    摘要: The present invention is directed to a method and apparatus for providing positive control of a printable medium in a printing system such that high speed processing of the printable medium can be achieved without damage to the product (e.g., printed signatures). Exemplary embodiments are directed to a carrier system which contacts (e.g., grips) the printable medium from both sides to provide positive control over the printable medium as it is transported from one area of positive constraint (e.g., a folding mechanism of a folder device) to another area of positive constraint (e.g., transport tapes and/or a signature deceleration device located downstream of the cutting cylinders).

    摘要: An infeed apparatus for a sheet material article trimmer includes a pusher element for moving a sheet material article to be trimmed on a front table of the trimmer and into engagement with a backstop of the front table. The pusher element is moved by a driver which moves the pusher element at the same speed as the front table for a period of time with the pusher element in engagement with a back edge portion of the sheet material article and the backstop in engagement with a front edge portion of the sheet material article. The period of time is at least as long as the time required for the front clamp to move through a distance corresponding to the difference in thickness between the thinnest sheet material article and the thickest sheet material article to grip the sheet material article against the front table.

    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: A stream of signatures is delivered by a conveyer belt to an angled conveyer. The angled conveyor grips a set of signatures from the stream. The gripped set of signatures is transported by the angled conveyer to a third conveyer belt, and deposited on the third conveyer belt. By transporting the set of signatures at an angle, a lateral offset between the individual signatures within the set of signatures is created. A diverter on the third conveyer belt grips the laterally offset signatures, separating the signatures into substreams.

    摘要: The present invention is directed to providing a method and apparatus for diverting and separating sheets of printable material, such as signatures severed from a web, in a cost effective, efficient manner which does not create the potential for damage to the signatures or jamming of the press. Exemplary embodiments can implement a signature diversion and separating in a single step, without reorienting the signatures. Thus, for example, where the signatures include a folded edge, the orientation of that folded edge can be maintained throughout the diverting and separating process.
