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 shaped hook member of hook-and-loop fastener including a base plate and a plurality of hook-type engaging elements that rise from a surface of the base plate. The hook-type engaging elements are each tapered from the proximal end to the distal end, and are each curved from a point in the course from the proximal end to the distal end, and the distal end is directed toward the base plate. The plurality of hook-type engaging elements are arranged in rows extending in the same direction as the curving direction of the hook-type engaging elements, and the curving directions of the hook-type engaging elements in two adjacent rows or two adjacent units each of two or more rows are opposite to each other. The base plate and the hook-type engaging element are formed of a semi-aromatic polyamide resin containing a semi-aromatic polyamide and an elastomer.

Aspects disclosed herein relate to forming on a substrate fastener elements suitable for use in touch fastener by employing vibration forming methods. The processes described provide for a greater flexibility in manufacturing than prior methods and overcome certain limitations in prior forming techniques. Further, the product made can embody a variety of different configurations suitable for a given application. Employing vibration forming methods, such as ultrasonic forming methods, allows for the use of a wider variety of substrate material than materials used with convention methods of touch fastener formation.

Arrays of male fastener elements are formed by molding preforms in cavities defined in one or more adjacent plates and shaped to mold preform arms that extend to a plate side, such as in a cross-machine direction of a continuous molding process. The preforms may be deformed to flatten their upper surfaces and lengthen the arms. Stems of preforms have molded side surfaces and each have width, measured in the longitudinal direction of the strip, that narrows with distance from the strip surface, and also narrows with distance from a parting line extending from the strip surface to the head between the arms.

A fastening tape having flexibility in a longitudinal direction of the fastening tape. The fastening tape includes a plurality of fasteners, a support, and magnetic material positioned on the support. The support defines a plurality of plateaus and a plurality of valleys. The magnetic material is positioned on at least a portion of one of the plurality of plateaus or the plurality of valleys of the support such that a height of the magnetic material varies in the longitudinal direction. Because the height of the magnetic material varies, the fastening tape is more flexible in the longitudinal direction. In some cases, the fastening tape is also flexible in the lateral direction.

A transversely extensible continuous elastic laminates includes a continuous elastic tape sandwiched between two continuous webs, and at least one row of tabs extending transversely outside the two webs, wherein the tabs are made of a non-woven material and have respective micro-hook formations integrally formed in the non-woven material forming the tabs.

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 laser weldable hook-and-loop fastener contains a laser light transmitting male-type molded hook-and-loop fastener (A) and a laser light absorbing layer (B) formed of a thermoplastic resin, which is integrated on the back surface of the male-type molded hook-and-loop fastener (A). The male-type molded hook-and-loop fastener (A) has a base plate and a large number of male-type engaging elements rising from the surface of the base plate. The male-type engaging elements and the base plate are formed of the same resin selected from a polyester elastomer and a polyamide, the male-type engaging elements are arranged in a row, and the laser light absorbing layer (B) has an infrared absorptance of 85% or more at a wavelength of 980 nm.

Provided is a molding apparatus used for manufacturing a molded surface fastener wherein a die wheel driving rotationally has a concentric double cylinder structure provided with an outer side cylindrical body that has provided therethrough a plurality of penetrating holes, and an inner side cylindrical body that has formed, in the outer peripheral surface thereof, a plurality of grooved portions, the grooved portions located in the inner side cylindrical body include a use grooved portion that intersects with the penetrating hole of the outer side cylindrical body and a non-use grooved portion that is covered by the inner peripheral surface of the outer side cylindrical body. By using this molding apparatus obtained is a molded surface fastener in which a plurality of types of engaging elements having different shapes in a plan view are arranged cyclically in a reference direction.
