摘要:
The invention provides a slide fastener comprising a fastener element in which a metallic coating layer is formed, the metallic coating layer being never scraped by a sliding of a slider. In a coil-shaped fastener element (1) made of synthetic resin, a metallic coating layer (20) is formed on the surface of a leg portion (7) except an inverted portion (9) and a coupling head (6) with which a guide flange and a guide post of a slider come into contact. Therefore, no metallic coating layer (20) is formed on a portion with which the guide flange and guide post of the slider come into contact. As a result, such an event that the metallic coating layer (20) is scraped and that metallic powder is scattered is prevented, so that a fastener element having a beautiful metallic gloss can be used for a long term and a cheap, fashionable slide fastener is obtained. This invention can be applied to zigzag type, injection molded type and metal type fastener elements.

A coil-shaped fastener element (2) is comprised of a coupling head (4) bulging to both sides, upper/lower leg portions (5, 6) adjacent the coupling head (4) and a connecting portion (7) for connecting the upper and lower leg portions (5, 6). With providing a stepped portion (8) in a center of the upper leg portion (5), a portion of the fastener element (2) on a side of the coupling head (4) is formed thick while a portion thereof on a side of the connecting portion (7) is formed thin. A coupling space (9) is provided between the upper and lower leg portions (5, 6). A protruded portion (10) protruded into the coupling space (9) is provided in a back of the stepped portion (8) of the upper leg portion (5). A slope portion (12) is formed such that the coupling space (9) is expanded from an inside of an upper portion of the coupling head (4) to a base portion (11) of the protruded portion (10). A core thread (28) is inserted between the upper and lower leg portions (5, 6) and sewed using a sewing yarn (15) of multi-thread chain stitches as fixing yarn (14), such that a side edge of the core thread (28) is protruded toward the coupling head (4). Upon coupling, the coupling head (4) is allowed to be inserted quickly along the slope portion (12) and an excessive insertion of a mating coupling element is prevented by the protruded portion (10) and core thread (28) so as to stabilize the coupling. Thus, the linear slide fastener enables a smooth and quick coupling operation.

A sliding clasp fastener (10) comprising a pair of support tapes (11, 12) carrying rows of coupling elements (13, 14) thereon and a slider (16) adapted to couple and uncouple the rows of elements. The elements (13, 14) are formed from a plastic monofilament into a continuous spiral or meander formation. The monofilament is provided with a multiplicity of indents (18) arranged to extend longitudinally thereof, the Indents being filled with a lubricative agent (19).

An apparatus (20) comprises a heated die wheel (22) having a circumferential groove (25), and a series of circumferentially spaced bending, punching and hammering units (28 - 30) disposed along the periphery of the die wheel (22) and having respective working heads (41a, 54, 71) projectable into the groove (25) to deform a filament (a) of thermoplastic material into a row of continuous zigzag coupling elements (g). Each of the working heads (41a, 54, 71) is movable in a direction parallel to the axis of the die wheel (22) in agreement with the lateral oscillation of the groove (25) when the die wheel (22) is rotated.
