  • Patent number: 6533207
    Abstract: A method for producing a roll from printed products in a winding operation includes winding the printed products with winding tape onto a winding core; driving a winding rug with a first drive, wherein the winding rug is arranged on the underside of the winding core and fitted against the winding core for rotating the winding core; driving a winding tape supply with a second drive, wherein the winding tape is unwound from the winding tape supply; and maintaining a predetermined tape tension during the winding operation. Maintaining the predetermined tape tension includes measuring speed and distance with measurement devices at the first and second drives to obtain measured values, computing the diameter of the winding tape supply with the measured values, and regulating a rotational moment with the computed diameter of the winding tape supply to maintain the tension.

  • Patent number: 4842213
    Abstract: A catching ribbon for catching and holding a thread on a thread support, such as a thread wind-up bobbin rotating at high speed, is provided at its circumference with catching elements. These catching elements comprise thread engaging portions, such as hooks. The space between two thread engaging portions of two immediately adjacent catching elements are positioned to allow a single thread passage therebetween but precluding thread retro-movement. The catching elements comprise miniature pins provided with heads configured to form the thread engaging portions, such as semi-circular heads or anchor-like heads similar to kedge anchors. Catching elements with a single thread engaging portion, such as a single hook, also may be provided. Successive rows of the single-hook catching elements or successive rows of the double-hook catching elements may be arranged in staggered relationship.
