Warp Pulling Through Heddles and Reed
topic
After tying, the new warp is pulled through the existing heddle and reed threading by advancing the fabric take-up system while the old warp beam unwinds, with pulling speed limited by the tension required to move the knots through heddle eyes and reed dents without breaking the tying knots or causing heddle accumulation at restriction points, and with slow careful advancement of the first few metres being required to identify and correct untied or misspun ends before full-speed pulling begins.
Role
Transfers the new warp threading from tied ends at the back of the loom to weaving position at the front by mechanically advancing the warp through the existing threading, with the pulling operation being the critical test of tying knot quality and warp alignment accuracy that reveals tying errors as individual ends that stop advancing at restriction points requiring manual correction before resuming pulling.
