Forming layered coil windings on spool - moving guide for wire axially at controlled rate with axial reversal of feed direction produced by mechanism.

摘要

A coil winding machine receives wire (1) from a main spool over a tensioning pulley (3) and guide pulley (2) to a guide leading to the coil winding spool (6). The guide pulley and tensioning pulley are mounted on a frame (7) that moves axially on rollers to form layers of windings on the main coil winding spool. The motion occurs with a reciprocating action with an automatic feed direction reversal. The automatic reversal takes place when the wire guide (5) contacts the sides of the spool flange. This causes a pivoting action to take place. ADVANTAGE - Accurate layering of coil windings on spool independently of wire dia. and mfg. tolerances.
