Abstract: A layered-up veneer board is formed by layering veneers up to a predetermined height such that the fiber directions of the respective veneers are alternately perpendicular to one another, and the layered-up veneer board is compressed by a compression device, to remove moisture contained in the veneers. Wood is a material in which the tensile strength in the fiber direction of the wood is higher than the tensile strength in the direction perpendicular to the fiber direction. With this layering scheme, even when stress is applied to the veneers and causes elongational deformation of these veneers as a result of compressing the layered-up veneer boards in the layering direction, elongational deformation of the veneers in the directions perpendicular to the fiber directions thereof can be reduced.

Abstract: A three part laminated material for use in making blister packages and a method of making such a material. The material is comprised of a central core layer of poly chloro-tri-fluoro ethylene to each side of which a separate polymer film is adhesively attached. The method of making the material involves use of a corona treater, a vertical forced air convection dryer, a horizontal convection dryer, a motor driven rewind, a chilled cylinder, a primary unwind and at least one laminating unwind. In the preferred embodiment, each of the polymer films is polyvinyl chloride, although a variety of different films may be used. The disclosed material provides a high moisture barrier, a stable inter-laminar structure and outer surfaces which lend themselves well to bonding with other materials.

Abstract: The disclosure relates to a method of producing a well-integrated laminate material, for example a packaging laminate, in which method a first web (10a) of plastic, and a second web (10b) of plastic are brought together and permanently united to one another by the simultaneous application of heat and pressure, for the formation of the laminate material (10). In order to improve the adhesion between the webs (10a and 10b), these are subjected to a surface-activating treatment of non-chemical nature, preferably a corona treatment, prior to the uniting of the webs, whereby good adhesion and bonding between the webs is achieved without the employment of interjacent chemical adhesives.

Abstract: The present invention provides a film roll comprising an electrified portion at at least part in the transverse direction of a film that is wound into a roll, in which the difference between the maximum width and the minimum width of the electrified portion is 10 mm or less. In this manner, side slipping can be reliably prevented while securing escapeways for air at the edges, and a film roll having no side slips, wrinkles, deformation, decentering, or the like can be manufactured. The film roll of the present invention can be manufactured by intermittently electrifying the film at a predetermined cycle, the ratio of the time duration of the electrification in the cycle being 10 to 80%. The film roll of the present invention has a high adhesive force and does not suffer from slipping during evacuation in a vacuum evaporator. Thus, the film roll is suitable as a master roll for metallization and can be suitably applied to various uses such as magnetic tapes, packaging materials, capacitors, and the like.

Abstract: In a film lamination apparatus and method, there is no one-side contact of a pressing roller that presses a film to be laminated. The film is laminated using a rotatable pressing roller having a heater incorporated therein. The pressing roller is pressed onto the film placed on a semiconductor substrate while generating heat by the heater inside the pressing roller. The pressing roller is rolled on the film so as to laminate the film on the semiconductor substrate by partially heating the film by the pressing roller while moving the pressing roller.

Abstract: The present invention relates to a method for manufacturing a pressure container comprising an inner liner layer of polymer material, such as polyolephines or a similar material, and an outer, fiber-reinforced and pressure supporting layer, characterized by treatment of the outer side of the inner liner layer so as to increase the wetting and adhesive properties of the polymer material, employing an adhesive at the outer side of the inner liner layer and/or in direct contact between the outer side of the inner liner layer and the inner side of the outer fiber-reinforced, pressure supporting layer, and winding of the outer, fiber-reinforced and pressure supporting layer onto the inner liner layer. In a preferred embodiment the treatment of the outer side of the inner liner layer comprises flaming, but also corona-discharging, possibly in combination with ozone treatment, or a corresponding method for improving the wetting and adhesive properties of the polymer material can also be employed.

Abstract: A workpiece is passed at high speed through an electrostatic flocking chamber provided with an inlet opening and an outlet opening, a distance between which openings is increased to realize optimum flocking conditions for the workpiece being electrostatically flocked. In order to conduct an electrostatic flocking operation of the workpiece by having the workpiece traveled at high speed between the inlet opening and the outlet opening, a pair of electrodes are disposed parallel to a passage of the electrostatic flocking chamber, which passage is increased in length to permit the workpiece to pass through the passage at high speed. A high voltage is applied to a first one of the electrodes, while a low voltage lower than the high voltage is applied to a second one of the electrodes, wherein the first and the second electrode are disposed in the inlet opening's side and the outlet opening's side, respectively.

The second plastic part is introduced into the first plastic part, to which it is connected by means of an interference fit connection, whereby at least one contact zone between the second plastic part and the first plastic part is formed as a result of this interference fit. A laser beam is directed to impinge on the second plastic part, through the first plastic part, along the at least one contact zone to form a weld.

Abstract: A method for grounding reinforcement (12) and composites (17) on a calender line reduces static build up on the composite (17), and makes it possible to subject a wire reinforced composite to electron beam processing (EBP). The method employs a slip ring (36) attached to rolls which contact composite (17) on the calender (11), and reinforcement (12) before it reaches the calender (11), wherein the slip ring (36) rotates with the rolls while the rolls are working polymer into the reinforcement, and a terminal (34) connected to the slip ring (36) remains stationary, and the terminal (34) is attached to ground (27). The method effectively grounds the composite as well as the reinforcement to prevent electrical discharge during EBP.
