Warp shed formation on shuttleless looms In the course of the downward movement of the upper towelling warp thread set, the upper main warp thread set, too, is moved downwards sufficiently to screen off the upper towelling warp thread set against the free end piece of a cut off weft thread length introduced into the shed. The downward movement of the upper towelling warp thread set is continued to a lower position fully open to the shed, and the upper main warp thread set is moved back into the upper position fully open to the shed before an immediately following cut off weft thread length in introduced into the shed. |
