摘要： Method for producing a crosswound long reel of an adhesive tape which is adhesive at least on one side, in which method the at least one adhesive side is covered by a liner, in the form of an Archimedean screw, wherein a core is fixed releasably on a spindle, onto which core the adhesive tape which is covered by the liner is wound, a pressure roller is in contact with the circumferential surface of the core or with the adhesive tape which is covered by the liner and is already wound onto the core, in such a way that the result is a roller nip between the pressure roller and the circumferential surface of the core or with the adhesive tape which is covered by liner, wherein the core and pressure roller rotate in opposite directions, the liner is unwound from a liner roller, the liner is placed onto the at least one open adhesive-agent side of the adhesive tape which, lying on the pressure roller, is guided in the direction of the roller nip, and, lying on the pressure roller, the laminate comprising adhesive tape and liner is guided into the roller nip, the adhesive tape which is covered by the liner is wound on the core, wherein the liner roller of the liner and the pressure roller are moved to and fro synchronously in a movement parallel to the spindle of the long reel, wherein the liner has a greater width than the adhesive tape (in each case in relation to the transverse direction of liner and adhesive tape) and is laminated onto the adhesive tape in such a way that it protrudes at both edges of the adhesive tape.
