Jun 16, 2017

   Improved hooks for hook and loop fasteners, especially molded plastic hooks for use with dwarf rings. Shackle fastener technology is well known in which the fastener comprises two separate strips which have interconnected tufts on the strip surface. Wherein one of the tufts has a plurality of annular elements and the other pile has hook elements which can interact to form a separate connecting member.Hook And Loop

    This pile fastener is widely used in situations where it is easy to open and close, such as for clothing, footwear, furniture, medical supplies, automotive fasteners and many other industrial sites, where separate or permanent connections are required. U.S. Patent No. 3,009,235, US-3,083,737, US-3,154,837 disclose various forms of separable pile fastener strips which are made from synthetic fibers such as nylon fibers as raw materials, through basic textile processing Technology made. This processing method creates a base fabric in which the surface of the pile is woven, and the tuft surfaces can be connected to each other to form a latching mechanism. For a long time, has been using molded plastic processing technology to create a special hook material, in the forming strip, and then make the hook and the bottom belt into one.Hook And Loop

    U.S. Patent No. 3,031.730 discloses a latching mechanism in which a plurality of piercing elements are exposed on a surface material in contact with a front face of a knitted fabric, which is a cast or molded flexible or plastic hook Pieces. U.S. Patent No. 3,760,000 to Menzin discloses a hook "ring" having an inclined surface acting as a die surface for drawing the molded hook from its mold cavity. The surface of the hook body has two flat plate-like sides of the same size and a slightly larger third side. The cross section of the hook body portion in the vicinity of the belt is larger than the cross section of the hook portion and the three flat sides of the hook body enter and pass through the entire hook portion in a smooth curve so that the three sides Of the hook part of the hook and the composition of the same continuous surface, as the corresponding part of the continuation of the hook. U.S. Patent No. 3,312,583 to Rochlis and U.S. Patent No. 3,708,833 to Ribich describe another embodiment of a hook in which the shape of the hook is slightly tilted. U.S. Patent No. 3,913,183 to Brurnlik describes a self-clamping device wherein the clamping element is particularly suitable for automatically clamping fibers or the like along the entire length of the fiber.
