  • Methods for forming arcuate insulation sheets for dynamoelectric machines
    Patent number: 5738815
    Abstract: The apparatus includes a stand for mounting a mandrel against rotation and a winding assembly for disposition within the mandrel. The mandrel has a slot for receiving a flat sheet through a side wall of the mandrel. A clamping mechanism on the winding assembly clamps the leading edge to the winding assembly within the mandrel. By winding the assembly, the flat sheet is drawn into the mandrel and formed into an arcuate configuration. The mandrel with curved sheet is removed from the stand and disposed in an oven for setting the plastic material in the curved configuration whereby the flat sheet is preformed into a radius approximating the radius of the rotational part about which the insulation will be installed.
