101415100 | FLEXIBLE-SHEET-SECURING DEVICES | 9 |
20080196614 | CLAMPING AND RELEASING FLEXIBLE PLATES TO AND FROM AN IMAGING CYLINDER - A method for fastening plates onto an imaging cylinder, and an apparatus that includes one or more clamping devices. Each clamping device includes a clamping bar and an air hose that when inflalted lifts the clamping bar so that one end of a plate can be placed between the surface of the clyinder. The imaging clyinder includes magnetized elements on or close to the surface. A metal bar is placed on the plate near the magnetized element to hold the plate that is already clamped at one end. The apparatus is operative to fasten flexible plates, metal back plates and non metal back plates onto an imaging cylinder. Embodiments of the apparatus can work with plates of different material, thickness and format onto an image cylinder. | 08-21-2008 |
20090120314 | Holding Apparatus - The present invention relates to a holding apparatus which is made to hold a flexible plate wound on a circumferential surface of a holder and more particularly to a holding apparatus suitable for use in the retention of a plate on a circumferential surface of a sleeve of a plate cylinder of a printing machine. A holding apparatus | 05-14-2009 |
20090173247 | PRINTING PRESS CYLINDER - A printing press cylinder is disclosed. The cylinder includes a lock-up channel extending in an axial direction of the cylinder, where a clamping piece is accommodated in the lock-up channel to clamp a plate on a surface area of the printing press cylinder. The clamping piece includes first feed slants and second feed slants. Projections of the leading edge of a to-be-clamped plate are co-operable with the first feed slants and projections of the trailing edge of a to-be-clamped plate are co-operable with the second feed slants such that the leading edge of the to-be-clamped plate is clampable in a self-centering manner between the clamping piece and a leading channel wall of the lock-up channel and the trailing edge of the to-be-clamped plate is clampable in a self-centering manner between the clamping piece and a trailing channel wall of the lock-up channel. | 07-09-2009 |
20090205523 | PLATE INSERTING APPARATUS - A plate inserting apparatus includes a plate cylinder, press roller, and braking unit. A plate is to be mounted on the outer surface of the plate cylinder. The press roller is rotatably supported to oppose the outer surface of the plate cylinder, and inserts the leading edge bent portion of the plate, supplied to the plate cylinder upon rotation of the plate cylinder, into a groove portion formed in the outer surface of the plate cylinder. The braking unit is arranged in a plate storing portion for storing the plate supplied to the plate cylinder, and brakes the plate with the leading edge bent portion inserted in the groove portion of the plate cylinder. | 08-20-2009 |
20090288570 | Method For Handling Printing Plates - Exposed printing plates are bent in the area of a bending device to form a leading end and a trailing end. Each exposed and bent printing plate is grasped in the area of the bending device at the leading end or at the trailing end of the printing plate by means of a gripping bar and transferred together with the gripping bar to a transporting device. The transporting device transports the printing plate together with the gripping bar toward a printing press, where the printing plate is removed together with the gripping bar from the transporting device in the area of the printing press. While grasped by the gripping bar, the plate is transferred to a form cylinder of a printing mechanism of the printing press. | 11-26-2009 |
20100199871 | Means for Attaching a Printing Plate to a Printing Cylinder - A means for removably attaching a printing plate to a printing cylinder using an intermediate sheet of photopolymer. The tack of the photopolymer is used to attach itself to the printing cylinder and to attach the printing plate to it. Microspheres are incorporated into the photopolymer sheet to provide a cushioning effect when in use on the printing press. | 08-12-2010 |
20110203469 | CONVERSION OF PRINTING PLATE CYLINDERS FOR INCREASED PRINTING LENGTH - Devices for converting a printing plate cylinder from a first configuration that provides a first printable length to a second configuration that provides a second printable length greater than the first printable length | 08-25-2011 |
20120272848 | METHOD AND APPARATUS FOR MOUNTING A PRINTING PLATE - A method and apparatus for mounting a printing plate onto a printing cylinder, wherein the printing plate includes a first registration mark and a second registration mark centrally located along opposing edges thereof. The apparatus includes an optical system to transmit images of the registration marks to a user interface, wherein a user selects a desired location point location of each of the registration marks displayed on the user interface to facilitate an alignment of the printing plate in respect of a central axis of the printing cylinder. | 11-01-2012 |
20140230673 | BLANKET TENSIONING DEVICE - A blanket tensioning device for an image transfer medium (ITM) cylinder includes two elongated blanket holders. A long dimension of each blanket holder is substantially parallel to a long dimension of the other. At least a part of at least one of the blanket holders is moveable toward or away from the other blanket holder. The device includes at least one spring that, is longitudinally arranged with respect to the long dimension and a transmission for converting a force that is exerted by the spring to a transverse force that is applied to the moveable part. When the device is installed on the cylinder with the long dimension being oriented substantially parallel to an axis of the cylinder, and when a blanket is wrapped around the cylinder with each of opposite ends of the blanket being held by each of the blanket holders substantially parallel to the cylinder axis, the applied transverse force tensions the blanket. | 08-21-2014 |
