ABSTRACT:
Apparatus for winding a pair of elongated bodies, e.g. wires, on a mandrel in which a pair of bobbins and a U-shaped cage are rotatably mounted on a fixed shaft extending horizontally from a support slidably mounted on a pair of rails supported by a base. The arms of the cage extend on opposite sides of the peripheries of the bobbins and parallel to the axis of rotation of the bobbins, and the cage is motor driven. A mandrel with its axis aligned with the axis of the bobbins is supported by a cylindrical body rotatable with respect to the mandrel and a separable threaded connection with a rotatable sleeve in the shaft, and the body carries guide arms engageable with pins on the arms of the cage. A crank arm connected to the rotatable sleeve permits disengagement of the mandrel from the sleeve. The base also carries pneumatically operable arms which can be moved into and out of engagement with the cylindrical body and the mandrel to hold the body and the mandrel as the support is slid along the rails away from the mandrel to permit empty bobbins to be replaced.
