摘要:
A heat transfer device for sheet assembly for the heat transfer of an image on a transfer sheet to a receptor sheet for printing by inserting a sheet assembly comprising the transfer sheet on which an image has been formed and a receptor sheet for printing superimposed on an auxiliary plate into an inlet opening portion formed on a casing along an inlet stand, and passing between a pair of heat pressure rolls arranged inside the casing, includes: an exhaust fan for taking the outside air from the inlet opening portion toward the pair of the heat pressure rollers for cooling the pair of the heat pressure rollers; and aperture maintaining means for maintaining air passage for allowing the intake of the outside air between the upper edge portion of the inlet opening portion and the upper surface of the sheet assembly at the time of inserting the sheet assembly into the inlet opening portion. Accordingly, the pair of the heat pressure rollers can be securely cooled by the outside air via the air passage.

A laminator carrier, which holds superposed sheet members, is subjected to heat and pressure while being transported. The laminator carrier includes a carrier base on which the superposed sheet members are placed, a cover sheet which is disposed on the carrier base so as to cover the sheet members placed on the carrier base, a holding mechanism for holding the cover sheet such that the cover sheet is movable with respect to the carrier base in a transport direction of the laminator carrier. Accordingly, movement of the cover sheet during application of heat and pressure is absorbed by the holding member.

A device for unloading metallized belts comprises a pair of parallel arms rotatably mounted respectively between each of two lateral side walls of the last station of the machine. The arms are connected to one another by crossbeams, which may accept support levers for small-diameter bobbins. Each arm has a base plate for supporting the ends of the axles for the large-diameter bobbins. The device includes an arrangement for rotating the sub-frame formed by the arms from the operating position to an extended position, which has a portion of the arms extending out of the downstream end of the machine to enable exchanging bobbins.

A rotary embossing machine includes an embossing mechanism in which an embossing gap is formed between an embossing cylinder and a counter pressure cylinder. For conveying an embossing film web through the embossing gap, the rotary embossing machine includes a conveying mechanism for producing a movement of the web at the same speed as a material layer to be embossed, during an embossing interval. The film conveying mechanism includes a pulling device downstream of the embossing gap which is provided with a slip drive for the embossing film web and a controllable film supply device upstream of the embossing gap which cooperates with the pulling device. This arrangement avoids the risk of the embossing films or foils tearing and improves the embossing quality.

A method and tool applicator for applying a heat transfer flock material portably to cloth surface such as automobile seats to allow the use of logos, letters, numbers, and any graphic design to be portably placed without having to remove the material from its present location without having to apply great pressure. The invention includes applying heat through a thermal barrier that protects the seat and the device from excessive heat with a hand-held tool for a predetermined amount of time, which allows the adhesive on the flock material to bond with the seat fabric.

An image-transfer apparatus for producing an aesthetically fine transfer image includes a platen having a cut-off portion on the surface formed for attaching an image-forming material and a transfer cylinder having a cut-off portion on the surface formed for attaching an image receptor. The apparatus allows the introduction of the image-forming material and the image receptor into a nip formed by the platen and the transfer cylinder by the rotation of the platen and the transfer cylinder to transfer an image formed in a photosensitive layer of the image-forming material to the image receptor heated to a transfer temperature. The transfer cylinder, other than the cut-off portion, has a cylindricity of 100 .mu.m or less, a circumferential deviation, measured in the radial direction of the transfer cylinder, of 60 .mu.m or less and a straightness, measured on a cylinder surface, of 60 .mu.m or less when heated to and kept at a transfer temperature.

The invention refers to an apparatus for testing the color separations of a multicolor print, comprising a pair of press rollers being mounted in a frame and constituted by rollers which can be lifted off each other, through the roller gap of which an image-bearing element consisting of a support foil with an exposed, photosensitive layer, with a color foil, consisting of a color-bearing foil with a color layer, being placed on this element, is fed such that portions of the color layer adhere to the tacky areas of the image-bearing element. For the solution of this problem to provide an apparatus of the kind by which the testing of the color separations of a multicolor print can be carried out in a simple and rapid manner, a movable frame is provided in which a plurality of pairs of roll bearings for rolls to be unwound and wound up are mounted. A roll bearing for each pair of rolls allows a roll of a color foil web to be loaded, and the color foil web can be wound up on a roll carried in the other roll bearing. The web section of the color foil web between the rolls of a pair of roll bearings runs in between the press rollers of the pair of press rollers.

A plastic article such as key tops of a key board needs wear resistant printing. This is attained in a styrene-based resin body suitable for such an article including key tops, by a process for permeation printing, comprising the steps of printing an article with an ink comprising a medium having a solubility parameter of 8.5 to 11.5 (cal/cc).sup.1/2 and then covering the printed surface of the article to permeate the ink into the article. Further, a system suitable for permeation printing a plastic article is provided which comprises a transfer-type printing device and a body heating and covering device, the body heating and covering device comprising a covering body which is heated and covers the printed surface of the plastic article to cause ink to permeate into the plastic article.
摘要:
An apparatus for dry printing onto a workpiece (12) using a hot embossing film (10) and an emobssing die (1) is shown, whereby the hot embossing film (10) adheres onto the workpiece (12) corresponding to the embossing die (1) and after a cooling period the film, except for the impression itself, is released from the workpiece. The walls of the die body (2) are so thin that, as it is placed onto the workpiece (12) to be printed onto, it forms locally and elastically onto the workpiece surface (11). The side of the die body (2) facing away from the die face (3) displays a positive force transfer relief (7), which corresponds to or which is similar to the die face (3). On the side of the die body (2) facing away from the die face (3) there is an elastic pressure pad (8) for the die body (2) to form locally and elastically.
