A molding device including a molding strip formed of a first material and extending along a machine direction, having a width defined along a transverse direction perpendicular to the machine direction, and a thickness measured along a direction perpendicular to the machine direction and to the transverse direction, and an inner face and an outer face, the molding strip including a plurality of cavities, characterized in that part of the cavities are at least partially obturated by a plugging material, so as to define molding cavities for forming retaining elements and/or preforms of retaining elements, and non-functional cavities.

A surface bonding fastener includes first and second members that can be fastened with each other. Each of the first and second members includes a base sheet and a plurality of fastening units on and integrally molded with the base sheet. Each of the fastening units has first and second hooks. The first hook has a first body and a first hook portion. The second hook has a second body and a second hook portion. The first and second bodies are adjacent to each other in a transverse direction and integrally formed on the base sheet. The first and second hook portions are respectively extend from the first and second bodies and bended toward opposite directions. An overlapping degree between the first and second bodies in a longitudinal direction is configured to be determined by a desired fastening strength between the first and second members.

A self-engaging fastener has a flexible base sheet and an array of discrete fastener elements projecting from a broad side of the base sheet. Each fastener element has a stem extending from the base sheet and a head at a distal end of the stem, the head overhanging the base sheet on multiple sides of the stem. The heads of the discrete fastener elements are arranged in a pattern of hexagonal groupings of fastener element heads bordering central regions void of fastener element heads, with each fastener element head spaced from edges of the array being part of three adjacent groupings. The product features a particularly high separation resistance for the area of the product covered by the heads.

A hook-and-loop fastener connector having a plurality of hooks (7) arranged on a base plate (16). The hooks (7) exhibit a hook foot (8) and a hook head (9). The hook foot (8) and hook head (9) are arranged within one plane. The plane (10) and the base plate (16) are angled to each other at an angle (ß) greater than 90°.

Provided is a molded surface fastener capable of stably having high engaging strength with respect to a loop member. The molded surface fastener of the present invention includes a base portion and a plurality of engaging elements provided with a stem portion and an engaging portion, and is formed of synthetic resin containing lubricant at 0.15 wt % or more and 1.00 wt % or less. A top end surface of the engaging element is formed to be flat, and the engaging portion has a hanging portion which hangs down obliquely downward toward the base portion.

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.

In a molded surface fastener in which an engaging element includes at least two engaging pawl portions protruded outward, a plurality of the engaging elements is disposed in a line along a machine direction to form an element row, a plurality of the element rows is arranged side by side in a cross direction, each of the engaging elements has, as the engaging pawl portions, at least a pair of symmetrical engaging pawl portions which are disposed each other at symmetrical positions in the cross direction and are respectively protruded in the cross direction sides, and a plurality of the engaging elements is arranged in a staggered pattern. Thereby, the molded surface fastener can appropriately and stably exert desired performance such as peel strength with respect to more types of non-woven fabrics.

This molded surface fastener includes: a base portion; right and left outer wall portions arranged on the upper surfaces of the base portion; a plurality of engaging elements arranged between the right and left outer wall portions; and right and left magnetic wall portions arranged between the outer wall portions and the engaging elements. This molded surface fastener is molded by melting and integrating first synthetic resin and second synthetic resin that contains magnetic particles. At least each upper end part of the outer wall portions is formed only of the first synthetic resin, while at least each upper end part of the magnetic wall portions is formed only of the second synthetic resin. Consequently, the right and left magnetic wall portions can be formed into predetermined shapes in a stable manner.

A fastening strap is provided, including: a first fastening assembly, including a plurality of hooks and a first stretchable release layer including a first projection projecting beyond a base layer in a first direction, each of the plurality of hooks including a root portion and a curved portion, the curved portion extending from the root portion and curving toward a second direction, the second direction being lateral to the first direction; and a second fastening assembly, including a second stretchable release layer and a plurality of loops; wherein at least one of the plurality of hooks is releasably hooked to at least one of the plurality of loops.

A lock fastener that can be easily manufactured to have great fastening ability includes a touch fastener and a base member insert-molded to the touch fastener. The base member is formed with a space adapted to be filled with a resin material at a time of insert-molding, and the space includes an opening formed in a surface of the base member. The opening is surrounded by a peripheral wall part of the surface. The peripheral wall part is adapted to abut a base of the touch fastener at the time of insert molding and to serve as a bank for preventing the resin material filled into the space from leaking.
