摘要： PURPOSE:To prevent the generation of a vena contracta in a connecting section between the weft and the warp by pressing a plastic material in the direction of extrusion on the return of a pushing tool for the plastic material forwarded in a weft molding process. CONSTITUTION:A plastic material is extruded through a groove 121 for molding the warp formed between a pair of molding dies 11, 12, and the warp 2 is molded. A clearance 15 for molding the weft is formed between said dies 11, 12 during the molding of the warp 2 while a pushing tool 14 for the plastic material is forwarded in an extruding path for the plastic material connected to said groove 121 and clearance 15. Consequently, the plastic material is extruded from said clearance 15, and the weft 3 is molded integrally together with the warp 2. The pushing tool 14 is returned and returned to an original position while the clearance 15 is closed, and the molding of the warp 2 is started. The plastic material is pressed on the return of the pushing tool 14.

摘要： PURPOSE:To improve the slip preventing property of a composite object, providing an unevenness to the surface of a substrate, by lapping a fibrillated plane object to a planar object to become the substrate so as to be shifted relatively to a direction different from a proceeding direction when sticking them together. CONSTITUTION:While a foamed, fibrillated plane object 12 is obtained by using an extruder, extruding from a T-die at ca. 230 deg.C a compound composed of ca. 99wt% of a low density polyethylene and ca. 1wt% of a foaming agent, an azodicarbonamide as the raw material of the foamed, fibrillated plane object and foaming, fibrillating, a film 13 is obtained by extruding a single polypropylene at ca. 250 deg.C, using another extruder. Then, a composite film 16 is obtained by introducing both, being in an unsolidified state, to a casting roll 14 of which the surface temperature is 95 deg.C, shifting relatively at an amplitude of ca. 3cm so as to reciprocate once a ca. 10cm of an advance, lapping, sticking together, cooling and solidifying.

摘要： PURPOSE:To provide a metallic pipe with a rugged coated film of a synthetic resin, by vibrating a molten synthetic resin or intermittently chaning the feed rate of a metallic pipe when coating the pipe with the resin. CONSTITUTION:An adhesive 3 such as a modified polyethylene resin base adhesive is preliminarily coated on the outside surface of the metallic pipe 2, and a molten synthetic resin 5 is extruded through a circular die 1. The die 1 is fitted with an extra low frequency vibration genrator 4 and is vibrated, whereby a complicated transverse wrinkle form rugged pattern is generated in the resin 5 being extruded, and the rugged pattern remains as it is at the surface of the resin after the resin is coated on the pipe 2. Alternatively, the rugged pattern is formed on the surface of a coated film 5 of the synthetic resin by a method wherein feed rools 6 for the metallic pipe 2 are alternately rotated forwardly and reversely when coating the resin on the pipe 2.

摘要： PURPOSE:To manufacture the captioned molded body having a uniform and minute cell structure by pressing an organic-solvent foaming agent into a vinyl chloride resin composition for foam molding which is made gelled by heating in an extruder and by performing later foam molding by extrusion while giving vibrations thereto. CONSTITUTION:The resin composition formed of the vinyl chloride resin of 100pts. (weight part: the same is applied in the following), a nucleus forming agent of 0.01-40pts. whose average particle diameter is about 30mu or below, a plasticizer (ex. dioctylphthalate) of 5-100pts., acrylic resin (preferably emulsion polymer) of 0.5-30pts. and a resolving-type foaming agent (ex. azodicarvoneamido) of 0- 20pts. is made gelled by heating in the extruder and thereafter the organic-solvent foaming agent (ex. butane, trichlorofluoromethane, etc.) of 1-30pts. whose boiling point as 90 deg.C or below is pressed in the composition. Next, while vibrations being given to the dies of the extruder (or an extruded substance just after being extruded from the dies), the redin composition is subjected to foam molding by extrusion.
