Abstract
A bearing slipper for supporting a component of a matchplate mold-making machine for back and forth sliding along an elongated rail. The slipper comprises a rigid mounting block having one face covered wholly or partially by pad means made of tough anti-friction material. Resiliently yieldable elastomeric strips are compressed in grooves at opposite end portions of the block and urge the end portions of the pad means outwardly so as to form protruding fins which wipe sand from the rail as the slipper moves back and forth along the rail.
