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.

Marking device and method, and method for manufacturing fastener chain

A first member includes a first fixing portion on which a sheet edge is fixed, a holder continuous with an end of the first fixing portion, a first recess that is defined in the holder and has an opening in a continuous direction of the first fixing portion, and a support portion that is formed opposite the first fixing portion across the opening of the first recess of the holder. A second member includes a second fixing portion on which the other sheet edge is fixed, a held portion continuous with an end of the second fixing portion. When the held portion is inserted into the first recess, the support portion is brought into contact with a surface of the second fixing portion.

Sheet fastener

A slide fastener in which a fastener element has first and second leg portions continuously disposed at both ends of the coupling head is folded in half at its center, and the first leg portion is attached to a coupling element attaching portion of a fastener tape by a sewing thread. A vulnerable portion which is cut out into a V is formed on the bent end face of the coupling head.

Slide fastener

A slide fastener which withstands a predetermined lateral pulling force in a usual usage and is cloven when an excessive lateral pulling force is applied at the time of airbag inflation, wherein the slide fastener in which a plurality of attachment leg portions of coupling teeth, on each of which a coupling head formed to have a relatively large width and the attachment leg portions extending from the coupling head are formed, are attached on a coupling tooth attaching portion of each of a pair of fastener tapes on right and left with a predetermined pitch along a tape longitudinal direction is configured to satisfy a relationship 0.4&#x2267;(2&#xd7;H&#x2212;P)/P&#x2267;0.1 between a summit height H [mm] of the coupling head formed to have a relatively large width and a pitch P [mm].
