Abstract: A cable hanger which can alternately and continuously form a Z-winding spiral and an S-winding spiral using a hanger wire. A hanger wire is supplied from one end of a housing and sent out from the other end thereof. A plurality of spiral forming dice are accommodated in a cylindrical space in the housing. Each spiral forming die includes a bottom face forming a shape corresponding to a curvature of a spiral on a plane intersecting with an 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 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 S-and Z-winding wall faces intersect each other at a central portion of the spiral forming die.

Abstract: A system and method for producing a cable hanger formed by alternately and continuously forming the Z-winding spiral and the S-winding spiral using the hanger wire. The system and method involve the use of at least five spiral forming dice 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.

Abstract: A method and apparatus including an easily installed spiral support useful laying a cable. The spiral support is composed of a counterclockwise spiral portion and a clockwise spiral portion, both of which are connected to each other with a reverse portion therebetween. The spiral support is installed on a messenger wire in such a way that the reverse portion is fitted on the messenger wire; the spiral support is rotated counterclockwise or clockwise; and these steps are repeated.

Abstract: 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.
