Claims (1)

[Claims for Utility Model Registration] A winding drum that is rotatable around one axis, protrudes like a beak in a direction perpendicular to the axis, and has a hollow hole for insertion of a hook in the same orthogonal direction; a hook located at the rear of the winding drum and provided at its tip so that it can move forward and backward so that the hook protrudes from the rear of the winding drum through the insertion passage to the front of the winding drum; A supply thread through hole located at the tip thereof rotates around the longitudinal axis of the winding drum, and between the vicinity of the winding drum and the vicinity of the tip of the hook in a state where the hook protrudes from the winding drum. a winding rod that is provided so as to be able to turn and move back and forth so as to reciprocate; a winding rod that is located at the rear of the winding drum, moves forward across the forward and backward path of the hook, and is located on the opposite side of the forward and backward path of the hook; a chuck mechanism that can be opened and closed and moved back and forth by pinching the end of the spool remaining yarn to be pulled back; a disengagement mechanism that disengages the supply yarn; a holding mechanism that is located below the winding drum and holds the end of the supply yarn; and a holding mechanism that constantly applies tension to the supply yarn and when tying a tension mechanism capable of pulling back the supply yarn; a fixing mechanism that fixes the spool or a shuttle containing the spool; The process of winding the supply yarn on the winding drum by turning it around the longitudinal axis once or several times, and the process of rotating the winding drum around which the supply yarn is wound, are performed once or several times, and then the hook is turned around the winding drum. The hook is advanced from the rear of the winding drum until it passes through the insertion path and projects to the front of the winding drum, and then the winding rod is rotated at a slightly retreated position to feed the supply yarn to the tip of the winding rod. wrapping,
The rear hook is moved backward until its hook reaches the rear of the winding drum, and the chuck is moved forward across the path of advancement and retreat of the hook to remove the remains of the spool located on the opposite side of the path of advancement and retreat of the hook. Pinch the end of the thread, move it back again, insert and hold the remaining thread between the supply threads pulled back by the hooking claw, actuate the disengagement mechanism, and release the thread by the hooking claw. automatic control means for knotting by automatically sequentially performing the above steps of disengaging the thread and pulling back the supplied thread by operating a tension mechanism; Nodulation device.
