Abstract: Molten resin is continuously extruded from an extrusion nozzle having a selected width, and at the same time, a plurality of parallel fiber filaments are introduced straightly toward the molten resin outlet in a direction along rotation of a die wheel and/or traversing one or more filaments by a predetermined width. The molten resin extruded from the extrusion nozzle and the filaments are introduced into a predetermined gap for molding a plate-like substrate sheet between the nozzle and the die wheel, which has a multiplicity of hook-forming cavities in its circumferential surface and is rotatable in one direction, and at the same time, the hook-forming cavities are filled with a part of the molten resin. The filaments are embedded in the substrate sheet of the extruded molten resin as the die wheel is driven to rotate in the direction of extrusion of the molten resin, and a plurality of hooks are continuously molded on a surface of the substrate sheet.

The engaging miember comprises a flat substrate sheet, first engaging elements having a stem and an engaging portion disposed at the top thereof and second engaging elements having a column portion and a tilted hitch portion also disposed at the top thereof, the first engaging elements and the second engaging elements being arranged in linear rows independently relative to each other.

Abstract: A disposable diaper has a pair of first surface fastener members supported by a rear flap of a diaper body and a second surface fastener member supported by a front flap of the diaper body. The first and second surface fastener members have first and second engaging elements; the first and/or second engaging elements are made of water-soluble resin. After approximately 1/3 to 2/5 of the diaper body on the side of the rear flap is folded inwardly, the diaper body is wound into a roll toward the front flap, and then the water-soluble resin of the first and/or second engaging elements is dissolved with water. Then the first surface fastener members are pressed against the second surface fastener member to fasten the diaper body in roll as waste.

In a separable fastener composed of a base part and a multiplicity of engaging elements raised from the obverse side of the base part, a water-soluble resinous material is present at least on the reverse side of the base part. Advantageously, a resin which manifests adhesiveness on absorbing water is used for the water-soluble resinous material. In another mode of the separable fastener, the base part and the engaging elements are made of a water-soluble resinous material and/or a biodegradable resin.

Abstract: A molded surface fastener is manufactured by supplying molten resin to the circumferential surface of a die wheel rotating in one way to mold a substrate sheet blank and a multiplicity of substantially straight and inclined engaging element blanks in an integral form, and then pressing distal ends of the engaging element blanks by a heat-molding roller in rotation at the same speed to incline the engaging element blanks further toward the substrate sheet blank and also to melt the distal ends to shape each said distal end into an engaging head projecting in a direction opposite to the direction of inclination of the respective engaging element blank. Each of the resulting engaging elements is composed of a stem rising from the substrate sheet surface with inclination by a predetermined angle (.theta.

Abstract: Disclosed are a biodegradable separable fastener which can be appropriately used as a fastening means for disposable products and a method for the production thereof. In a separable fastener composed of a base part and a multiplicity of engaging elements raised from the obverse side of the base part, the base part and the engaging elements are formed of a biodegradable resin. In a favorable mode, at least the base part of the separable fastener has such a sectional shape as to increase the specific surface area. For example, grooves and/or holes are formed in the base part or holes are extended from the reverse side of the base part to the interiors of the engaging elements.

Abstract: A surface fastener molded of synthetic resin, comprises a substrate sheet, and a multiplicity of hook elements molded on at least one surface of the substrate sheet, each hook element having a hook body having a stem and a curved portion. Each of the hook elements has first and second reinforcing ribs projecting from opposite side surfaces of the hook body. The first reinforcing rib is greater in height than the second reinforcing rib. In the presence of the first and second reinforcing ribs different in height, compression stresses developed in the hook body are dispersed at two or more points when a companion engaging element is removed off the hook element.

Abstract: A fastening connector of thermoplastic resin for connecting two separate members together is continuously molded efficiently in a single step by a simple method and apparatus. The method includes the steps of continuously extruding molten resin from an injection nozzle to the circumferential surface of a die wheel, which has in the circumferential surface, a multiplicity of engaging-element-forming cavities, to continuously mold a substrate sheet between the circumferential surface of the die wheel and the injection nozzle and a multiplicity of engaging elements in the engaging-element-forming cavities which elements stand on a front surface of the substrate sheet and, at the same time, to continuously mold at least one engaging ridge, through an engaging-ridge-molding channel, with part of the molten resin integrally with a rear surface of the substrate sheet.

Abstract: A molded surface fastener comprising a substrate sheet, and a multiplicity of engaging elements molded in rows on one surface of said substrate sheet. Each of the engaging elements has a pair of stems standing from the one surface of the substrate sheet, and a pair of hooks extending in opposite directions from distal ends of the stems and formed in a pair of parallel planes perpendicular to the general plane of the substrate sheet on opposite sides of the central line of the pair of stems. When companion loops are disengaged from the engaging element, the individual hooks are angularly moved about the central line of the pair of stems in a horizontal plane independently of each other and, at the same time, are expanded upwardly. As a result, the loops and the engaging element can be disengaged from one another smoothly without any damage.

Abstract: A fastening device molded of a synthetic resin material and adapted to be engaged with a large number of loops on one surface of a fastener part of a mating member includes a base member having on its one surface a large number of hooks integrally molded with the base member and arranged in a plurality of rows. The hooks in each hook row generally have the same hook direction aligned with an axis of the hook row, and the hooks in one hook row and the hooks in an adjacent hook row do not always have the same hook direction. At least one hook in each hook row which is adjacent to a peripheral edge of the base member have a hook direction facing outwardly away from the peripheral edge. With this arrangement, the hooks located adjacent to the peripheral edge are capable of withstand undue force tending to fatigue and eventually break the hooks.
