The pivot lever 16 is pulled against the gripper support 8 either by means of a secondary extension of the pivot lever 16a or by means of a spring. In the former case, both the pivot lever 16 and its secondary extension 16a carry rotatable sensing rollers 18, 18a. At the ends of the swivel levers 16, hook members 19, 20 projecting at right angles to them are provided, which lead through slots in the gripper support 8.

Abstract

Afin de nouer le lien (4) enroulé par un organe de guidage tournant (1) autour d'une marchandise (2), on prévoit une unité de nouage (6) et un support de crochets (8) avec deux crochets (12, 13). Un dispositif d'amenée (7) est en liaison active avec l'unité de nouage (6) et amène à celle-ci une boucle de lien (39). L'installation de nouage comporte un doigt (27) qui pousse la partie du lien (4) sortant de l'organe de guidage (1) vers les deux crochets (12, 13). Les derniers retiennent temporairement le lien (4) de manière à permettre de nouer le bout avant (40) de la boucle (39) à l'extrémité du lien (38). Le second crochet (13) est doté d'un couteau (23) qui, lors de l'ouverture, tranche le bout avant (40), puis retient le lien amené (4).
