Zusammenfassung: | PROBLEM TO BE SOLVED: To prevent abrasion of a movable knife, and to shorten a projection length of a pressing unit of a needle bar while making available when a gap between the needle bar and the movable knife is large.SOLUTION: A sequin feeding device comprises: a movable knife 21; a pressed member 25 provided changeably at a position spacing to a needle bar 80 side from the movable knife 21, and pushed down by a pressing unit 82 of the needle bar 80 in drop of the needle bar 80; and a power transmission mechanism 30 driving the movable knife 21 by transferring the force that the pressed member 25 caught from the pressing unit 82 to the movable knife 21. Sequin S is separated from a tip of a sequin tape T by driving the movable knife 21.
【課題】可動メスの摩耗を防止する。それに加え、針棒と可動メスとの間の間隔が広い場合にも対応可能にしつつも針棒の押下部の突出長を短くする。【解決手段】可動メス21と、可動メス21から針棒80側に離間する位置に交換可能に設けられて針棒80の降下時に針棒80の押下部82に押し下げられる被押下部材25と、被押下部材25が押下部82から受けた力を可動メス21に伝達することで可動メス21を駆動する動力伝達機構30とを設ける。そして、該可動メス21を駆動することでシークインテープTの先端部からシークインSを切り離す。【選択図】図3 |
