  • Two-part cylinder for a folder in a rotary printing machine
    Patent number: 6726616
    Abstract: The cylinder includes first and second cylinder parts which are designed to be rotatable in relation to one another in the circumferential direction and are fitted with respective first and second operating elements for acting on a foldable product. The first cylinder part is mounted non-rotatably on a shaft and of the second cylinder part is mounted on the shaft rotatably in the circumferential direction. The shaft is mounted at one end, fixed axially, in a side wall in a bearing designed as a fixed bearing. The second cylinder part is mounted separately, with a spacing (A) from the first cylinder part, in a second fixed bearing which is independent of the first bearing.

  • Folding cylinder
    Patent number: 5782464
    Abstract: A folding cylinder for a folding apparatus of a rotary printing press having displaceable mechanisms which are connected with at least one spindle which is arranged in the folding cylinder, spaced radially from its shaft and can be turned by an adjustment spindle arranged in a coaxial bore in the shaft. The adjustment spindle is secured against rotation with respect to the shaft but is axially displaceable in its bore, and, axially spaced, is firmly attached to a pull which has two courses that extend towards each other, pass over a guide pulley, arranged in a radial opening of the bore to a drive disk which is fastened on the spindle and wrapped by the pull chain.
