Title: Combination slot liner and retainer for dynamoelectric machine conductor bars

Abstract: A U-shaped slot liner is provided with a porous spongy longitudinal rib on each leg. The ribs mate with complementary grooves in the dynamoelectric machine coil slot, side walls and the conductor bar side walls. When the assembled machine element is impregnated by a thermosetting liquid, the ribs absorb the liquid and become hard when heated.
