摘要： A blanket belt for use in a printing machine is produced through a producing step including a reinforcement member setting step P1 of setting a reinforcement member 3 onto a mold having teeth shape at an outer circumferential surface thereof, a rubber sheet setting step P2 of setting a green rubber sheet made of a rubber material for use in a blanket, on the reinforcement member 3 set onto the mold, a vulcanizing step P3 of forming teeth T . . . for use in a timing belt on an inner surface thereof by vulcanizing an intermediate produced article obtained on the rubber sheet setting step P2, and obtaining an endless timing belt having the reinforcement member 3 at an inside thereof, and a blanket surface working step P4 of working an outer surface of the timing belt on a blanket surface, after vulcanizing. Thereby, both of expansion and contraction of a blanket surface and a slip thereof to the pulleys are prevented effectively.

摘要： There are provided an operating mechanism 5 having an operating portion, for example, freely rotatable roller 4, which is displaced to a setting position Ps of pressure-contacting to the plate belt 2 by a spring member 3 and a releasing position Pr spaced apart from the plate belt 2, a fore clamping mechanism 8 supported in a seasaw manner on widthwise supporting shafts 6 . . . disposed on the plate belt 2, and having clamping portions 7c . . . for clamping a fore portion of the plate S at one end thereof, operated portions 7m . . . pressed by the freely ratable roller 4 at the setting position Ps, at the other end thereof, and fore clamps 7 . . . pressed in a clamping direction by spring members 9 . . . , and a rear clamping mechanism 12 supported in a seasaw manner on a widthwise supporting shaft disposed on the plate belt 2 at a rearward of the fore clamping mechanism 8, and having a clamping portion 11c for clamping a rear portion of the plate S at one end thereof, operated portions 11m . . . pressed by the freely rotatable roller 4 located at the setting position Ps, at the other end thereof, and a rear clamp 11 pressed in a clamping direction by spring members 13 . . . . Thereby, a miniaturizing of the whole printing machine can be caused, and further a reliability and a maintainability thereof can be improved.

摘要： A random access mailbox has a stack of horizontally extended trays for receiving sheets of paper supplied from a printer. A modular construction provides a sheet transport system including gates to deflect sheets into a selected tray from sheet feeding rollers incorporated in the modules for carrying sheets through a sheet path defined between the rollers and pressure applying rollers to the respective gates which can be actuated randomly to deflect a sheet from the rollers into a selected tray between cooperative modules. A sheet detector is provided at each gate along the feed path to detect the presence of a sheet at any location along the feed path. The gates or deflectors nest or overlap vertically to reduce overall height of the apparatus and provide continuity to the sheet guide surfaces.

摘要： A sorter of the moving bin type has a set of horizontally extended trays moved vertically between positions above and below a sheet entry location by cams which provide an enlarged entry space. A stapler is moved between a non-stapling position and a stapling position. The cams also enlarge the space between trays at the stapling position to permit a tray to be received in the throat of the stapler between stapler anvil and body. A sheet aligning jogger has opposed jogging bars extending vertically at opposite sides of the trays and simultaneously moveable towards and away from one another to engage opposite sides of the sheets in the trays to align the side edges of the sets of sheets in a neat stack. The jogging bars are also rotated in opposite directions to apply a force to the sheets urging the trailing edge of the sheets opposite to the direction of feed into the trays against an alignment surface on the tray normal to the side edges for aligning the trailing edges of the sheets in the set.

摘要： A compact, low-height offset press of simple construction is easy to use, needs no after-use maintenance such as cleaning the ink roller and is designed for fully automatic operation. Plate support 1 and blanket support 10 consist of endless belts. Etching unit 60, dampening unit 70 and inking unit 80 are placed along the periphery of the plate support. An unetched plate is supplied from the plate supply unit and etched automatically for printing. When the press is not in Use, anti-drying tank 95 moves up, enclosing the roller(s) in liquid, to prevent any ink on the roller surfaces from drying.

摘要： A moving bin sheet sorter has rotatable cams which engage portions of the sorter trays to move the trays at the ends adjacent to a sheet entry location between positions at which those tray ends are closely spaced above and below the sheet entry location and further spaced apart at the sheet entry location for receiving sheets supplied from a copier or printer. The cams are driven by an electric motor which is controlled to operate at a low speed as the trays are initially engaged and disengaged from the cam and a high speed during the major movement of the trays, thereby reducing noise resulting from high speed impact and shock loading of the cams and cooperative portions of the trays, as well as reducing noise resulting from high speed impact of said cooperative portions of the trays in guides for the trays.
