720,685. Coiling. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 10, 1953 [March 29, 1952], No. 3675/53. Class 83 (4). A machine for wind. ing filament wire about a mandrel is characterized in that a heated pin is disposed in contact with the wire in the vicinity of the mandrel so that the wire, as it is wound, is heated by conduction and radiation of heat from said pin. Wire 41, from a spool 40 carried on a hollow shaft 39 of a coiling head 10 rotating in a pedestal 14, passes over guide rolls 52, 54 on a yoke 32 extending from a flywheel 22 of the coiling head, and between a heated pin 72 and a die 44, spring-urged thereagainst, to a non- rotatable mandrel 50 laterally reciprocable through the hollow shaft 39. The pin 72 is carried by a support 67 pivoted to extensions 68, 70, Fig. 2, of a nose 48 of the ceiling head and adjustably secured by a screw 65 to said nose. The pin 72 extends between a support member 76 on the support 67 and a support member 74 on, but insulated from, the support 67. The support member 74 is connected electrically to a brush 58, through a slip ring 20, lead 62, terminal post 60 and lead 78, the other support member being electrically connected to a brush 56 through a slip ring 16, a hollow shaft 12, flywheel 22, yoke 32 and support 67.
