A WINDING MACHINE COMPRISING A WIRE CATCHING MEMBER FOR THE PROVISION OF TAPPINGS

摘要

For the automatic provision of tappings by winding annular cores, a winding machine comprising an annular wire guide member (1) rotatable about its own axis, the path of movement of which encircles the cross-section of the core, is provided with a hook-shaped wire catching member (10) which by pivotal movement about an axis (11) parallel to the winding plane (8) against a first bias force may be carried from a rest position (10a) outside the winding plane (8) to a catching position (10b) engaging the winding plane (8) to receive a loop of the winding wire (9). The wire catching member (10) is influenced by a second, oppositely directed bias force (37) against which, after having caught a wire loop in the catching position (10b) it is carried to a retaining position (10c) between the rest and catching positions (10a, 10b) and outside the winding plane (8) due to the tightening of the wire (9). The activation force for the movement of the wire catching member (10) is maintained in a prescribed ligation period after occupation of the retaining position (10c).
