Warp Tying and Drawing-In Automation
topic
Automated warp tying machines use pattern-reading systems to identify the repeat structure of the existing warp, then tie the new warp ends to the corresponding old ends using mechanical knotters at speeds of 80 to 300 ends per minute, while automated drawing-in machines use robotic handling to thread individual warp ends through heddles and reed dents according to the weave design programme, replacing the skilled manual drawing-in operation for new warps.
Role
Automates two of the most skill-dependent and labour-intensive warp preparation operations in weaving, with warp tying machines reducing the warp change time from hours to minutes for repeat warps and drawing-in machines eliminating the skilled manual threading operation for new fabric constructions, with automation of these operations significantly reducing the technical staffing requirements for weaving room warp preparation that limits the flexibility and responsiveness of conventional weaving operations.
