Slide fastener

A first stop member includes a first base and a first insert that is positioned between the first base and a first fastener element and is inserted into the slider via a rear mouth of a slider. A second stop member includes a second base and a second insert that is positioned between the second base and a second fastener element and is inserted into the slider via a second slit of the slider. The second insert moves toward the second slit of the slider in accordance with at least one or respective rotations of the first and second bases. A rotational axis with respect to the at least one or respective rotations of the first and second bases is positioned between the first tape region and the second tape region.

Slide fastener

A slide fastener includes a resin sheet that joins tapes on one surface among both surfaces of the tapes in a thickness direction, and that extends from a stop on a side opposite to element rows and is integral with the stop. The stop includes recesses on a boundary portion with the sheet of left and right side portions that respectively correspond to the tapes, and includes a recess region in a surface of the stop that is a region whose range in a left-right direction is defined by leftmost and rightmost ones of the recesses. A surface of the sheet includes a flat portion that is a region extending from the recess region toward the side opposite to the element rows.

A marking device performs a marking process onto a long object. The marking device includes a driving source and a marking unit that performs a circular motion in accordance with a driving force supplied from the driving source. While the long object is being transferred, marks are applied onto the long object in accordance with the circular motion of the marking unit. An extent of interference by the marking unit to the transfer of the long object is reduced, thus facilitating higher speed transfer of the long object.

Fastener Chain and Slide Fastener
20220192325 · 2022-06-23 ·

A coil-shaped fastener element is sewn to a fastener tape without using a core string. An upper leg portion of the fastener element has a first upper surface continued from a connecting portion and contacting a sewing thread, and a second upper surface extending and sloping upward from the first upper surface via a bent portion. A height dimension between a top end surface and the bent portion of the upper leg portion is 20% or larger of a height dimension of the fastener element. The upper leg portion has a first lower surface which is sloped to be apart from the fastener tape toward a coupling head portion, and the upper leg portion has an element contacting portion in an area of the first lower surface. Thereby, cost reduction of the slide fastener can be attained, and the fastener element can be prevented from passing through the sewing thread and exiting.

Fastener stringer
11350708 · 2022-06-07 · ·

A fastener stringer has a fastener tape provided with a tape main body portion and an element attaching portion and a plurality of fastener elements fixed by weaving to the element attaching portion of the fastener tape at the same time of weaving of the fastener tape, and is provided with a weaving structure with one pitch per one-rotation. A weft yarn of the fastener tape has a fineness larger than that of at least a part of a warp yarns disposed in the tape main body portion. Thereby, the productivity of the fastener stringer can be increased to reduce the cost. Further, the density of the weft yarn in the fastener tape can be increased, and the fastener tape can be less likely to be misaligned.
