ABSTRACT:
A mechanism for presenting weft threads on rapier weaving machines includes a cam mechanism, cam follower devices, armatures connected to the cam follower devices, and thread presentation arms. The cam mechanism and cam follower devices impart reciprocating movements to the armatures such that, alternately, for each successive weaving cycle, the armature connected to one of the cam follower devices cause the movement of one of the thread presentation arms into a presented position, while the armatures connected to the other cam follower device move back to a rest position a thread presentation arm which has just been presented.
