There is provided a slider for a slide fastener. The slider includes a slider body, an elastic body and a pull tab. The pull tab includes a shaft, a pull tab main body and a cam. The cam is configured to elastically deform the elastic body when the pull tab is laid down. The slider body includes an upper blade and a pair of pull tab attaching posts. The upper blade includes a recess portion and a crimping portion. The recess portion includes a pair of lateral recess portions and a center recess portion. The crimping portion protrudes from at least one of the lateral recess portions at a protruding location located at a center side relative to both front and rear ends of the center recess portion.


This slide fastener (1) is characterized in that the first and second main surfaces of the main body (21a, 51 a) of the engaging head (21, 51) of the fastener elements (20, 50) are flat surfaces that are orthogonal to the longitudinal tape direction and the pair of legs (23, 53) of the fastener element (20, 50) curve in a diagonal direction or extend at a slant with respect to the first and second main surfaces of the main body of the head (21a, 51 a). As a result, this slide fastener (1) has a different external appearance from previous slide fasteners and is able to stably achieve strength with respect to transverse pulling and strength with respect to thrusts that are equivalent to or greater than previous slide fasteners.

A cloth evaluation apparatus can grasp the piercing property and the cutting property with a cloth in advance. The cloth evaluation apparatus (1) comprising: a measuring member (21, 71, 81) having, on its distal side, a measuring part (22) to pass through a cloth (c, d); a cloth/measuring part moving means (30, 40) for moving the cloth (c, d) or the measuring member (21, 71) so that the measuring part (22) passes through the cloth (c, d); a cloth supporting means (23, 23, 31) for supporting the cloth (c, d) at around a passing-through point, in the cloth (c, d), of the measuring part (22) from both sides of the cloth (c, d) when the measuring part (22) passes through the cloth (c, d); and a load detecting means (25) for detecting a load being applied to the measuring member (21, 71) while the measuring part (22) passes through the cloth (c, d). The measuring part (22) includes a piercing force measuring portion (22A, 72A) whose outer diameter gradually decreases toward its acute tip (22A) and, after the tip (22A) sticks the cloth (c, d), the piercing force measuring portion (22A, 72A) can pass through the cloth (c, d) while expanding a grain of the cloth (c, d). The measuring part (22) also includes a cutting force measuring portion (22B, 72B) adjacent proximally to the piercing force measuring portion (22A, 72A), the cutting force measuring portion (22B, 72B) having a shear face (22Bb) which can push a part of the cloth (c, d) in the passing direction to separate the part from the cloth (c, d) as the measuring part (22) passes through the cloth (c, d).

Provided is a sewn product in which a tape edge of a fastener tape and a material edge of a main material that is thicker than the fastener tape are stitched together in an abutted state, wherein the tape edge and the material edge are stitched together with one bobbin thread and two needle threads, the two needle threads being interlocked with the one bobbin thread to form a plurality of rows of zigzag stitched seams. In addition, the fastener tape and the main material are respectively fed with feed dogs that are set at different feed rates, while the first and second materials are pressed at an equal pressure.


A fastening tape having flexibility in a longitudinal direction of the fastening tape. The fastening tape includes a plurality of fasteners, a support, and magnetic material positioned on the support. The support defines a plurality of plateaus and a plurality of valleys. The magnetic material is positioned on at least a portion of one of the plurality of plateaus or the plurality of valleys of the support such that a height of the magnetic material varies in the longitudinal direction. Because the height of the magnetic material varies, the fastening tape is more flexible in the longitudinal direction. In some cases, the fastening tape is also flexible in the lateral direction.


A fastening tape has flexibility in a lateral (width) direction of the fastening tape. The fastening tape includes a body, a plurality of fasteners, and a plurality of transverse walls. The plurality of fasteners and the plurality of transverse walls extend in an upward direction from a top surface of the body. The plurality of fasteners are arranged in rows extending in the lateral direction. Each transverse wall includes a transverse wall width, and at least some of the plurality of transverse walls are arranged in the rows of the plurality of fasteners and connect fasteners in the rows fasteners. The fastening tape includes at least one slit within or adjacent at least one of the transverse walls, which increases flexibility in the lateral direction of the fastening tape.

A surface fastener member includes left and right longitudinal protective wall sections and front and rear lateral protective wall sections. Each of the lateral protective wall sections includes an outer first lateral wall section and an inner second lateral wall section. The first lateral wall section is continuously placed between the left and right longitudinal protective wall sections at a predetermined height. The second lateral wall section includes a plurality of divided lateral wall bodies which are intermittently placed along a width direction, and a plurality of second engagement elements. The distance is set smaller than a mounting pitch of the first engagement elements in the longitudinal direction of the surface fastener member. According to this, when the molded surface fastener is integrally molded on a cushion body, it is possible to prevent resin material from entering an engagement element region of the surface fastener member.
