Abstract: A process for production of a crosswound long roll of an at least single-side-adhesive adhesive tape in which at least one adhesive side of the adhesive tape has been covered with a liner, in the form of an Archimedean spiral. The process releasably fixes a core on an axle, wherein the adhesive tape covered with the liner is wound on to the core, contacts a 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 pressure roll and curved surface of the core or adhesive tape covered with the liner, where core and pressure roll rotate in opposite directions. Further, the process unwinding the liner from a liner roll, places the liner on to the at least one open adhesive side of the adhesive tape which is guided on the pressure roll in the direction of the nip, and guides a laminate made of adhesive tape and liner on the pressure roll into the nip.
