There is provided a male engaging member of a surface fastener comprising novel engaging elements that are flexible to a certain extent and highly durable and, at the same time, ensure a certain level of peeling resistance. The engaging elements of such an engaging member stably remain in engagement with piles of a female engaging member coupled with it without unintentionally becoming disengaged from the piles caught by them. 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. The height of the second engaging elements as measured from the surface of the substrate sheet to the top thereof is about twice as large as the height of the first engaging elements from the bottom to the top thereof. All the hook-shaped engaging portions and all the tilted hitch portions extend in the same direction in one row, the direction being opposite to the extending direction in adjacent rows.

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.1), and an engaging head projecting from an upper end of the stem in a direction opposite to the direction of inclination of the stem, an extension line of the engaging head crossing the substrate sheet surface at a predetermined acute angle (.theta.2).

The present invention provides a disposable diaper, which is easy to put on the wearer, and which is possible to be put on easily when the wearer is standing on both legs. The disposable diaper including a diaper body having a hip portion and a belly portion, which are spread out with a crotch portion between them. The disposable diaper includes engaging means, which are arranged to be attachable/detachable, on the both side portions of the hip portion and the belly portion. The engaging means have hook elements which are disposed on the hip portion and projecting toward the belly portion, engaging faces disposed on the hook elements and facing to the hip portion, hook elements which are disposed on the belly portion and projecting toward the hip portion and engaging faces disposed on the hook elements and which are facing to the belly portion. At least one of the hook elements is sandwiched between the hook elements, so that the engaging faces come into contact with each other to engage the hook elements each other.

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.

The present invention provides a disposable diaper, which is easy to put on the wearer, and which is possible to be put on easily while the wearer is standing on both legs. The disposable diaper according to the present invention includes a diaper body having a hip portion and a belly portion, which are spread out with a crotch portion between them. The diaper further includes male members which are protrusively arranged from side portions of one of the hip portion and said belly portion in a face direction and female members, which are arranged on side portions of the other and in which the male members engage in a face direction of the side portions. The female members are provided with receiving portions in which the male members are inserted in a face direction of the side portions. Engaged surfaces perpendicular to the inserting direction of the male member are formed on the inner walls of the receiving portions and the male members are provided with engaging surfaces opposing to the engaged surfaces.

This invention provides a fixture for an abrasive cloth paper in which a surface fastener does not have to be bonded prior to fixing of the abrasive cloth paper onto the fixture and in which hook-shaped engaging elements are disposed accurately at portions directly related to polishing by an abrasive cloth paper fastening portion of the fixture with precedence. A fixture made of synthetic resin comprises a mounting portion which is engaged with/disengaged from a base plate of a sander and a fastening portion on which an abrasive cloth paper is wound and fastened. In the fastening portion, a plurality of surface fastener engaging element rows which are parallel to a direction of winding of the abrasive cloth paper are formed integrally so as to form a fastening surface. A hollow portion is formed in the fastening portion. Consequently, a complicated work for bonding a male surface fastener to the fixture integrally is eliminated and surface fastener engaging element rows can be arbitrarily formed integrally at required portions on a surface of the fastening portion of the fixture. As a result, the fastening surface composed of the surface fastener engaging element rows can be formed accurately only at portions in which a fastening strength with respect to the abrasive cloth paper needs to be ensured, and no fastening surface FS is formed in a portion not requiring the fastening-strength, thereby leading to reduction of production cost.

A fastening surface body which can mount a sheet-like fastening body to a sheet-like mounting body having various kinds of cross-sectional shapes with no play. The fastening surface body can securely engage a surface fastener of a sheet member to which a female surface fastener is mounted, where the fastening body includes a flat substrate having a surface comprising male engaging elements. The fastening body is structured so as to be fitted and fixed to fitting groove portions of the mounting body so as to bond and fix various kinds of sheet members. Each fitting groove portion of the of the mounting body generally has a C-shaped cross section formed with openings along both end edges of a widthwise direction. The fastening body has at least a protrusion having a height so that that the protrusion contacts a surface of the mounting body when the fastening body is fitted and fixed to the mounting body. The protrusion also extends in parallel to the fitting groove portions at least at a center portion in a widthwise direction on a surface opposite to the surface from which the male engaging elements protrude. Accordingly, it is possible to mount the sheet-like fastening body with no play even when the fastening body is thinner than a height of the opening of the fitting groove portions of the mounting body. Further, the protrusions can support the fastening body in a horizontal state against an external pressing force.

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.
