Claim Text:
1. A process for production of a crosswound long roll of an at least single-side-adhesive adhesive tape, wherein at least one adhesive side of the adhesive tape has been covered with a liner, wherein the crosswound long roll is in the form of an Archimedean spiral, the process comprising releasably fixing a core on an axle, wherein adhesive tape covered with the liner is wound on to the core, fastening a liner roll, a guide sleeve and a pressure roll to a movable lever, wherein cylindrical bodies of the guide sleeve and the liner and pressure rolls, when viewed from above, are parallel with respect to each other and co-planar defining a single plane, contacting the pressure roll with a curved surface of the core or with the adhesive tape which has been covered with the liner and already wound on the core, in such a way as to give a nip between the pressure roll and the curved surface of the core or the adhesive tape covered with the liner, wherein the core and the pressure roll rotate in opposite directions, unwinding the liner from the liner roll, feeding the adhesive tape into the single plane onto the guide sleeve between the liner and pressure rolls, wherein the adhesive tape is fed to the guide sleeve at an angle with respect to the single plane defined by the parallel and co-planar liner roll, guide sleeve and pressure roll, placing the liner onto the at least one open adhesive side of the adhesive tape which is guided on the pressure roll in the direction of the nip, guiding a laminate made of the adhesive tape and the liner on the pressure roll into the nip, and moving the lever, with the guide sleeve and the liner and pressure rolls, in an axial direction with respect to the core while winding up the adhesive tape covered with the liner onto the core, wherein the liner is wider than the adhesive tape, based in each case on the transverse direction of the liner and the adhesive tape, and is laminated on to the adhesive tape such that the liner protrudes at both edges of the adhesive tape.
