Automatic Drawing-In Machines
topic
Automatic drawing-in machines use robotic gripper systems to separate individual warp ends from the lease section, hook each end in sequence through the correct heddle eye according to a programmed threading repeat, and insert the threaded heddle into the correct shaft position at drawing-in rates of 100 to 200 ends per minute across warp widths up to 4 metres for weave repeats of up to 32 shafts.
Role
Reduces the labour requirement and threading error rate of warp drawing-in compared to manual threading by workers, enabling 24-hour drawing-in machine operation that prepares warp beams for weaving without the skilled labour constraint of manual drawing-in that is increasingly scarce and expensive in modern textile markets.
