  • Publication number: 20230078411
    Abstract: The disclosure relates to a winding device for winding a rope onto a rope drum rotatable about a rotation axis. The winding device includes a rope guide for feeding the rope to the rope drum. The rope guide has a pivoting arm having a longitudinal axis and has a deflection element. The pivoting arm is pivotable about a pivot axis. The deflection element is disposed on the pivoting arm. The winding device is conceived such that the rope when being wound onto the rope drum passes the pivoting arm before the deflection element. The rope guide includes a delimitation element. The delimitation element is disposed such that a pivoting movement of the pivoting arm about the pivot axis is limited to a critical angular range (?). The deflection element is tiltable about a tilting axis. The tilting axis extends along the longitudinal axis of the pivoting arm.

  • Patent number: 10926980
    Abstract: The invention relates to a drive device (1) for the spool (6) of a winch. The drive device (1) comprises a drive motor (2) having a drive shaft (5), a transmission (3) and an output shaft (4) that drives a spool (6). The transmission has a first drive connection (10) between the drive shaft (5) of the drive motor (2) and the output shaft (4) to the spool (6). The first drive connection (10) drives the output shaft (4) over a first rotational speed range (DB1) in a first gear. According to the invention, a second drive connection (30) is provided between the drive motor (2) and the output shaft (4), wherein the second drive connection (30) drives the output shaft (4) over a second rotational speed range (DB2) in a second gear. The second drive connection (30) is designed to be separate from the first drive connection (10) as a parallel drive path, and is driven by the drive motor (2) together with the first drive connection (10).

  • Publication number: 20100288147
    Abstract: An apparatus for a rotary offset printing press includes a print cylinder having a radially inward extending groove and a rubber blanket having a main section coupled to the print cylinder. The rubber blanket includes at least first, second and third layers in the main section. The first layer is a self-adhering layer which faces the print cylinder and is adapted to attach the rubber blanket to the print cylinder. The second and third layers are a support layer and a cover layer, respectively, which both face away from the print cylinder. The rubber blanket has a leading end section, as seen in a production direction of the print cylinder, and a trailing end section, as seen in the production direction of the print cylinder. The end sections directly adjoin the main section and at least the leading end section of the rubber blanket is inserted into the groove of the print cylinder.

  • Publication number: 20090199732
    Abstract: A cylinder for a printing unit of a printing machine includes a hollow support shaft with first and second tensioning elements arranged thereon at a distance to each other. A replaceable printing sleeve is positioned on the support shaft. First and second force transfer elements respectively cooperate with the first and the second tensioning element for clamping down and releasing the printing sleeve. An operating mechanism is arranged on the inside of the hollow support shaft and is operatively connected to the two force transfer elements. The operating mechanism includes at least one energy-storage element for tightening and releasing the two tensioning elements.
