Abstract: A cutter and a printer having a cutter prevent the paper pieces cut off by the cutter from collecting at the paper exit from which the cut-off pieces are discharged. A stage surface 40defines the bottom edge 5a of the paper exit 5. A sloped guide surface 41 is formed sloping down from the downstream side of the stage surface 40. A first side wall 42 determines where one side of the width of the paper passes over the stage surface 40 and the sloped guide surface 41. A second side wall 43 determines where the other side of the width of the paper passes. A protrusion 47 is formed on the first side wall 42 protruding toward the second side wall 43.When label paper 11 is cut, the cut-off portion 11c is deposited on the stage surface 40 covering the top of the protrusion 47. As a result, the cut-off portion 11c is made unstable by the protrusion 47 immediately after being deposited on the stage surface 40, and slides down easily.

Abstract: Prior to a mark imaging process executed for the purpose of detecting a position of recognition marks for positioning the substrate and the mask, an optical axis calibration processing process of detecting a horizontal relative position between imaging optical axes, and a surface correction data creation processing process of detecting a local positional deviation of the imaging optical axes, which is caused by the travel of the imaging unit, are executed. Before starting production, a production pre-start precision evaluation process for evaluating a substrate positioning precision is executed by using a verification substrate and a verification mask, and after starting the production, a production post-start precision evaluation process for evaluating a substrate positioning precision after starting the production is executed by using a commercial production substrate and a commercial production mask.

Abstract: The screen printing apparatus includes two screen printers 11A and 11B each including a substrate introduction portion 12 by which a substrate 4 is introduced from the upstream side of the component mounting line 3, a printing portion 13 which performs a screen printing to the introduced substrate 4, a substrate discharge portion 14 by which the substrate 4 subjected to the screen printing is discharged to the downstream side, and a substrate moving stage 15 which receives the introduced substrate 4 so as to position the substrate 4 with respect to the printing portion 13 and to move the substrate 4 subjected to the screen printing to the substrate discharge portion 14. The two substrate introduction portions 12, the two printing portions 13, and the two substrate discharge portions 14 are arranged symmetrically to each other with respect to a perpendicular symmetrical plane S extending in a transportation direction of the substrate 4 in the component mounting line 3, respectively.

Abstract: The present invention relates to a scraper device for a printing machine which comprises a scraper body (20) having longitudinal blades (2) and lateral sealing elements, and having ink inlet and outlet passages (24). The scraper body (20) is supported by a scraper support (10) adjacent to an inking roller of a printing machine, and having ink supply and discharge passages (11) connected to respective ink supply and discharge conduits of an ink circulation device. Positioning and fixing means allow fixing the scraper body (20) to the scraper support (10) in an operating position in which openings (24a) of said ink inlet and outlet passages (24) of the scraper body (20) are in fluid communication with openings (11a) of said ink supply and discharge passages (11) of the scraper support (10).

Abstract: The present invention relates to a reverse offset printing method, and more particularly, to a reverse offset printing method in a partial off type capable of accurately transferring a pattern to a cliche to achieve more precise minute printing by separately performing removal for each shear region of a functional ink even though the pattern is minute.

Abstract: The present invention is directed to an apparatus for applying markings, particularly to springs, that are clean (ink in self contained storage units), allows quick color changes and reduces wasted ink or paint. An application means that does not dry out during short down time periods, keeps up with production rates, and is cost effective.

Abstract: A printing press includes a printing form cylinder, a blanket cylinder, an impression cylinder, an adjusting device for setting a printing pressure between the blanket cylinder and the impression cylinder, a control device for throwing the pressure of the blanket cylinder on and off relative to the impression cylinder and springs for producing bearer ring pressure between bearer rings of the printing form cylinder and bearer rings of the blanket cylinder. The springs are integrated into coupling links and are connected to at least one of the two devices in such a way that, as a result of the actuation of that device, the springs are also adjusted, in order to keep the bearer ring pressure at least substantially constant.

Abstract: A screen printing apparatus in which two printing units are provided in a production line which transports boards from a single board exit position set on a downstream side in a conveyance direction. One printing unit being disposed is available for set-up tasks while the other printing unit is working. Since set-up tasks can be conducted in one printing unit while the other printing unit is working, then it is possible to improve through-put dramatically even in cases where small-volume diverse-component production is carried out in a single lane.

Abstract: With a method for operating a transport system, used in the production of printed products composed of signatures or printed sheets, at least one first conveying belt is provided downstream of a printing press designed for producing the signatures or printed sheets. Further downstream, this conveying belt is divided into at least two individually operating conveying paths, wherein at the end of each of the conveying paths the transported signatures or printed sheets are supplied while positioned straddling and via a continuously operating folding device to at least one intermediate gathering device. For the further transport, the signatures or printed sheets are transferred from the gathering device in a serial, monotonous, intermittent, synchronous or non-synchronous sequence to a main conveying section. The signatures or printed sheets which are combined to form partial book blocks or complete book blocks are then wire-stapled, thread-stitched or bound with adhesive.

Abstract: It is an objective to provide a screen print system and a method for cleaning a mask of the screen print system that enable sufficient cleaning of the mask used for subjecting a cavity substrate to screen printing. A mask contact area R of a paper member 42 is brought into contact with a lower surface of one of convex portions 13t of a first mask 13a, thereby removing paste Pst adhering to the lower surface. Subsequently, the paper member 42 is winded up before the paper member 42 contacts the next convex portion 13t to be subjected to removal of the paste Pst, thereby updating the mask contact area R.
