.
