Abstract: A belt press uses differential thermal expansion between parts of a platen assembly to generate pressure. The belt press typically includes substantially aluminum platen assemblies that are connected such that movement of the second press surface away from said first press surface is limited. A plurality of expansion limiting rods are aligned generally parallel to the top platen's longitudinal axis and attached thereto. The expansion limiting rods preferably are attached via adjustable couplings to sturdy anchor bars laterally disposed across the platen and rest against two or more bridging rods midway along the length of the platens. The expansion limiting rods have a coefficient of thermal expansion that is smaller than the coefficient of thermal expansion for the platens.
Abstract: Colored or metallic foil is applied to toner printed onto a substrate, such as paper, in a high speed, versatile manner, using a rotating impression cylinder, and a rotating transfer cylinder having circumferentially spaced heated raised portions. The toner, which preferably includes a thermoplastic component, is applied to the paper with any suitable printer, such as a computer controlled MIDAX (ion deposition) print engine. The toner may be heated by an infra red heater just before the paper is fed to the nip between the impression and transfer cylinders. A foil strip having an adhesive layer facing outwardly, a foil layer, and a release coating on a backing, is also fed to the nip, and the backing taken up downstream of the nip. Heat and pressure applied at the nip transfer the adhesive and foil from the foil strip to the tacky toner, producing the desired foil printed paper, which then may be further processed.
Abstract: An identification booklet including a backing and a printed cover film having identification indicia printed thereon is automatically printed and assembled by an apparatus including means for holding the booklet in an open position with the backing exposed, printing means for printing indicia onto an inner surface of the cover film, transport means including an insertion blade rotatably mounted thereon, the insertion blade including a damp for holding the cover film in place thereon, die-cut means for cutting the cover film to a predetermined size while the cover film is held in place on the insertion blade by the clamp, to form the identification card and fusing means for fusing the identification card and the backing together.

Abstract: A method and an apparatus for manufacturing thermoset webs of thermoplastic polymer material which is comminuted into particles, such as flakes, granulated material or the like or is ground into powder. The thermoplastic polymer material particles are distributed uniformly on the lower conveyor belt; the distance between the lower and upper conveyor belt is maintained equal to the thickness of the web to be manufactured; the initial layer poured onto the surface area of the lower conveyor belt is applied with such a thickness of the layer that the thermoplastic polymer material particles are subjected during the entire transport between the upper and lower conveyor belts in the heating and cooling sections only to a minimum pressure of at most 0.
Abstract: A method of veneering across a elongate corner on an elongate core involving providing a sheet of veneer sized to cover a desired portion of the core including an expanse on each side of the corner with the veneer having a core side for placement against the core and an exposed side opposite the core side. An elongate groove is formed in the core side of the veneer with the groove having a generally triangular cross-section with an open side substantially coplanar with the core side of the veneer and two interior sides extending into the veneer to a point near but not reaching the exposed side of the veneer where the angle between the interior sides being configured to match the angle of the corner. Lastly the veneer is applied to the core with the groove aligned over the corner and veneer on either side of the groove folded down against the core to thereby bring the two interior sides of the groove together.
Abstract: An apparatus for applying an image to a spherical surface utilizing a heat transfer device having a heating die with a convex surface. The concave surface allows for the transfer of an image onto an object having a spherical surface, such as a baseball or softball, without deforming said object.

Abstract: There is described a method of manufacturing a flat friction ring which consists of a supporting ring (1) and a friction lining (2) provided on at least one side of the supporting ring and at least approximately forming radial oil grooves (3), which friction lining is first cut out of a friction lining web including slits (5) extending from at least one circumferential side for forming the future oil grooves (3), and is then glued onto the supporting ring (1). This method is characterized in that the friction lining (2) is cut out of the friction lining web in the form of a strip (7) and in the area of the connecting webs (6) between the friction lining sectors (4) separated from each other by the slits (5) is bent in a polygon-like manner to form a ring and is glued onto the supporting ring (1).
Abstract: An apparatus for manufacturing a liquid crystal panel in which two substrates are faced to each other with spacers interposed therebetween, applied with heat and pressure in an overlapped condition, and adhesive arranged between two substrates is cured for fixing, characterized in that at least one of a pair of pressurizing plates for applying pressure to the two substrates is a graphite plate and in that upper and lower pressurizing plates are made to be of different rigidity. The graphite plate of low rigidity is made to stick to the substrate, and shifts between substrates can be prevented while securing uniformity in gaps between substrates.
Abstract: A device and method that employs prints produced by video color system thermal printers as transfers for creating personalized ceramic mugs, tiles or the like articles. The method comprises creating a mirror image print by means of a color video system with printer, applying that print to the surface of the mug or the like which has been treated with a sublimable dye absorbing compound, and applying heat (200 to 400° F.) and pressure exerted by a force of 200 to 400 pounds for period of time of about three to six minutes, to sublimate the limited dye in the print whereby it is absorbed by the coated surface of the mug or the like. The device for applying the heat and pressure is a heated press that has removable heated slidable platens which conform to the shape of the article to which the print is being transferred.
