METHOD FOR MAKING UNIDIRECTIONAL CONTINUOUS FIBER-REINFORCED THERMOPLASTIC COMPOSITE MATERIAL
20220168975 · 2022-06-02 ·

Disclosed herein a method for making a unidirectional continuous fiber-reinforced resin composite material. A resin plasticized and molten by an extruder is transported to a coating guide roller through a die head, and a hot-melt resin film layer with uniform thickness is formed on a roller surface of the coating guide roller. Simultaneously, the coating guide roller guides the hot-melt resin to continuously and uniformly coat on a row of flattened unidirectional continuous fibers along the roller surface of the coating guide roller. Subsequently, the coated flattened unidirectional continuous fibers pass through an open dip-coating roller device to effectively combine with the hot-melt resin to obtain a composite material of the hot-melt resin and fibers, which passes through a cooling and forming device to a winder under a driving force of a main traction to obtain the unidirectional continuous fiber-reinforced resin composite material.

Touch fastener and method of manufacturing the same

There is provided a touch fastener that has high followability to the relative movement of portions to be engaged and does not easily separate from a mating member, and thus is usable in a wider range of applications. In the touch fastener, all the elements, that is, first strands, second strands, and engagement elements are formed of a thermoplastic elastomer. Further, the plurality of first strands and the plurality of second strands are disposed to intersect with each other, and consequently, hole portions each surrounded by the two adjacent first strands and the two adjacent second strands are provided. Accordingly, it has a high elastic function, easily stretches, and has high followability to the relative movement of portions to be engaged.

CONTINUOUS MOLDING METHOD AND CONTINUOUS MOLDING APPARATUS OF PRESS MOLDED PRODUCT
20210362390 · 2021-11-25 · ·

A strip-shape softened resin sheet (S) which is continuously extruded from a molten resin extruder is cut to a unit resin sheet and a press molded product is manufactured by press-molding the unit resin sheet in a press-molding machine. Prior to cutting the continuously extruded strip-shape softened resin sheet (S) to the unit resin sheet (U) , the slits C.sub.1, C.sub.2, C.sub.3, C.sub.4 and C.sub.5 which promote the molding to the press molded part from the unit resin sheet (U) (improve an inflow property of the material) are formed by a cutter which is upwardly and downwardly driven by an air cylinder at a portion P.sub.3 in which the material therein is out of a range of the press molded products P.sub.1 and P.sub.2 obtained by press-molding the press molded product by using the press molding machine and becomes a scrap. The inflow property of the resin material for vertical walls and embossment portions when press-molding is improved and the defects of the product can be prevented.
