A magnetic buckle device has a first base, a second base, a first component mounted to the first base, a second component mounted to the second base, and a lock mechanism. A magnetic attraction force is generated between the first component and the second component to move the first base and the second base toward each other. The lock mechanism is connected to the second base and has a locked status and an unlocked status. The lock mechanism has an engaging component and an unlocking component. In the locked status, the first base and the engaging component engage with each other such that the first base and the engaging component are inseparable. In the unlocked status, the unlocking component is capable of being operated to allow the first base and the engaging component to disengage from each other.

A double-face fabric having elastic properties in its warp direction and provided with hook-and-loop properties, formed by the weaving of warp yarns and of weft yarns. The warp yarns are of four different types worked in different weaves with respect to the weft yarns, respectively: elastic yarns (A) worked in a taffeta weave; core yarns (B), formed of synthetic yarns texturized by false twist on the face, worked in a plain weave alternating with surface floats and having a linear strand density in the range from 10 to 25 dtex; core yarns (C) on the back side, formed of multifilament synthetic yarns, having a linear strand density in the range from 0.3 to 1.7 dtex, worked in a rep weave, alternating floats of great length on the back side and short binding areas on the face side, binding yarns, exclusively formed of thermo-adhesive synthetic yarns, having a melting point in the range from 80° C. to 160° C., worked in a plain weave.

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.

The present invention relates to rolls of an elongated material and to methods of manufacturing fastening tabs.

A male-type molded hook-and-loop fastener-equipped sheet includes a male-type molded hook-and-loop fastener and a non-foam resin sheet integrated on the back surface of the male-type molded hook-and-loop fastener. The male-type molded hook-and-loop fastener includes a resin-made base plate and a plurality of male-type engaging elements made of the same resin, rising from the surface of the base plate and arranged in a row. The male-type engaging elements are bent in the direction of the row direction of the male-type engaging elements from the middle thereof, where the tip end portion approaches the base plate. The non-foam resin sheet is directly laminated and integrated on the back surface of the male-type molded hook-and-loop fastener. The resin constituting the non-foam resin sheet is a resin mainly composed of an elastomer resin of the same type as the resin constituting the male-type molded hook-and-loop fastener, though with a lower hardness.

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 method of manufacturing an article may include loading a soluble bobbin thread into an embroidery machine and then driving a needle thread through a base sheet with a needle of the embroidery machine according to a programmed first pattern that provides a series of loops of the needle thread extending outward from a bobbin side of the base sheet. The method may further include bonding the needle thread to a needle side of the base sheet opposite from the bobbin side. A spacer layer may be disposed at the bobbin side of the base sheet, and may be removed after the needle thread is bonded to the base sheet. The loops may be loops of a hook-and-loop fastener or ball control features in various articles manufactured according to the method.

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.

A mesh hook surface fastener does not lose engagement ability even when subjected to mold-in forming and gives only a slight feeling of something foreign. The mesh hook surface fastener contains first shape holding ribs (a.sub.21) with a relatively small protrusion height and second shape holding ribs (a.sub.22) with a relatively large protrusion height which protrude to the opposite side of hook-shaped engagement elements (B.sub.1, B.sub.2) across a base layer (A.sub.1) and are alternately arranged. The heights of the adjacent shape holding ribs (a.sub.21, a.sub.22) are different, which prevents the direct entrance of a foamable resin liquid and weakens its force. As the force weakens, foaming and curing progress more readily and, as a result, the amount of the foamable resin liquid that passes through meshes of the base layer to reach the hook-shaped engagement elements can be reduced.
