| 20090111674 | CREASING-FOLDING MACHINE FOR PRODUCING PAPER AND BOOKBINDING ARTICLES - A creasing-folding machine, for producing paper and bookbinding articles, has a feed unit, for feeding sheets along a feed path, a creasing unit, and a folding unit in series with one another; the creasing unit has at least one creasing roller positioned with its axis perpendicular to the feed path and having, on its lateral surface, a creasing blade extending crosswise to the feed path, and a pressure roller which cooperates with an opposite face of each sheet to the creasing roller; the creasing unit is interposed between the feed unit and the folding unit to perform continuous transverse creasing operations upstream from the folding unit. | 04-30-2009 |
| 20110039677 | Pleated paper towel stack and method - A continuous length of pleated paper towel having a leading end and a trailing end. The continuous length of pleated paper towel including a connection at one of the leading end and trailing end that attaches to another continuous length of pleated paper towel to permit uninterrupted dispensing operation of paper towel. | 02-17-2011 |
| 20130184138 | METHOD AND APPARATUS FOR FORMING FAN-FOLDED WEB OF LABELS WITH IMPROVED REGISTRATION - An off line apparatus for converting a rolled web into a fan-fold web and method of fan folding a web is described. The apparatus has a creasing station capable of receiving the web at a feed rate. The creasing station has a first die roller, wherein the first die roller comprises a first blade and a first cushion, and a second die roller. A coupling mechanism synchronizes rotation of the rollers such that the first blade engages the second cushion and the second blade engages the first cushion during one each rotation. A reader determines the location of a gap between the labels. A controller receives the location of the gap from said reader and communication with a drive mechanism to adjust the rotation rate such that the first blade and the second cushion engage. | 07-18-2013 |
| 20140378288 | AUTOMATED MACHINE TO FOLD IN A ZIGZAG MANNER AND STACK A CREASED TAPE MADE OF A SUFFICIENTLY RIGID MATERIAL - Automated machine to fold in a zigzag manner and stack a creased tape made of a sufficiently rigid material and provided with a plurality of transverse creasings equidistant with respect to each other, comprising feed means suitable to feed the creased tape in a determinate direction of feed toward a folding device of the rotary type suitable to fold it in a zigzag manner and to convey it toward collection means. The folding device comprises four parallel pairs of main arms, having the same length and disposed in a cross, which rotate in a direction of rotation consistent with the direction of feed of the creased tape around a central axis of rotation perpendicular to the latter, four corresponding parallel pairs of secondary arms, pivoted to the peripheral ends of the main arms, toward the inside thereof and rotatable in an opposite direction to the latter, and four folding rods pivoted to the peripheral ends of the secondary arms, so that each of the four folding rods is suitable to describe in space a substantially elliptical trajectory. The folding rods are suitable to intercept the creased tape in correspondence to every two of the transverse creasings. The major axis of the trajectory is substantially horizontal and the central stacking axis of the collection means is substantially vertical and parallel to the minor axis of the trajectory. | 12-25-2014 |
| 20150360900 | FOLDING MACHINE FOR LARGE-FORMAT DOCUMENTS - A sheet-folding machine has a housing having an off-line intake slot and, offset therefrom, an on-line intake slot, a manual sheet-input table on the housing juxtaposed with the off-line intake slot for feeding of a sheet manually into the off-line intake slot, and an automatic sheet feeder juxtaposed with the on-line intake slot and capable of cooperating with a sheet-processing device to receive a sheet therefrom and feed it into the on-line intake slot. Respective off-line and on-line guide chutes in the housing each have an upstream end at the respective slot and a downstream end. The downstream ends meet at an intersection. A roller-type folding unit in the housing receives a sheet to be folded at the intersection and folds it. | 12-17-2015 |

| 20090029839 | Soft Roll Material-Translation Device - The present invention relates to a soft roll material-translating device for the mechanical apparatus of machining and cutting after severing. The existing pillow type of automatic packing machine can only pack produces using one single roll of film, so the work efficiency is low. Consequently, the present invention aims at improving the work efficiency and it adopts following technical solutions: the soft roll material-translating device includes a frame ( | 01-29-2009 |
| 20100261594 | RESILIENT TUCKER ELEMENT FOR INTERFOLDER FOLDING ROLLS - A method and apparatus are provided for facilitating folding of material fed through a nip between two folding rolls having a tucker on one roll and a corresponding gripper on the other roll, by using a resilient tucker element having a tip that is moveable from a neutral position thereof, through elastic deformation of at least a portion of a body of the tucker element, for directing a portion of the material into the gripper. The resilient tucker element may have a tucker body formed at least partially of elastically resilient material fixedly attached at a proximal end thereof to the other roll. A portion of a distal end of the resilient tucker element may be wedge-like and have vacuum ports extending at least partially into the wedge-like portion, for securing an end of a sheet of material being fed through the nip between the folding rolls. | 10-14-2010 |
| 20140121092 | Z-FOLDING THREE-DIMENSIONAL-STRUCTURE FORMER - A device for producing a three-dimensional structure from a receiver includes a deposition unit that deposits toner on two surfaces of the receiver. That unit is controlled by a controller to produce a toner pattern on the first surface of the receiver. A softening device softens the toner. An automatic z-fold system makes a z-folded stack of separate portions of a length of the receiver, each portion being joined to at least one other portion in the z-folded stack by at least one of the z-folds. The z-fold system brings two separate portions of the same surface of the receiver into contact, at least one portion carrying softened toner. | 05-01-2014 |
