| 20080257444 | CABLE HANGER PRODUCTION SYSTEM AND PRODUCTION METHOD - There is produced a cable hanger in which a Z-winding spiral and an S-winding spiral are alternately and continuously formed along an axis via a switching part using a hanger wire. A hanger wire is supplied from one end of a housing and sent out from the other end thereof. At least five spiral forming dice are accommodated in a cylindrical space of the housing such that the spiral forming dice are adjacent to each other and can rotate independently from one another. Each of second and subsequent spiral forming dice as counted from the hanger wire supplying end of the housing includes a bottom face forming a shape corresponding to a curvature of the spiral on a plane intersecting with the axis at right angles between inner peripheral face of the housing and the bottom face, and the bottom face gradually becoming narrower from both sides of the spiral forming die in its longitudinal direction toward a central portion thereof, a Z-winding wall face forming a shape corresponding to a pitch of the Z-winding spiral and an S-winding wall face forming a shape corresponding to a pitch of the S-winding spiral, which are inclined with respect to the plane and the axis. The Z-winding wall face and the S-winding wall face intersect with each other at a central intersection of the spiral forming die in the longitudinal direction thereof, and extend along a side edge of the bottom face. The first spiral forming die as counted from the hanger wire supplying end of the housing has a latter half thereof in its longitudinal direction, the latter half includes the bottom face, the Z-winding wall face and the S-winding wall face in the same as those of latter halves of the second and subsequent spiral forming dice in the longitudinal direction. The first spiral forming die also has a first half including an introducing portion extending along the axis, the introducing portion is connected to a front portion of the intersection in the bottom face of the latter half in the longitudinal direction, and a front end of the introducing portion includes a hanger wire introducing inlet. | 10-23-2008 |
