Abstract: A method for making a composite lined tube is disclosed, wherein the tube has end couplings on it. The method includes pressing a resin impregnated fiber preform progressively along an inner wall of the tube. In one embodiment, the method includes inserting an inflatable bladder into the tube. The bladder is adapted to inflate along a length thereof on application of increasing pressure to the interior of the bladder. The bladder has disposed on its exterior surface the fiber preform impregnated with resin which is adapted to fit within the tube. One end of the preform is secured to one end of the tube. The bladder is then inflated along its length by applying increasing pressure to the bladder. The preform is clamped to a shoulder of one of the couplings at another end of the tube, and the end of the preform is trimmed to conform to the shoulder. Pressure is maintained in the bladder while curing the resin. In one particular embodiment, the bladder is inflated from its center outwardly to its ends.

Abstract: A highly stretched film has permanently heat-sealed edges that are nearly invisible. A folding apparatus folds the edge portions of a film to form folded edges. The folded film then is passed through a bridle mechanism having two heated rolls. A series of nips apply pressure to the folded film as it is heated by the heated rolls. The nip pressure, combined with the heat imparted by the heated rolls, causes thermal welding of the folded edges resulting in permanent heat-sealed edges. Because the film edges are folded prior to the hot-stretching, the hot stretch process performs dual functions of stretching the film and heat sealing the folded edges. The resulting stretched film has permanently heat-sealed edges that do no separate, and which prevent tearing of the film edges during subsequent processing and use.

Abstract: A method produces adhesive closing parts having adhesive closing elements made of plastic materials. The elements interact with corresponding adhesive closing elements of a second adhesive closing part to form an adhesive closure. The adhesive closing part having the adhesive closing elements is applied, at least in part, with a coating. The thickness of the coating is chosen such that it ensures subsequent formation of an adhesive closure. Adhesive closures with enhanced application possibilities can thus be produced.

Abstract: Methods for forming a thermoplastic film with an attached closure strip are disclosed. The thermoplastic film can then be used to produce zippered reclosable plastic bags. The methods include providing a thermoplastic film web having a sealing surface and providing a closure strip having a binding surface, both being maintained in a non-melted condition at room temperature. A heated thermoplastic binder layer is then extruded and positioned between the sealing surface of the film web and the binding surface of the closure strip very quickly after extrusion. The hot freshly extruded binder layer transfers enough heat to the closure strip and to the film web to melt the binding surface of the closure strip and sealing surface of the film web. Pressure is then applied to the film web and the closure strip to seal the closure strip to the film web. An apparatus for practicing the method at high speed is also disclosed.

Abstract: An object of the invention is to prolong the seal life of a color EL display apparatus. The initial thickness of a light-transmitting main substrate is larger than a predetermined reference thickness WC. First, a plurality of thin-film EL devices are formed on one surface of the main substrate. Then, a sealing substrate having a concave portion formed in one surface thereof is bonded onto the one surface of the main substrate at predetermined intervals. Then, a protective material for protecting the thin-film EL devices is filled in the gap between the one surface of the main substrate and the sealing substrate. Then, the main substrate is processed so as to have the reference thickness WC. Then, a color filter portion is formed on the other surface of the main substrate. Lastly, a reinforcing substrate is attached to the other surface of the main substrate with the color filter portion in between.
