ABSTRACT:
A coil winding machine for winding a bar type conductor into a coil. The conductor is withdrawn from a reel by a feeding mechanism and passes through a straightening mechanism which also positions the conductor in both a horizontal plane of reference and a vertical plane of reference which is maintained while the conductor is progressing through the machine. An encoder measures the length of the conductor as it passes by and when the required length is measured the cut-off mechanism is actuated to cut the conductor. The conductor moves a taping assembly that applies insulating tape to both edges of the conductor for insulating adjacent turns from each other in the completed coil. A bending mechanism then bends the leading end of the conductor at an angle to the length of the conductor to form a terminal for the coil. This bent end is then clamped to the mandrel. As the mandrel is rotated it is also moved axially to wind the conductor about it in a helical path to form the coil. When the trailing end of the conductor arrives at the bending mechanism it is also bent to form the second terminal of the coil. The mandrel is expandable radially to receive the conductor and wind the coil and is retractable radially to release the completed coil for removal. The mandrel is also split radially so that the two portions can be separated for removal of the completed coil.
