Abstract

PURPOSE: To reduce the manufacturing man-hour, and to manufacture the good quality tube, by automatically, simultaneously winding plural tubes keeping a constant distance between tubes.
CONSTITUTION: The angle θ, to be made by the axis M of the parent tube 1 against the axis T of the tube 2, is previously given to the tip side of the tube 2, and hereafter, the tube 2 is inserted into the hole of the spiral die 12. Next, the first tube 2 is fixed to the tube holder 6, the driving source 7 is put ON, the parent tube 1 is turned round by the angle equivalent to one turn/the number of tubes, and the driving source 7 is put off; synchronously with this work, the spiral die 12 is transferred as far as the specified distance in the axial direction. Hereby, the first tube 2 is wound around the parent tube 1. Hereafter, the work is similarly repeated as many times as the number of tubes. After the initial winding of the tube 2 is completed, the rotation of the parent tube 1 and the axial transfer of the spiral die 12 are given through one operation, keeping constant the angle θ made by the parent tube 1 against the tube 2, and the manufacture of the spiral tube is completed.
