  • Patent number: 6205918
    Abstract: A stencil printer includes a plurality of ink drums spaced from each other in the direction of paper conveyance and each having a respective master wrapped therearound. An upstream ink drum and pressing means movable into and out of contact with the upstream ink drum define an upstream print position. A downstream ink drum and pressing means movable into and out of contact with the downstream ink drum define a downstream print position. An intermediate conveyor is located between the upstream print position and the downstream print position for conveying a paper carrying an image printed at the upstream print position toward the downstream print position. A distance which the paper moves from the upstream print position to the downstream print position is longer than a distance between the upstream print position and the downstream print position. Defective printing is reduced even when the peripheral speed of the upstream ink drum and that of the downstream ink drum are different from each other.

  • Patent number: 6152031
    Abstract: A screen printing system has multiple screen cassettes stored in a magazine and a first screen cassette is transferred from the magazine into a printing station. A motorized pallet conveyor conveys a plurality of substrates, each of which is loaded one of a series of pallets of the conveyor, into and from the printing station and about an endless path. After printing the first image or color, the first screen cassette is returned to the magazine and a second preregistered screen cassette is brought to the printing station with a second image or color being printed on each substrate as the pallets carrying the substrates are conveyed into and from the printing station. Preferably, the substrates and pallets are maintained in a horizontal position while they travel laterally, downwardly and upwardly when moving along the endless path.

  • Patent number: 5908000
    Abstract: A multi-colored silk screen printing machine has an improved electric resistance heating station to cure silk screen printed ink on a substrate such as a textile. A control system has a proximity switch that detects the presence of a pallet within the heat curing station and starts supplying electrical power to a bank of electric resistance heaters automatically only when a pallet is present. An infrared temperature sensor is used to measure the ink temperature when the bank of electric resistance heaters is heating the printed ink on the textile. The infrared sensor provides a signal to a control system that interrupts power to the bank of electric resistance heaters when the signal exceeds a preselected maximum ink temperature value. A timer can also be used to override the infrared temperature sensor. A sheltered passageway and a low level air flow therethrough protect the face or lens of the infrared sensor from gases, smoke or other types of contamination.

Thus, the squeegee can be made to always print across the square-shaped mesh of the woven screen rather than across diamond-shaped mesh whereby to eliminate or at least minimize or localize moire. The silk-screen frame and squeegee can be rotated together to a predetermined angle or degree, in advance of the printing of a particular color in the silk-screen printing of halftones.

  • Patent number: 5613436
    Abstract: An adjustable pin registration plate assembly for use in a single or multiple station silk screen printing press apparatus which includes an apparel support platen mounted on an elongated support arm and at least one pivoting silk screen frame support assembly movably suporting a silk screen frame above the apparel support platen. The registration plate assembly comprises a flat plate portion having a plurality of pairs of spaced vertical bores therethrough and a pair of pins each extending upwardly from the plate portion through one of the bores and adjustably secured in the bore. The pair of pins fit into correspondingly spaced holes in the rear side of the silk screen frame to provide final alignment of the frame on the apparel support platen as the frame is lowered into position. The pins are adjustable in height above the plate portion to preclude binding during frame placement and removal from the apparel support platen.

  • Patent number: 5590596
    Abstract: A printer system prints a given pattern of viscous conductive ink on a base board with the aid of a screen plate. The system has a printer device which moves horizontally when carrying out printing. The printer device includes two spaced side walls. Two stationary parallel rails extend horizontally to respectively support, through the screen plate, the side walls of the printer device during the horizontal movement of the printer device. The screen plate is tightly placed on the rails. A supporting device is employed for stationarily supporting the base board under the screen plate.

    Abstract: A screen printing apparatus transfers an image onto a substrate. A feed mechanism is provided for moving the substrate along a fixed linear path. Vacuum is provided through the feed mechanism for holding the substrate in at least one position along the fixed linear path. A printing head transfers the image onto the substrate while the substrate is held in a first position by the vacuum. A curing station is provided for fixing the image transferred to the substrate while it is passing through the curing station, or while it is being held in a second position by the vacuum applied through the feed mechanism.

  • Patent number: 5483881
    Abstract: A screen printing apparatus comprising a plurality of print stations arranged in a circle and an equal plurality of platens carrying objects to be printed by the print stations. Objects to be printed are placed on platens at a loading/unloading one of the stations and the platens are indexed around the circle of print stations for printing. A control unit controls the printing at the print stations and selectively inhibits printing at individual ones of the print stations. During start up, the control unit activates print stations, one at a time, in synchronism with the indexing of the platens. A skip mode is available in which printing at a given platen is inhibited by the control unit at each print station, when the given platen is at that print station. The control unit also successively inhibits print stations, one at a time, in synchronism with platen indexing to provide a controlled stop of the apparatus.
