Abstract : Certain unusual developments that have contributed to the success of making this machine a practical and efficient tool for the direct extrusion of aluminum sheath on insulated electrical cables have been stressed. The most interesting developments from the cable users' and manufacturers' point of view are: (1) The efficient cooling system to protect the cable insulation while it is in the die block. This feature permits the extrusion at relatively high temperature and low pressures. (2) The 'ratchet spanner' arrangement for the control of sheath wall thickness. (3) The 'tapered-heating' and progressive 'upsetting' of billets displacing air from the containers and preventing formation of blisters in the sheath. (4) The synchronization and equalization control of the advance of the rams during the extrusion of the aluminum sheath. (Author)
