A dry adhesive and a method of forming a dry adhesive. The method includes forming an opening through an etch layer and to a barrier layer, expanding the opening in the etch layer at the barrier layer, filling the opening with a material, removing the barrier layer from the material in the opening, and removing the etch layer from the material in the opening.

The present invention relates to a molded hook fastener having excellent fire retardancy and low fuming property, and having a substrate and a large number of engaging elements projecting from a surface of the substrate, wherein both the substrate and the engaging elements contain a resin composition in which a polyester-based elastomer resin (A) and a polyetherimide-based resin (B) are mixed with a weight ratio (A)/(B) in a range of 2/98 to 70/30.

A method of making a laminated touch fastener includes introducing a flexible substrate to a resin applicator, applying flowable resin to a limited region of a surface of the substrate, and molding the applied resin to form a plurality of defined structures extending from a layer of the applied resin. The substrate surface, as the substrate is introduced to the resin applicator, has a surface characteristic that varies across the surface. The surface includes both a first region and a second region adjacent the first region, the surface characteristic varying to a greater degree within the second region than within the first region. The flowable resin may be applied within the first region such that an edge of the resin layer is disposed within, and adjacent an exposed portion of, the first region of the substrate surface.

A hook fastener includes a stem having two lateral edges, a first surface, and a second surface. A cap extends from an upper end of the stem, and the cap includes an upper surface, a first end, a second end, and a pair of overhanging portions. The upper surface of the cap is sloped between the first end and the second end. The first and second ends are at opposite longitudinal ends of the cap, and each overhanging portion extends in a lateral direction from the stem.

A surface fastener molding apparatus includes a supporting structure and a second supporting structure for axially supporting a mold roll in a rotatable manner at a first end side and a second end side of the mold roll which is opposite to the first end side. The mold roll includes a circumferential surface in which a plurality of mold cavities for molding engaging elements of the surface fastener is provided. A first linear driving means and second linear driving means are provided which are for, respectively, advancing or retracting the first supporting structure and the second supporting structure. The degree of closeness between the extruding nozzle and the mold roll is regulatable across the first end side and the second end side of the mold roll, based on at least one activation of the first driving means and the second driving means.

An aspect of the present invention relates to a wrapping tape for repelling insects, the wrapping tape having a number of male engagement elements on a front surface of a tape, and a number of loop-shaped engagement elements on a rear surface of the tape, wherein the male engagement elements and the loop-shaped engagement elements can be engaged each other, and an insect repellent component is applied at least to the front surface of the tape and the male engagement elements.

Described is a fastening tape that includes a plurality of attachment portions extending upwardly from a bottom portion of the fastening tape. The fastening tape also includes at least one inner wall disposed adjacent to at least some of the plurality of attachment portions and at least one outer wall offset from the at least one inner wall such that a cavity is disposed between the at least one inner wall and the at least one outer wall. Finally, the fastening tape includes an injected foam member disposed in the cavity.

A vehicle cover assembly comprising; a flexible cover; one or more side rails; and a fastener assembly that is secured to a vehicle bed comprising; a cover fastener that is on one or more edge regions of the flexible cover; and a side rail fastener with one or more rows of fasteners comprising; a plurality of dual hooks on the base that releasably connect with the cover fastener of the flexible cover; and a plurality of spacers between the plurality of dual hooks.

A fastening tape with a flange is provided. The fastening tape includes a body and a plurality of fasteners positioned on the body. The flange is between the plurality of fasteners and an edge of the body. In some cases, the flange increases the hook to foam strength of the fastening tape when the fastening tape is within foam.

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.
