Patent number: 5123345Abstract: The squeegee arm and screen frame portions of a tilt screen type screen printing machine are pivotally connected to specially designed rocker housings slidably movable along horizontal support rods. The rocker housings have portions which are not rotated by pivoting of the squeegee arm and screen frame, thus permitting such rocker housing portions to be horizontally driven along the support rods by rodless air cylinders mounted on the machine. Additionally, the nonrotatable portion of the screen frame rocker housing carries a horizontally disposed gear rack which can be operatively mated with a pinion drive gear portion of a rotatable fixture supporting a round item to be printed so that horizontal translation of the rack rotationally drives the fixture during the screen printing process. Because of the rocker housing design, upward tilting and horizontal movement of the screen frame does not disrupt the rack and pinion registry.Type: GrantFiled: July 25, 1990Date of Patent: June 23, 1992Inventor: Gary E. Wood

Patent number: 5088401Abstract: In the marking method and apparatus, a printing plate which is mounted to a plate holder is moved horizontally and vertically and set above a workpiece. The printing plate is then lowered quickly until it comes into contact with the workpiece upon which printing is performed and then, based upon a signal from a detector which detects such a contact of the printing plate to the workpiece, the printing plate is further lowered slowly a predetermined fixed distance. Thus, even if the thickness of the workpiece is different from workpiece to workpiece, the pressing-in amount of the printing plate into the workpiece can be constant for different workpieces.Type: GrantFiled: November 30, 1990Date of Patent: February 18, 1992Assignee: Kabushiki Kaisha ShinkawaInventors: Noboru Fujino, Tohru Takamura

Patent number: 5054390Abstract: An ink design is silk screened onto an intermediate surface and is then transferred to an article by a deformable pad. In order to provide a large difference in the ink affinities of the intermediate surface and pad, these are made of silicone rubbers in which different catalysts are used in the curing of the rubbers. Dibutyltindilaurate as catalyst provides an intermediate surface of low ink affinity which can enable 100% transfer of ink from the intermediate surface to the pad when a stannous octoate catalyzed, condensation cured rubber, or a suitable addition cured rubber, is used for the pad. The screen is heated to a greater temperature than that of the intermediate surface.Type: GrantFiled: January 28, 1988Date of Patent: October 8, 1991Assignee: British Ceramic Research Association Ltd.Inventors: John F.

Patent number: 4615266Abstract: A pad transfer printing machine is disclosed in which the engraved printing plate is suspended face-down at an elevated position above the surface to be printed, and is horizontally movable between a retracted position and a pad contacting position. The plate is inked and scraped as it moves horizontally and, at the pad contacting position, presents an inked image to a deformable transfer pad. A movable printing member drives the transfer pad in alternating upward and downward strokes and inverts the pad during each upward and downward stroke, so that the transfer pad is alternately brought into contact with the printing plate at the top of its stroke and with the surface to be printed at the bottom of its stroke. The elevated position of the printing plate renders it easily accessable for removal and replacement. Excess ink is automatically removed from the printing plate by the scraping device as the plate is removed, and the excess ink is returned to the ink supply.Type: GrantFiled: October 16, 1984Date of Patent: October 7, 1986Assignee: Markem CorporationInventors: William M.

Patent number: 4593616Abstract: A dabber printing machine for printing of workpieces with printing ink wherein a dabber-holder is fastened from below to a first and second vertical carriage (6, 6'). The dabber-holders run parallel to one another. In each case, in one extreme position of the horizontal carriage (7), with which both vertical carriages (6, 6') are connected, the vertical carriages (6, 6') are pressed downward by two levers (14) of a pair of gear units (12). In the other extreme position, such are pressed downward by the levers (14) of the other pair of gear units (12). Thus, the dabber-holders with the dabbers jointly and simultaneously make vertical and horizontal movements in the form of an inverted U. A step of operation of the transfer element from printing station to printing station optically occurs upon every or every other horizontal movement. Thus, indexing of the workpieces to be printed is simplified and the efficiency of the printing machine is doubled.Type: GrantFiled: October 4, 1984Date of Patent: June 10, 1986Assignee: MADAG Maschinen-und Apparatebau Dietikon AGInventor: Silvano de Lorenzi

Patent number: 4019436Abstract: A technique for producing a pre-distorted design format on a printing plate for use in a print transfer system in which an inked design engraved on the plate is picked up by a soft transfer pad and applied to the irregular surface of an article to be decorated, the pad being forced against the surface and conforming thereto to impress the inked design thereon. In this technique, a physical master is created which is an exact replica of the article to be imprinted, the irregular surface of the master being engraved or otherwise prepared to accept ink to define the design which is to appear on the article. The design on the master is inked, and this inked design is picked up by the transfer pad and applied to the regular surface of a proof sheet, whereby the distortion in the design impressed on the proof sheet reflects the distortion introduced by transferring from the irregular to the regular surface.Type: GrantFiled: June 16, 1976Date of Patent: April 26, 1977Inventors: Martin Handweiler, George Castanis
