  • Patent number: 8882098
    Abstract: An interfolder separator apparatus and method utilize a pair of count fingers that are movable longitudinally along and transversely to a stream of folded sheets, for temporarily supporting each successive pack formed by the separator and then releasing each successive pack when partly completed to alternating build fingers, so that the operation of separating successive packs from one another is performed separately from the operations of completing the build of each pack and transporting the completed packs to downstream operations. The count fingers may be mounted to pivot about axes that are movable longitudinally along and transversely to the stream of sheets. A first or last panel of the completed pack may also be folded back partly upon itself, after the partly completed pack is released by the count fingers. Some or all of the fingers may be spring loaded and automatically resettable for clearing jams.

  • Patent number: 8240652
    Abstract: A method for separating two consecutive interfolded sheets, during the production of packages of paper products, even if there is present at least one tear-off line or “tab bond”. The sheets are fed in an interfolded way from interfolding rollers on a table by means of suitable folding arms. At a predetermined height of the stack a first plurality of separators, arranged along the length of the stack and at opposite sides with respect to it, are inserted in the same stack. This introduction divides the formed stack from the growing stack. Between the separators and the table a side of a sheet stretching board is introduced. The formed stack is then arranged between the table and the sheet stretching board. These are lowered vertically and move away from each other autonomously from the separators up to cause the disengagement of the growing stack from the formed stack.

  • Patent number: 8243324
    Abstract: When a user sets, from a user interface window using a bookbinding application, instructions of dividing a document into a plurality of parts and stapling each part of the document, a printer driver generates one job in which the staple attribute of a binder corresponding to each part is set to “ON” or “OFF”, and issues the job for a printer. With this operation, the user can perform staple designation to an arbitrary part of the document, and can realize a plurality of staple processes in one print job.

  • Patent number: 7997570
    Abstract: The sheets are supplied interfolded by two folding rollers, on a table on which they are piled up forming a stack. When the stack achieves a predetermined height a first plurality of separators and a second plurality of separators, arranged for all the length of the stack and from opposite sides are inserted into the stack to provide the disengagement of the stack already formed from a stack being formed, leaving between them of a wing of sheet hanging. The stack formed is then withdrawn quickly from the stack being formed by means of a table, which translates vertically, and is subject to a blow of air for stretching a possible last sheet. Then, the stack formed is left on a longitudinal conveyor belt located underneath. At the same time, a sheet stretching board moves under the stack of interfolded sheets, for all its length, for provisional support thereof and for stretching completely the wing hanging from the stack being formed with a portion of wing that exceeds sheet stretching board.

  • Patent number: 7442157
    Abstract: An interfolding machine for sheet material for making a stack of interfolded sheets includes at least one web of material to interfold that is cut into sheets of predetermined length and rolls for partially overlapping the sheets in order to form an overlapped portion between two consecutive sheets. Interfolding rolls are also provided, adapted to produce the stack, as well as a conveyor adapted to convey the partially overlapped sheets in a zone set between the roll and the interfolding rolls. Further, the overlapping portion of the sheets is maintained constant through a plurality of belts and guides facing the belts so that between the belts and the respective guides a channel is formed for conveying the partially overlapped sheets.

  • Patent number: 7402130
    Abstract: This invention provides a system and method for separating, folding, stacking and transporting a continuous web that allows stacks of web that are relatively large (four-feet-high or more) to be generated at high speed directly beneath the folding mechanism and to be transferred as complete, discrete stacks to downstream locations and stack utilization devices without interrupting the ongoing, upstream stack-folding and stack-formation process. A zigzag folded web passes by a pair of opposing front and rear compression plate assemblies, with fingers that are extended to selectively project into the folding area, onto a stack supported by a vertically moving supporting mechanism. The supporting mechanism cycles between an ever-lower position in which upper, loose pages of the folded web pass by plate fingers (when retracted) and an upper position in which the stack engages and presses upwardly against the now-extended plate fingers to compress the stack.

    Abstract: A package of strip material includes a plurality of stacks of the strip side by side where each strip forms a stacked fan folded supply of the strip which is spliced to or arranged so that it can be subsequently spliced to a next adjacent strip for supply of a continuous strip from the package. The side by side stacks are simultaneously built up from the bottom by moving a carriage back and forth below a stationary bottom surface of the stacks with the strips supplied side by side through a slot in the carriage. The stacks are supported side by side as they are built up by rigid side walls of a chute or of a box into which the package is to be packaged for transportation. The tails are supported or arranged so that they are ready for splicing when the package is completed an before transportation. The packaging material can be an evacuated bag or a rigid box.

  • Publication number: 20010048189
    Abstract: A separator finger apparatus and method for insertion of a separation finger into and removal from a stream of web product. The unique motion provided by the elements making up the separation finger apparatus permits the separation finger to be mounted close to folding rolls (from which the web product issues) with reduced separation finger-to-folding roll interference. Specifically, the separation finger is manipulated to rotate and translate simultaneously as it is inserted into or removed from the stream of web product. The elements creating the separation finger motion are preferably a pivot arm mounted for rotation about a first axis and a translation member mounted for rotation about a second axis. The pivot arm is preferably rotatably coupled to the separation finger at a third axis. The separation finger is preferably coupled to the translation member for translational or sliding motion therealong.
