ABSTRACT:
A weft yarn changer on a projectile loom has a pivoted changer member (1) for at least two yarn transfer elements (2) each in the form of a slide rod (2a) and a yarn gripper (21). Slide bars for the yarn transfer elements (2) are provided on the changer member (1) and are connected by at least one lightweight plastics holder to a tube effective as a drive shaft of the changer member or as a pivot spindle. The inventive weft yarn changer yields reduced actuation times.
