  • Patent number: 6159557
    Abstract: The process for producing pressure-sensitive adhesive tapes comprises the steps ofclamping a tube strip of a tube skin filled with a pressure-sensitive adhesive composition into an apparatus comprising a tubular appliance,passing the tube strip through the tubular appliance while opening the tube skin longitudinally to form a tape,separating the tape from the pressure-sensitive adhesive composition in such a way that some of the pressure-sensitive adhesive composition remains as a film on the tape,causing the separated pressure-sensitive adhesive composition to exit the apparatus by way of a discharge aperture, andwinding up the tape separated from the pressure-sensitive adhesive composition, with the pressure-sensitive adhesive film that has remained thereon, as a pressure-sensitive adhesive tape.
