Abstract

To improve the twisting of wire ends on a coil form having contact pins axially located with respect to a winding shaft, a swivel shaft is provided on each coil holder of a coiler tool. One end of the swivel shaft is in the form of a driving pin and the other in the shape of a fork. The fork shaped end of the swivel shaft is capable of engaging a driving pin located on a rotating drive shaft. The coil holder is in the form of a strap and tiltable. The wire ends are cut by a wire cutting device that is displaceable vertically with respect to a wire guide. The contact pins with the wire ends twisted on them in a parallel manner may serve simultaneously as plug-in pins for printed circuits.
