A loop surface fastener in which numerous looped engaging elements formed from loop yarns inserted in parallel to ground warp yarns are provided upright on one side of a base fabric formed from ground warp yarns and ground weft yarns satisfies all the following requirements 1) to 3). 1) The loop yarn is a multi-filament yarn formed by bundling 5 to 9 filaments of 30 to 45 decitex. 2) The density of the looped engaging elements is in a range of 100 to 200/cm.sup.2. 3) Loop surfaces of the looped engaging elements are substantially facing in the same direction and the loop surface facing direction is a ground weft yarn direction.

A fastening element (1) is provided having a gripping portion (5), a plurality of gripping elements (20, 20) extending from the gripping portion (5), a supporting portion (10) being defined by at least one supporting-portion wall extending from the gripping portion (5) in a direction opposite that of the gripping elements (20, 20), the supporting portion (10) having a supporting-portion width smaller than a gripping-portion width of the gripping portion (5), such that a top flange is formed by the gripping portion (5) relative to the supporting portion (10) on at least one side of the fastening element (1), and an anchoring portion (15) extending from a distal end of at least one supporting-portion wall and parallel to the gripping portion (5) so as to form a bottom flange relative to the supporting portion (10) on the at least one side corresponding to the top flange.

In this molded surface fastener, plural engaging elements having a stem portion and an engaging head portion formed integrally on the stem portion are standing on the base portion, at least one pawl portion having a pawl width dimension narrower than a width dimension at a boundary between the stem portion and the engaging head portion is protruded on an outer peripheral edge part of the engaging head portion, and a back surface of pawl of the pawl portion is formed at different angles with respect to a back surface of head portion of the engaging head portion. Such a molded surface fastener of the present invention has a substantial engaging force with respect to a female surface fastener and can make a texture of its surface comfortable.

A pressure-sensitive adhesive fastener (100) is overlapped with a target object (150) on one surface (110a) side provided with a pressure-sensitive adhesive layer (121) and protruding members (130) to be coupled with the target object (150). With the pressure-sensitive adhesive fastener (100) coupled with the target object (150), the pressure-sensitive adhesive layer (121) is bonded to the target object (150), and part of column sections (131) and insertion sections (132) of the protruding members (130) enter gaps in the target object (150). This entrance creates such a mode that the protruding members (130) are stuck into the target object (150), resulting in a prevention of a shift in position between the pressure-sensitive adhesive fastener (100) and the target object (150).

In this molded surface fastener, an engaging element includes a columnar stem portion, and micro pawl portions protruding outward from an upper end outer peripheral edge of the stem portion in a plan view of the engaging elements. A pawl width dimension of the micro pawl portions is smaller than a line segment connecting two points on the upper end outer peripheral edge of the stem portion. The micro pawl portions protrude toward a base portion. This molded surface fastener has a high peel strength and a shear strength with respect to a female surface fastener.

Embodiments related to a touch fastener and its methods of manufacture and use are disclosed. In one embodiment, the touch fastener may include a substrate with a first portion and a second portion displaceable relative to the first portion. A first fastening element may be formed in the first portion. When the first portion is displaced relative to the second portion, a force and/or moment generated by the displacement may cause the first fastening element to be deployed.

This manufacturing method of a molded surface fastener involves a primary molding step for forming a primary molded body and a secondary molding step for compressing a provisional element of the primary molded body while heating the same. A molding apparatus is provided with a mold member comprising multiple penetration holes and multiple concave portions, whereof each penetration hole communicates to at least one concave portion; in the primary molding step, the molding apparatus is used to form a primary molded body comprising a provisional element having a primary stem portion and a pawl portion is formed from the protruded portion by compressing the provisional element. By this means, it is possible to stably manufacture a molded surface fastener that has an engaging element comprising a pawl portion that projects from the outer peripheral edge of an engaging head portion.

A device incorporating both a magnet and a living hinge may be employed to construct cases to protect electronic devices and to function as a closure for cases and lidded containers. Such cases often can be bent three 360? allowing the cases to be either closed protecting devices therein are closed upon themselves allowing the case to function to secure an electronic device to a substrate such as an article of clothing. The devices of the disclosure can also be used to organize and hold loose items together.

A hook-and-loop type tear-off device having a first part with loop elements and a second part with hook elements is provided. A first multi-layer adhesive is hot-applied to the first part, the first multi-layer adhesive having an inner layer and an outer layer made of thermoplastic polyurethane.

An attachment system for supporting holders on a carrier includes a platform having a front side, an opposite back side, the platform being constructed of laminated layers having slits therethrough defined and bound by opposite edges of the layers fused together to increase wear and abrasion resistance of the edges, the slits arranged in a predetermined pattern of aligned and spaced apart rows, the slits being configured to receive straps therethrough between the front side and the back side to attach at least one holder to the platform, and the platform being supported by and comprising an element of a carrier configured to be worn against a portion of a user's body, the back side and at least one element of the carrier or a backing element defining and bounding a generally flat cavity through which the back side can be accessed.
