ABSTRACT:
An apparatus is provided for directing at least two flows of synthetic material from an extruder to an extruder cross-head for coating a conductor wire with two layers of insulating material and to readily reverse the colors of the layers. The apparatus includes at least two separate tubes which communicate with an extruder outlet for directing synthetic material from the extruder outlet to the respective tube. The tubes communicate at their outlet ends with respective inlet openings of the extruder head. A rotator block is arranged to selectively and quickly reverse the positions of the outlet openings of the tubes with respect to the inlet openings of the extruder head such that after reversal, the outlet opening of each tube communicates with the other inlet opening of the cross-head. Thus, the capability to reverse the flows of insulating material is provided thereby making it possible to reverse the colors of the inner and outer layers of insulating material on the conductor wire.
