Abstract:
Una imagen transferida permanentemente a un sustrato teniendo un componente de algodon, u otro componente el cual es absorbente o poroso desde un medio impreso con la imagen mediante una impresora impulsada por computadora. Un material de preparacion de superficie de polímero y una tinta son transferidos por la impresora al medio desde una cinta o composicion de tinta conteniendo la tinta y el material de preparacion de superficie, sin activar el material de preparacion de superficie. La imagen es transferida desde el medio al sustrato mediante el aplicar suficiente calor y presion al medio para transferir la tinta y el material de preparacion de superficie, con el material de preparacion de superficie uniendo la tinta al sustrato.
Abstract:
A forming press of the pressure cell type comprising a press stand, a pressure cell arranged in the press stand with an elastic diaphragm (23) and a tray-shaped tool-carrying member, which is insertable into the press and in which a forming tool and a work piece are located. According to the invention the pressure cell is formed from a substantially plane diaphragm (22), a substantially plane surface of the press ptate, and a sealing ring (23) disposed around the periphery of the diaphragm to bridge a gap between the diaphragm and the press plate. The sealing ring (23) is U-shaped with its flanges (23a, 23b) directed inward towards the centre of the pressure cell. Inside the sealing ring (23) spring elements (30', 32) are arranged to urge the flanges of the sealing ring outwardly to provide initial contact pressure with the diaphragm and the press plate. respectively.
Abstract:
(57) In a method for manufacturing a laminated plate material by compression forming, material (102) for laminatio is sandwiched between two pressure plates (100), and a layer of fluid pressure medium is sandwiched between said material (102) for lamination and one of said pressure plates (100) and is pressurized so as to pressurize said material (102) for lamination. Thereby, the pressure is well distributed over the superficies of the material (102) for lamination, thus ensuring a good and uniform product. A device is also disclosed for performing the method.
Abstract:
A device for holding, in a braking manner, a preferably sheet-formed blank (31) when forming the blank in a fluid cell press. During the forming, a hydraulic forming pressure is applied, via an elastic diaphragm (4), to one side of the blank. The device comprises first means (18) for generating a hydraulic blank holder pressure and second means (15, 16, 17a) for supplying this pressure to a movable member (14) and maintaining this pressure. The movable member is adapted, as long as the blank holder pressure is maintained, to hold part of the blank in a braking manner against a support (13). To improve the forming result, the device comprises means (20) which, under the direct influence of the forming pressure, reduce the blank holder pressure when the forming pressure attains a predetermined value.
Abstract:
This invention relates to a pressure molding apparatus characterized in that a molding precursor, for example, green sheets are packed in a recess (3b) in a pressure container body (3), the recess being then closed with a covering member (6), the green sheets being heated with a heating means as they are pressed by a pressure medium P1, these green sheets being molded into a unitary laminate by being thus heated and pressed, a pressing force used during the green sheet pressing operation being preferably varied.
Abstract:
This invention relates to an apparatus and method for uniformly transmitting pressure to laminate a conductor or printed circuit to an at least two-dimensional substrate surface so that the bonding of one to the other is uniform across the surface including the periphery of the surface. The invention includes multiple platens disposed opposite each other. One platen contains a cavity for insertion of a substantial thickness of the substrate while the other platen has attached to it a cylinder having portions of its volume divided by multiple diaphragms. One of the diaphragms is a mold shaped to be a mirror image of the surface of the substrate, and which is confined in the distal end of the cylinder. An alternative embodiment is directed to the use of a bellows attached to the noted platen in place of the cylinder. The bellows has at its distal end the mentioned mold. This technique permits not only a uniform lamination technique, but also provides a technique for eliminating the hazard of using a bladder with hot pressurized fluid which can burst or jet fluid at personnel.
Abstract:
To coat panel-shaped workpieces with a film, a coating press is provided. Positioning of the workpieces on the support table, independently of a pre-calculated layout pattern and the workpieces delivered thereto, can be simplified and quickened to a large extent in that the support table (1) has a table top with grid-like openings (3) into which carriers (7, 27) for the workpieces (2) are displaceably inserted. At least the length of each carrier (7, 27) can be easily changed to be reversible in such a manner that inside the coating press the extended carriers (27) positioned on the contact surface project up from the table top and the workpieces (2) mounted on said carriers are raised in relation to the surface of the table top and the shortened carriers (7) which are not or only partially covered.
Abstract:
A membrane press comprises a first part including a pressure chamber closed by a flexible membrane, and a second part comprising a bed for receiving a workpiece, the first and second parts being relatively movable between an operative position, wherein the membrane is in contact with the bed and/or with a workpiece thereon, and an inoperative position, wherein the membrane is spaced from the bed, releasable locking means being provided to lock the first and second parts together in the operative position while pressure is applied to the membrane.
Abstract:
An image is permanently transferred to a substrate having a cotton component, or other component which is absorbent or porous, from a medium printed with the image by a computer driven printer. A polymer surface preparation material and an ink are transferred by the printer to the medium from a ribbon or ink composition containing the ink and the surface preparation material, without activating the surface preparation material. The image is transferred from the medium to the substrate by applying sufficient heat and pressure to the medium to transfer the ink and the surface preparation material, with the surface preparation material bonding the ink to the substrate.
Abstract:
An image is printed on a medium by means of a computer-driven printer (6) using an ink composition comprising heat-activated dye solids, without activating the dye solids during the process of printing onto the medium. The image is transferred from the medium to the object (8) on which the image is to permanently appear by applying heat and pressure to the medium to activate the dye and transfer the image to the object (8). The liquid form of the ink composition uses a liquid carrier and an emulsifying enforcing agent which has an affinity for the dye. The emulsifying enforcing agent shields the heat-activated dye both prior to, and during, the printing process.
