A system for fastening a covering on a surface includes a first assembly comprising a first retaining element; and a second assembly comprising a second retaining element; the first and second retaining elements being configured to engage each other so as to form a reversible bond; the system being characterized in that the first retaining element comprises an array of retaining elements comprising hooks having a height (Hc) lying in the range 0.05 mm (0.0020 in) to 1 mm (0.039 in), and the second retaining element comprises an array of retaining elements comprising loops having a height (Hb) lying in the range 0.1 mm (0.0039 in) to 3.0 mm (0.12 in).

A fastening device has a first fastening member with a plurality of teeth and a second fastening member with a plurality of sockets which are sequentially engagable in tooth and socket pairs in an engagement direction by relative rotation of the tooth and socket. Each tooth has a first surface and a second surface fixed relative to the first surface. Each socket has a recess defined by a first wall and second wall fixed relative to the first wall. Upon engagement, the first and second surfaces of the tooth abut the respective first and second walls of the recess and prevent relative movement of the tooth in the engagement direction and a portion of the first wall of the socket closely abutting the first surface of the tooth is disposed between the tooth and a portion of the first fastening member and prevents relative separation of the tooth and socket.

A connection system has a first adhesion segment, on which a first connection region is formed, a second adhesion segment, on which a second connection region is formed, and a solidifiable liquid connection substance for connecting the two adhesion segments in a material fit, wherein at least one of the two connection regions is formed flexibly, such that, when the liquid connection substance is introduced between the two connection regions which are opposite one another in an assembly arrangement of the two adhesion segments, a material connection is formed between the two connection regions automatically as a result of the elastocapillary effect via the liquid connection substance.

A molding apparatus includes a movable molding surface with molding cavities, a pressure shoe with a stationary outer surface that defines in cooperation with the molding surface a pressure zone, and a resin source configured to introduce molten resin into the pressure zone to be forced into the molding cavities by pressure in the pressure zone. The molding surface is movable with respect to the pressure shoe to introduce molding cavities to the pressure zone to be filled with resin while the outer surface of the pressure shoe and the molding surface define in between an entrance gap of decreasing width upstream of the pressure zone. The outer surface of the pressure shoe is spaced from the molding surface in the pressure zone to define a minimum gap at which the outer surface of the pressure shoe has a slope parallel to the molding surface. The pressure shoe is adapted to be held in a flexed condition against resin in the pressure zone while forcing resin into the cavities, with the outer surface of the pressure shoe curved upstream of the pressure zone.

A method of making a mechanical fastener. The method includes providing a slit web having mechanical fastening elements, applying tension to the slit web in the machine direction, and spreading the slit web in the cross-machine direction by moving the slit web over a crowned surface to provide a spread mechanical fastening web. The slit web includes a plurality of interrupted slits that are interrupted by intact bridging regions of the web. The crowned surface may be an air bearing, or at least a portion of the crowned surface is a low-friction surface, and the crowned surface and the slit web are not moving at the same speed in the same direction. The crowned surface may be provided with at least one ridge.

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 fastening device has a first fastening member with a plurality of teeth and a second fastening member with a plurality of sockets which are sequentially engagable in tooth and socket pairs in an engagement direction by relative rotation of the tooth and socket. Each tooth has a first surface and a second surface fixed relative to the first surface. Each socket has a recess defined by a first wall and second wall fixed relative to the first wall. Upon engagement, the first and second surfaces of the tooth abut the respective first and second walls of the recess and prevent relative movement of the tooth in the engagement direction and a portion of the first wall of the socket closely abutting the first surface of the tooth is disposed between the tooth and a portion of the first fastening member and prevents relative separation of the tooth and socket.

Locking mechanisms and electronic devices having locking mechanisms are described herein. In one example, a locking mechanism includes a latch configured to move between a locked position and an unlocked position, wherein a component of the electronic device is secured in the locked position and removable in the unlocked position. The locking mechanism further includes a memory wire in communication with the latch, wherein the memory wire is configured to contract in length to move the latch between the locked position and the unlocked position to release the component of the electronic device.

Device for closing the opening of a sack, in particular a sack made of flexible material, including a first element with hooks and a second element with hooks, the hooks (9) of the two elements engaging into one another to achieve the closure of the opening, each element with hooks including a base strip (7, 8) and hooks coming from the strip.

A fastener member for mechanical affixation to a structure includes a base having first and second sides, a plurality of fastening elements integrally formed and extending from a first side of the base, and at least one affixation element extending from the second side of the base and arranged to mechanically affix to an attachment opening of a structure. A system includes a structure and a fastener member for mechanical affixation to the structure. A method includes affixing the fastener member to a structure.
