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). The slide rod (2a) is made of plastic and is longer radially than tangentially in the pivoting direction relative to the pivoting axis. A duct (24) oriented in the sliding direction forms a cavity which is particularly suitable as a yarn guide. The inventive yarn changer has short actuation times.
