Warp Tying Machine Technology
topic
Automatic warp tying machines clamp onto the weaving machine frame with the loom warp threads and the new beam warp threads positioned in parallel planes, using an automatic knotting head that traverses across the warp width tying each pair of old and new warp ends together with a weaver knot at rates of 400 to 600 ends per minute for warp widths up to 4 metres with end counts up to 10000 total ends.
Role
Enables rapid warp beam change without full drawing-in by tying new warp ends to the existing threaded warp remnant, with tying time of 15 to 45 minutes for a full-width warp replacing the 8 to 16 hours required for manual drawing-in and providing major loom productivity improvement for styles producing many beam changes per month in the same fabric construction.
