Warp Tying and Beam Joining Technology
topic
Automatic warp tying machines join the ends of a new warp beam to the remnant warp threads still threaded through the weaving machine by tying knots or splices on each individual end in sequence across the full warp width at rates of 200 to 600 ends per minute, eliminating the need for manual drawing-in of each new warp end through heddles and reed after each beam change.
Role
Reduces the loom downtime between warp beams from the several hours required for manual drawing-in to 15 to 45 minutes for automatic tying when successive warps use the same thread path through heddles and reed, providing major productivity improvement for weaving mills producing large quantities of fabric in the same construction with frequent warp beam changes.
