ABSTRACT:
The invention relates to a machine for manufacturing cable forms of the kind used, for example, in relay sets. The machine is fully automatic insofar as the cables are formed at least to the stage where each wire is terminated with the insulation stripped from the ends, the ends being arranged such that when the manufactured cable form is placed on the relay set or other apparatus the wire ends are in the optimum position for connection to the terminals of the apparatus. The machine comprises a holding table slidable along a longitudinal frame and supporting a plurality of holding clutches simulating the configuration of terminals which, in use, the wires will be connected. The holding clutches firmly hold the ends of wires being used to make the cable form. A rotary indexing head is mounted above the table and is adapted to actuate any one of a plurality of different wires into an operating position wherein it may be introduced into a holding clutch. The head is slidable on the frame in a direction transverse of the sliding direction of the table and a numerical controller is programmed to provide positions for the table and the head to enable any wire to be introduced to any clutch and be routed along a predetermined path to any other clutch. Cutting and stripping blades move with the head and are arranged immediately below the wire in the active position. A returning mechanism in the form of spaced opposed discs is also arranged to move with the head and the discs are disposed immediately below the blades. The discs are adapted to grip a wire passing therebetween and move vertically between the blades and the table. Rotation of the discs through 180.degree. during said vertical movement causes the end of a routed wire to be inverted for introduction into a holding clutch. A checking circuit ensures that each wire is properly introduced into a holding clutch prior to a routing operation, with the insulation properly stripped from the end.
