    摘要: A vacuum assisted sheet transfer assembly has an array of support bars which support the unprinted side of a freshly printed sheet along a sheet transfer path. The support bars overlie the airflow inlet of a manifold housing, with the longitudinal axis of each support bar extending across the sheet transfer path. The support bars provide smooth surfaces for engaging and supporting the unprinted side of the sheet material as it is pulled along the transfer path while simultaneously limiting the flow of inlet air through elongated inlet apertures. As air is drawn through the inlet apertures, the unprinted side of the sheet is sucked into engagement with the support bars as it moves along the sheet transfer path. The sheet transfer assembly eliminates the need for conventional skeleton wheels and the like. Marking, smearing and smudging are prevented since the printed side of the sheet is not handled or contacted in any way as the sheet is conveyed along the sheet transfer path.

    摘要: A vacuum transfer apparatus for use in a sheet fed rotary printing press for supporting the unprinted side of a freshly printed sheet as it is moved from the press impression cylinder along a transfer path to a further processing station of the press, the apparatus including a vacuum chamber supporting a plurality of rotatable elongated rollers arrayed in spaced side-by-side parallel relationship laterally across the transfer path, and a vacuum pump connected to the chamber for producing a pressure differential across the freshly printed sheet to draw the unprinted side of the sheet into engagement with the support rollers by drawing air into the vacuum chamber through the spaces between the rollers as the sheet is pulled along the transfer path so that the printed side of the sheet can not be marked or marred.

    摘要: A sheet transfer assembly for use above an ultraviolet curing unit in a flexographic printing press used for printing corrugated sheets includes a vacuum plate with heat sinks. The vacuum plate includes openings for rollers that extend through the vacuum plate to drive printed sheets across the bottom of the transfer assembly. Heat sinks are formed on the top surface of the vacuum plate between rollers to remove heat from the vacuum plate. Heat from the UV curing unit is effectively dissipated from the vacuum plate into the air used to hold printed substrates against the rollers in the transfer assembly.

    摘要: A multipart printing press cylinder. A pair of hubs have an inner bore for mounting on a press shaft. Each hub is made in two parts which may be positioned about the press shaft and attached to each other by, e.g. screws. Each hub has a profile section. A pair of partial shells each include a pair of cylinder frames having a profile matching a hub profile. Manually releasable latches are provided for holding each partial shell on the hubs when the partial shell profiles are mated with the hub profiles. The outer perimeter of each cylinder frame has a radius and contour defining the outer size and shape of a printing press cylinder. A surface material, e.g. sheet aluminum, is formed to fit the frame perimeters and are preferably attached under tension to the frames.

    摘要: A zoned UV curing system for drying UV inks and coatings in printing presses. A plurality of linear UV lamps are spaced apart laterally across the travel path of substrates in a press. The axis of each lamp is aligned generally with the travel path, but may be slanted slightly so that every point on the travel path passes directly under at least one lamp. Power supply and control means allow selection of which lamps are powered, so that unneeded lamps may be turned off to save power. The power level of each lamp is variable. One transverse UV lamp may be placed upstream to initiate curing before substrates pass the zoned system. An IR heater may be placed upstream to preheat UV ink and coatings to enhance curing and to smooth coatings.
