Definitions

  • a bending head attached to a pivotal and reciprocable arm undergoes a sequence of movements to produce bending of the' overhanging ends" of the coils around the wire.
  • Two supporting plates 21 are fastened on both sides of the carriage 9 by means of screws (not shown), and mounted on the surface of the plates are seats 21a for receiving the edge wire 6.
  • the carriage 9 is provided with a large rectangular groove 22, as shown in FIG. 3, which extends centrally at the right edge 23.
  • a rib 24 of an auxiliary carriage 25 which is fixedly attached to the carriage 9 by means of screws (not shown).
  • a short guide 26 for a sliding member 27 is formed in groove 22 between the rib 24 and the bottom of groove 22.
  • the sliding member 27 has an upper fork end 28 attached to the lower end 30 of a swivel arm 31 by means of a pivot 29.
  • the portion 8 is bent to the form 8d as shown in FIG. 19, this occurring shortly before the end of, the upward movement of the arm 31.
  • a protruding edge 61 of the arm 31 slides along an upper, inwardly inclined sliding surface 62 of the stop 45, whereby the arm- 31 is subject to a small tilting movement in the counterclockwise direction, to bend the portion 8 over the edge wire 6 and complete the operation as seen at Se in FIG.
