Abstract:
The invention relates to a metal pull−proof tube−armored cable, which is one kind of insulated wire, common cable or fiber wrapped around by the metal elastic pull−proof tube. The insulated wire or cable in roll is put into the armoring molding mainframe of the metal pull−proof tube−armored cable from the reel, and molded by the metal elastic pull−proof tube once, at last connected by the coiling section, in this way the cable is produced. The rotating speed and direction of the wire bracket, the cable bracket and the molded metal pull−proof tube−armored cable in the core axis of the armoring molding mainframe are same. The armoring molding mainframe for the production is improved from the prior metal elastic pull−proof tube machine, which core axis is empty instead of solid, and the minor diameter is no less than the diameter of the unarmoring cable.
