Abstract
A method for cutting a coil conductor in which a halted conductor wire 2 to be formed into a coil is served by cutting edges 5A, 5B, while simultaneously advancing a cutting edges downstream in the feed direction of the wire. Thus, a pushing back force against the conductor wire and its attendant deformation is prevented when cutting it, whereby the dimensions of the conductor wire are stabilized.
Claims5
A method for cutting a coil conductor, comprising the ordered steps of:
- a) linearly infeeding a coil conductor by a predetermined amount,
- b) halting the coil conductor;
- c) feeding linearly reciprocable cutting edges disposed on opposite sides of the coil conductor in a downstream direction, and
- d) simultaneously with step c), moving the cutting edges inwardly, towards each other, to cut the halted coil conductor, thereby preventing the cutting edges from push-camming an end of the coil conductor being severed in an upstream direction.

A method for cutting a coil conductor, comprising the ordered steps of:
- a) linearly infeeding a predetermined length of a coil conductor to be cut,
- b) halting said coil conductor,
- c) advancing a pair of linearly reciprocable cutting edges disposed on opposite sides of the coil conductor in a direction downstream of said infed coil conductor and parallel thereto, and
- d) simultaneously with step c) and in synchronism therewith, moving the cutting edges inwardly, towards each other, to cut the halted coil conductor, thereby preventing the cutting edges from push-camming an end of the coil conductor being cut in an upstream direction.
