ABSTRACT:
This insulation applicator applies electrical insulation to a thin conductive strap that is attached to and extends transversely of wire being wound into a coil. The applicator comprises two applicator segments between which is a feed passage through which two strips of insulation are fed. The segments are moved transversely of the wire from a first position at one side of the wire to a second position at the other side, thus introducing the strap into the feed passage. Holding means releasably holds the strips respectively to the segments while the strips extend through the feed passage, thus carrying the strips with the segments and holding apart the forward ends of the strips during the above-described transverse movement of the segments. Means on the segments acts when the insulating strips have been so moved to force the strips together about the strap and effect bonding between the strips. Additional means then acts to release the strips from the segments, to return the segments to their initial position, and to cut off the strips adjacent said first position of the segments.
