Abstract
Method for forming a laminate and a product formed thereof. A thin layer of oil is applied to a facing surface of at least one of a plurality of adjacent laminations. The laminations are passed between a pair of rollers which apply sufficient pressure to remove excess oil between the facing surfaces. The air between the facing surfaces is displaced and the remaining oil forms a seal to prevent reentry of the air. The laminate is tightly held together to permit handling or fabrication without delamination.
