Abstract:
1. A cable hanger production system in which a Z-winding spiral and an S-winding spiral are alternately and continuously formed along an axis via a switching part, comprising a housing having a cylindrical space in which a hanger wire is supplied from one end of the housing and the hanger wire is sent out from the other end thereof, and a plurality of spiral forming dice which are accommodated in the cylindrical space of the housing such that the spiral forming dice are adjacent to each other and configured to rotate independently from one another, wherein each of the spiral forming dice includes a bottom face forming a shape corresponding to a curvature of a spiral on a plane intersecting with the axis at right angles between an inner peripheral face of the housing and the bottom face, a Z-winding wall face forming a shape corresponding to a pitch of the Z-winding spiral which is inclined with respect to the plane, and an S-winding wall face forming a shape corresponding to a pitch of the S-winding spiral, the Z-winding wall face and the S-winding wall face intersect with each other at a central portion of the spiral forming die in a longitudinal direction thereof, and a region sandwiched between the Z-winding wall face and the S-winding wall face is constituted by the bottom face.
