发明名称 Method of making elastomeric cushion pad
摘要 A method for making elastomeric cushion pads which can be used in off-the-road vehicles and in the draft gears of railroad cars. The method includes solidifying a molten mass of the elastomer under a pressure of at least 1000 psi to form an elongated slug of the elastomer which is then cut into a plurality of unfinished cushion pads which are then individually momentarily compressed to remove any permanent set or deformation of the pads which occurs when an uncompressed pad is initially compressed.
