Abstract

The entry and exit rapiers of a weft inserting mechanism in a vertical weaving machine have guide means for contacting the sheets of warp strands which form a shed during the weaving of fabric so that lateral movement of the rapiers is inhibited while they are traveling weft-wise between the sheets. One rapier also has an associated clip guide for engaging the other rapier to prevent substantial vertical divergence of the rapiers as they come together so as to facilitate transfer of the weft yarn from the entry rapier to the exit rapier.
