Definitions

  • the invention relates to a coil holder shaft.
  • the invention which is the subject of this patent solves the problem of balancing by making the rotation of each spool independent of the rotation of the others.
  • the plastic strips can run on the inner ring of the wreath; this means that the speed of rotation of the ring and consequently of the coil firmly connected to it decreases and the winding of this coil adjusts to that of the others.
  • the friction of the plastic strips on the rim can be adjusted by increasing or decreasing the pressure in the air bags.
  • Figure 1 shows a view of the shaft with the outer surface of the shaft (A) and one of the ledges (B) visible;
  • Fig. 2 shows a cross section of the shaft (A) with the strips (B) and the expansion hose (C);
  • Fig. 3 shows a cross-section of the ring, in which the inner eccentric ring is designated by (D), this causes the movement of the balls (E) which raise the elements (F) through the action of the strips (B), which in turn act on the core of the coil to be wound, denoted by (D);
  • Fig. 4 shows a view of a ring that is attached to the shaft and next to which there is a friction ring (G).
