を形成するとともに該天秤によつて形成される軌
跡の適所に該軌跡を挾むガイドを配置し、天秤の
往動時に係合聞が両ガイドに通された糸に係合し
てそのまま該糸を屈折した状態で牽引する一方、
復動時には糸への牽引が解除される天秤装置にお
いて、復動時に糸に係合する上記係合部と反対側
の天秤部分をカム状の案内部として形成し、該部
に係合した糸がなおも復動をつづける天秤の動き
に伴い、案内部を滑つて押出されながら天秤端に
達し、該端をのり越えるようにした天秤装置。 A thread-engaging part is formed on a thread take-up reciprocating in conjunction with the upper shaft, and a guide is placed at an appropriate position on the trajectory formed by the thread take-up, and is engaged when the thread take-up moves forward. While the two guides engage the thread passed through both guides and pull the thread in a bent state,
In a thread take-up device in which traction on the thread is released during a backward movement, a thread take-up part on the opposite side of the engaging part that engages with the thread during a return movement is formed as a cam-shaped guide part, and the thread engaged with the part is formed as a cam-shaped guide part. As the balance continues to make a backward movement, the balance slides along the guide part, reaches the end of the balance, and climbs over the end.
