Method and device for initial alignment of embossing cylinders of rotary multicolor printing presses

Patent application title: Method and device for initial alignment of embossing cylinders of multi-color printing presses of patents Patent applicant Bob Stowe Co., Ltd. Principal applicant address Inventor of Lausanne, Switzerland Inventor L. Garn Caterino; A Royle Application (Patent) No. 200510070151.5 Application Date 2005.04.30 Award Date Approval Notice No. 1693073 Validation announcement date 2005.11.09 Instruction CD-ROM D0545 Main classification number B41F13/18 Classification No. B41F13/18; B41F13/08 Original Application No. 2004.5.5 CH 00801/04 Abstract According to this method, an angular alignment mark (CR) is set on each embossing cylinder (C1...Cn) and its position relative to a zero base is measured. The embossed position angle printing (RM, CM) feature is associated with each embossing cylinder (C1...Cn). The data of the task to be performed is stored, and by determining the web length separating the two printing points of two successive embossing cylinders (C1...Cn), dividing the length by the peripheral length of the phase embossing cylinder and using the same The calculated margins are used to determine the angular index, so that the corresponding angular displacement of the embossing cylinders (C2...Cn) is indexed relative to a reference cylinder (C1) according to the task. The rollers (C1...Cn) are then rotated to their indexed position and then disengaged, and all the adjusted rollers (C1...Cn) are simultaneously reconnected to the driveline. Sovereignty item 1. A method of initial adjustment of the circumferential alignment of embossing cylinders (C1...Cn) of successive printing units of a multi-color printing press of a rotary multi-color printing press, with the aid of a corresponding clutch. (CL) are connected to the same drive line (MS), according to which an angular alignment mark is associated with each cylinder (C1...Cn) and these angular positions are measured and stored with respect to a zero reference, characterized in that The data of the task to be executed is stored and by determining the web length of two printing points separating the two printing units of two successive embossing cylinders (C1...Cn) relative to the determined task, the length is divided by the setting The circumferential length of the embossing cylinder at the downstream of the direction of travel of the web, and the angular index is determined using the margin calculated by this division so that the embossing cylinder is indexed against a reference cylinder (C1) according to the task. Corresponding angular displacement of (C2...Cn), then successively rotate each roller (C1...Cn) to its indexed position and fix it, and then release it from the driveline (MS) and all The adjusted rollers (C1...Cn) are simultaneously reconnected to the driveline.
