Abstract: A particle board manufacturing method capable of manufacturing particle board of a thickness of 1 to 10 millimeters of fine or coarse chips, which includes a filling machine and a press wherein the press comprises a heatable platform for conveying the chip-resin mat from a filling machine to a press in a simple and efficient manner and without causing any distortion of the mat.

Abstract: Apparatus for molding products from polymeric material comprising cooperating mold elements forming a mold cavity for receiving polymeric material to be molded, means for introducing steam into thermoconductive relationship with the respective mold elements and separate valved conduits through which the steam in thermoconductive relationship with the respective mold elements is discharged. Also a method of molding products from polymeric material comprising introducing polymeric material into a mold cavity formed by cooperating mold elements, causing steam to flow in thermoconductive relationship with the respective mold elements and separately controlling the duration of such steam flow in thermoconductive relationship with the respective mold elements.

Abstract: Apparatus for molding products from polymeric material comprising cooperating mold elements forming a mold cavity for receiving polymeric material to be molded and means for optionally introducing steam into thermoconductive relationship with the respective mold elements in parallel and in series. Also a method of molding products from polymeric material comprising introducing polymeric material into a mold cavity formed by cooperating mold elements, causing steam to flow in thermoconductive relationship with the respective mold elements in parallel during a portion of the molding cycle and causing steam to flow in thermoconductive relationship with the respective mold elements in series during another portion of the molding cycle.

Abstract: Hollow articles such as bottles and containers are formed from tubular, elongated injection molded preforms made of thermoplastic material and having a finished neck portion adjacent an open end and a closed end body portion which method comprises annealing said preform by heating the portion of the preform body adjacent the neck to a temperature just below or about the Tg (glass transition temperature) for such material while maintaining the remainder of the preform body at a significantly lower temperature, for a sufficient time to essentially relieve the internal stresses in said body portion adjacent the neck, such annealing step being applied prior to the thermoforming of said preform into the hollow article.

Abstract: The present invention relates to plastic extruded strapping and its processing techniques. More particularly, it is concerned with polyester extruded strapping of high tensile strength and low elongation at break to replace steel strapping. Although not limited thereto, this invention is of primary importance in connection with the technique of crystallization and orientation of polyester predominantly in one direction in the making of strap characterized by two-step stretching. Furthermore, this invention is related to the design of a multi-purpose extrusion line for the processing of strap of various polymeric materials.
