  • the fixed clamping part is designed as a housing with a hook-shaped clamping section for receiving a weft thread and the movable clamping part as a clamping lever which, under the action of a coil spring, can be pivoted about an axis running transversely to the longitudinal direction of the housing in order to clamp the weft thread.
  • the use of the coil spring proves to be disadvantageous because space and means for holding and / or guiding the same have to be provided for this purpose.

Abstract

La pince comprend un boîtier (1), une pièce de serrage (5) dotée d'une section de serrage (12) en forme de crochet destinée à recevoir un fil de trame et une unité de serrage (6) dotée d'une languette (22), d'une barre de torsion (23) et d'une patte (7). La languette (22) est pivotante, coopère avec la section de serrage (12) et est soumise à l'action de la barre de torsion (23) pour serrer le fil de trame. La force de serrage est fournie par la barre de torsion (23) et l'effet de serrage est supprimé par la patte (7). La pince a l'avantage d'être composée d'un minimum de pièces et d'avoir un poids très faible.
