Apparatus for marking and scoring insulated wire or cable
The patent US12040104B1 describes an innovative apparatus designed for marking and scoring insulated wires or cables. Central to this apparatus is a housing that contains a wire path through which the insulated wire or cable travels. The system features an upper splined gear rod and a lower splined gear rod, which are offset along the wire path. An actuator, which can be a pneumatic double-cylinder linear actuator, is connected to the upper splined gear rod, allowing it to be raised or lowered. When the upper gear rod is lowered, it exerts pressure on the insulated wire or cable, effectively pressing it between the two gear rods. Additional components include a depth knob for adjusting the pressure applied to the wire and safety guards that extend the enclosure of the wire path.
Furthermore, the patent outlines a comprehensive manufacturing system for jacketed and insulated wires or cables. This system includes a payoff reel, a first extruder for applying insulation, and a tester that checks for defects in the insulated conductor. The marking and scoring apparatus is integrated into this system and is electronically connected to the tester, allowing it to respond to signals indicating when to mark or score the wire. The second extruder applies a jacketing material, such as a Nylon jacket, to the insulated conductor. A timing device is also included, which introduces a delay before sending a signal to the marking and scoring apparatus, with the delay determined by the distance between the tester and the apparatus, as well as the pulling speed of the insulated conductor. This integrated approach enhances the efficiency and accuracy of wire and cable manufacturing processes.
