The other portion (34) of the cushioning pad is preferably a compressed portion, a connecting portion which maintains the geometry of the pillow-like portion, and/or a central portion.Type: GrantFiled: April 16, 1999Date of Patent: January 2, 2001Assignee: Ranpak CorpInventors: Serge H. L. C. Pluymaekers, Mike J. Timmers, Pierre H. G. Kobben

Patent number: 6165116Abstract: A system and method for creating a discontinuity in a stack of interfolded sheets in which folding rolls cooperate to interfold staggered sheets supplied in two streams of sheets, each of which is severed from a web of material. When a desired sheet count is attained, a sheet in one of the streams of sheets is folded onto itself so as to create a discontinuity in one of the streams of sheets. The folded sheet is formed by maintaining a leading portion of the sheet in engagement with a separating one roll while maintaining a trailing portion of the sheet in engagement with another roll, with the two rolls being positioned to form a nip therebetween and rotating in opposite directions.Type: GrantFiled: January 12, 1999Date of Patent: December 26, 2000Assignee: Green Bay Engineering Corp.Inventor: Barton J. White

Patent number: 6080097Abstract: A pair of clutches selectively transmit power to a coining mechanism and to a cut-off mechanism in a paper converting machine. As sheet-like material is advanced through the machine, it is formed into a three dimensional strip of padding by a forming mechanism. Next the strip is coined or otherwise secured to keep its three dimensional shape by a coining mechanism. Thereafter the strip is cut into sections of the desired length by a cut-off mechanism. Advantageously, both the coining mechanism and the cut-off mechanism are powered by a single motor, then are selectively connected to the motor by a pair of clutches. The clutches may be wrap spring clutches, and the clutch controlling power to the cut-off mechanism may be a single revolution clutch.Type: GrantFiled: December 8, 1997Date of Patent: June 27, 2000Assignee: RanPak Corp.Inventors: Richard O. Ratzel, James A. Simmons, Jr

Patent number: 6038974Abstract: A gripper deceleration cross folder device having a rotatably mounted jaw cylinder including a plurality of jaw devices, a rotatably mounted gripper decelerator drum forming a nip with the jaw cylinder, and a plurality of gripper decelerator devices mounted on the gripper decelerator drum, each gripper decelerator for gripping and decelerating one of a plurality of signatures at a time. A respective tucking device corresponding to each of the plurality of gripper decelerator devices for tucking each one of the signatures into a corresponding one of the plurality of jaw devices after the decelerating of the signature so as to fold the signature.Type: GrantFiled: November 5, 1998Date of Patent: March 21, 2000Assignee: Heidelberger Druckmaschinen AGInventor: John S. Richards

Patent number: 6010122Abstract: A method and apparatus is disclosed for producing high page count signatures for printed publications. Signatures with a 96 page count and 128 page count are illustrated and described herein. In either case, the signature is constructed of four sheets of printed sheet materials which are preferably continuous webs of sheet material that are fed to a folding and cutting apparatus. The four sheets or webs are folded in half along a main longitudinal fold line extending in the direction in which the web travels. Preferably, the webs are perforated along the main longitudinal fold line prior to being folded. The webs, after being folded in half, are perforated to create a longitudinally extending hinge. Also, the webs are preferably perforated to create cross fold lines. In the case of the 96 page count signature, the folded webs are divided into thirds by the cross fold lines. The folded webs of the 128 page count signature are divided into fourths by the cross fold lines.Type: GrantFiled: May 16, 1997Date of Patent: January 4, 2000Assignee: Wallace Computer Services, Inc.Inventor: William C. Weber

Patent number: 5921906Abstract: A pinless folder has a hold-down blade in a cut-off cylinder having, together with paper presses, a cut-off knife capable of cutting a web a in its entire width. A folding cylinder contiguous to the cut-off cylinder is provided, in addition to a cutter pad and a gripping jaw, with a gripper board for holding the front end of the web a held down by the hold-down blade. The web a passing between the cut-off cylinder and the folding cylinder is cut in one operation at an even speed. The even-speed, one-stage cutting results in improved quality and a reduced number of component parts.Type: GrantFiled: September 23, 1997Date of Patent: July 13, 1999Assignee: Komori CorporationInventor: Hiroyuki Nagano

Patent number: 5823934Abstract: The automatic trimming machine of the present invention utilizes a conventional web press to print various sizes of postal and insert cards, flyers and coupon books completely on-line. The automatic trimming machine of the present invention includes a device (12) for perforating the paper to define a folding line (14) and a paper folding device (16) for folding the paper along the perforated folding line. A preliminary trimming unit will first trim the left and right sides of the folded paper, including removing the backbone of the folded paper. The severed backone is then removed from the preliminary trimming unit. The top and bottom edges of the paper are then trimmed to the appropriate size prior to the paper being cut into distinct products in a finish trimming unit. The finish trimming unit includes a plurality of adjustable cutting blades to allow for cutting of various sized products.Type: GrantFiled: October 20, 1995Date of Patent: October 20, 1998Inventor: Rock A.
