  • Patent number: 9328263
    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.

  • Patent number: 8992714
    Abstract: A method produces adhesive tapes which are adhesive at least on one side, wherein an adhesive tape web, in which the at least one adhesive side is covered by a first liner, is guided into a cutting device in which a total of N individual adhesive tape strips located next to one another are produced in the machine direction from the adhesive tape web. Every other adhesive tape strip is removed from the first liner and is applied to a second liner in each case having a spacing a between the individual adhesive tape strips. The liners are cut between the adhesive tape strips located on the first liner and on the second liner, and the individual adhesive tapes, together with the liner strips, are wound up in a total of X rolls in a form of an Archimedean spiral.
