Abstract: A digital printing system includes intermediate transfer member (ITM) having multiple layers and markers engraved in layers at marking locations along ITM, to receive printing fluid to form image, sensing assemblies disposed at predefined locations relative to ITM, and produce signals indicative of markers positions, continuous target substrate having opposing first and second surfaces, to engage with ITM at engagement point for receiving image from ITM, at engagement point, the ITM moved at first velocity and the continuous target substrate moved at second velocity, first drum to rotate at first direction and first rotational velocity to move ITM at the first velocity, and second drum to rotate at second direction and at second rotational velocity to move continuous target substrate at second velocity, and processor to engage and disengage between ITM and continuous target substrate at engagement point by displacing one or both of the first and second drums.

Abstract: A digital printing system includes an intermediate transfer member (ITM), to receive a printing fluid to form an image, a continuous target substrate having opposing first surface and second surface, a light source to illuminate the first surface, and an image sensor to image at least a portion of the light transmitted through the target substrate to the second surface, and a processor. The target substrate configured to engage with the ITM at an engagement point for receiving the image from the ITM, and at the engagement point, the ITM is configured to move at a first velocity and the target substrate is configured to move at a second velocity. The processor is configured to produce a digital image based on the electrical signals, and to estimate, based on the digital image, at least a distortion in the image.

Abstract: A printing or embossing unit has at least two cylinders (1, 2). Of the latter, one working cylinder (1) carries at least one printing or embossing stencil (14) on its circumference, in order to emboss or to print, with the aid of the said at least one printing or embossing stencil (14), a web (5) made from a flat material which is conveyed between the said working cylinder and a back-pressure cylinder (2). The embossing stencil (14) extends in each case only over part of the circumference of the working cylinder (1) and is held on the working cylinder (1) with the aid of a fastening device (12, 13, 15). The working cylinder (1) is provided in its interior with a heating device. The fastening device (12, 13, 15) has at least one clamping ring (15) which acts on the circumferential edge (16) of the printing or embossing stencil (14) and clamps against the working cylinder (1).

Abstract: Method and apparatus for checking the quality of blanks processed with a machine processing blanks of at least a certain type, comprising: carrying out a registering for said possible blank types, feeding a register parameter (n) defining a required number of blanks per pile, loading a pile of blanks into a device, conveying the blanks of the pile throughout a registering area ensuring the scanning of the printing and/or diecutting quality of said blanks, defining which type the registered blank is the better related, stripping the blank if it has printing and/or diecutting defects, and piling up the registered blanks that were not stripped so as to pile up a new pile until it comprises n blanks, and repeating the steps, and apparatus for the foregoing.

Abstract: A method for tightening an embossing plate ring on a chuck of a rotary embossing press, wherein the chuck is intended to be connected to a heater for leading the embossing plate ring to a working temperature. Between the chuck and the embossing plate ring is a split transmission ring made of a material having an expansion coefficient which is higher than that of materials used for the chuck and the embossing plate ring to cause the blocking of the embossing plate ring onto the chuck at the working temperature of the embossing plate ring.

Abstract: A rotary press to lay patterns of a material on a strip material comprises a working cylinder bearing embossing plates of the patterns of the aforesaid material to be laid and an opposed anvil cylinder. The working cylinder is rotated. A heater for the working cylinder. A device to exert a defined prestress between the working cylinder and the anvil cylinder. Ball-bearings between the anvil cylinder and its shaft. A device adjusts the space between the working cylinder and the anvil cylinder, independent of the device to exert the defined prestress.

Abstract: A rotary press to print patterns on support strips includes a drive for driving the support strip lengthwise at a defined speed; a supply for strip material of the patterns to be applied to the strip located laterally to the lengthwise drive and direction of the support strip; a transfer device for transferring the patterns from the strip material to defined locations on the strip; another drive for driving the strip material through the transfer device intermittently with the defined speed of the support strip. Strip material reorientation elements are arranged along the path of the strip material to modify its direction from transverse to the support strip to the same direction thereof and to deliver the support strip material and the support strip to a transfer device where transfer occurs. Various length and speed controls associated with the strip material deliver the same to the transfer section at a selected speed.
