    摘要: A sheet flipping device comprising: a flipping element rotatably disposed adjacent to a sheet receiving plane and having, in its outer periphery, at least two insertion slots for insertion of a respective leading edge of a sheet to be flipped; a sheet transport device configured for feeding sheets with their respective leading edges into the insertion slots; and a controller configured to control the sheet transport device and a rotary drive (54) for the flipping element such that each sheet the leading edge of which has been inserted into one of the insertion slots is temporarily restrained while the transport mechanism continues to feed the sheet, so that the sheet flips over, and the sheet is then dropped onto the receiving plane, wherein each insertion slot has a mouth defined between a peripheral surface of the flipping element and a flexible finger that extends tangentially from said peripheral surface, the controller is configured to move one of the insertion slots into a sheet receiving position regardless of whether or not a trailing edge of a preceding sheet has left the sheet transport device, and the flexible finger has sufficient flexibility to be deflected by a sheet which has its trailing edge still held in the sheet transport device.

    摘要: A sheet ejection device comprises an ejection roller pair (20) which ejects a sheet by a pressure contact portion (N) in which a first roller (21) and a second roller (22) are in pressure contact with each other. In the first roller (21), protrusions (41) that protrude in a roller diameter direction in order to push the back end of the sheet ejected with the rotation of the first roller (21) are formed. The protrusions (41) are provided in a flange (45) at a predetermined distance from the peripheral end (43a) of a cylindrical portion (42) of the first roller (21) in a sheet width direction. The distance from the center of rotation of the flange (45) to the front end (41c) of each of the protrusions (41) is equal to or less than the radius of the cylindrical portion (42).

    摘要: An apparatus for conveying sheets from a printing machine to a stack has highly rigid gripper bars that can be produced with relatively little expense, and the gripper assembly permits great flexibility in the use of the apparatus. The apparatus has at least one gripper bar carrying one or more grippers which, during the conveyance, holds a sheet at its edge between a gripper finger and a gripper pad. Endless chains move the gripper bar on a path between a cylinder belonging to the machine and the stack. An actuating mechanism opens and closes the gripper as a sheet is picked up from the cylinder and as it is allowed to fall onto the stack. In the opened state, the gripper finger is located below a path described by the upper edge of the gripper pad.

    摘要: A positive control signature transferring assembly, for use in a lower folder, transports and diverts signatures under positive control. The assembly has a first positive control deceleration device having grippers for transporting some of the signatures of a stream of signatures to a first delivery stream. The assembly has a gripper cylinder containing a plurality of grippers for gripping a leading edge and a trailing edge of each of the remaining signatures in the signature stream for transporting the signatures on the gripper cylinder. A second positive control deceleration device has grippers for transporting the remaining signatures released by the gripper cylinder to a second delivery stream. In this manner, the signatures are positively controlled at all times and alignment and fixed pitch errors are significantly reduced.

    摘要: The conveying device exhibits a plurality of clamps which are each articulated, via a carrying arm and a linking member, on rotational elements. The pivot position of the carrying arm is controlled by a first slotted-guide path and, separately from this, the position of the linking member is controlled by a second slotted-guide path. This permits pivoting of the clamps even independently of the movement of the carrying arms. The clamps can thus be controlled in an optimum manner for the respective purpose. In particular, it is possible, with constant speed of the rotational elements, to change the speed of the clamps and, at the same time, to control the direction of the clamps independently.

    摘要: A device for slowing down signatures being transported in a folding machine is provided. The device provides a plurality of rotary grippers which positively grip signatures exiting a tape conveyor system in the folding machine traveling at a high velocity. A deceleration drum is also provided for slowing down the signatures through a smooth velocity profile. The deceleration drum has a plurality of pivot arms pivotally mounted on a pivot disc rotating about a first axis, the pivot arms being connected to a control disc by a control link, the control disc rotating about a second axis parallel to, and offset from, the first axis. The rotary grippers are attached to outward ends of the pivot arms. The rotary grippers grip the leading edges of the signatures as they exit the tape conveyor system while the trailing edges are still being controlled by the tape conveyor device. The deceleration drum may alternatively be constructed of a cam and linkage system in place of the pivot arm/pivot disc and control link/control disc mechanism.

    摘要: A vacuum assisted sheet transfer assembly has an array of support bars which support the unprinted side of a freshly printed sheet along a sheet transfer path. The support bars overlie the airflow inlet of a manifold housing, with the longitudinal axis of each support bar extending across the sheet transfer path. The support bars provide smooth surfaces for engaging and supporting the unprinted side of the sheet material as it is pulled along the transfer path while simultaneously limiting the flow of inlet air through elongated inlet apertures. As air is drawn through the inlet apertures, the unprinted side of the sheet is sucked into engagement with the support bars as it moves along the sheet transfer path. The sheet transfer assembly eliminates the need for conventional skeleton wheels and the like. Marking, smearing and smudging are prevented since the printed side of the sheet is not handled or contacted in any way as the sheet is conveyed along the sheet transfer path.
