    摘要: An axially shiftable sheet gripper assembly includes cooperating gripper fingers and gripper abutment surfaces mounted on an axially slidable carriage. The carriage is located in a groove in a sheet transfer drum and carries a control roller at one end. The control roller rides on a control surface of a pivotable control disk. This control disk is movable toward and away from a side face of the sheet transfer drum to regulate the axial movement of the sheet transfer mechanism carriage.

    摘要: A sheet fed rotary printing press is switchable between recto and recto and verso printing. A sheet transfer drum carries sheet leading and trailing edge grippers which are shiftable with respect to each other by use of a disengagable clutch. When the sheet transfer drum is placed in the recto position, stops that are carried in the leading and trailing edge grippers abut each other.

    摘要: A shift-over device for controlling the turning drum grippers of a rotary sheet printing press optionally changeable for one-side printing or two-side printing and having a relatively rotatable gripper opening cam and an axially movable gripper turning cam includes a rotatable switching shaft carrying a stop arm with adjustable stops mounted on the press frame for engaging the stop arm and limiting the rotation of the switching shaft in opposite directions. A first crank arm is secured to the switching shaft and carries a lash lever coupled to the gripper opening cam for relatively rotating it incident to oscillations of the switching shaft. A second crank arm is secured to the switching shaft and coupled to a push arm having face cams engageable with push rods connected to the gripper turning cam for axially shifting it incident to oscillations of the switching shaft. In the preferred embodiment, a pneumatic cylinder is connected to a drive crank secured to the switching shaft and a source of pneumatic pressure with a control valve interposed between the source and the pneumatic cylinder is provided for actuating the cylinder to oscillate the switching shaft and simultaneously rotate the gripper opening cam and axially shift the gripper turning cam.

    摘要: The invention relates to a process for the production of structured retaining areas on sheet grippers, sheet gripper supports or similar gripper facilities for machines for handling and processing sheets by the formation of a non-etchable dot structure on the base member and the subsequent etching out of intervening areas. To provide structured retaining areas having a smoothly shaped surface, the dot structure is produced by screen printing or pressure pad printing and after the etching-out of unprinted areas, a hard smoothing coating, preferably of chromium or ceramic, is applied to the structural retaining area.

    摘要: A coupling for a sheet fed rotary printing machine utilizes a sheet transfer drum having a pair of interfitting toothed drive wheels. The two toothed drive wheels are joined to each other by a friction fit that is applied through a plurality of elongated cylinder screws. These screws are tensioned by a group of radially extending, pivotably mounted actuating levers. A pneumatic cylinder and piston rod assembly is used to release the tensioning force applied to the cylinder screws to thus allow the two toothed wheels and hence the sheet transport component of the sheet transfer drum to which they are attached by be rotated relative to one another. Such relative rotation is accomplished by locking one printing couple and driving the other.

    摘要: A coupling for a sheet transfer drum in a sheet fed rotary printing machine facilitates phase or spacing adjustments between two printing couples. A toothed wheel is secured to a journal portion of a sheet transfer drum body. The toothed wheel carries a toothed ring on a support surface with the toothed ring being movable with respect to the toothed wheel through the use of a high pressure fluid injection interference fit. Movement of the toothed ring with respect to the toothed wheel by rotation of one of the printing couples with respect to the other effects a change in position of the sheet leading edge engaging gripper row carried by the sheet transfer drum periphery with respect to the sheet trailing edge engaging holding bar carried by the support segments connected to the toothed ring.
