ABSTRACT:
The present invention relates to a method and apparatus for making an elastomeric spring assembly comprised of first and second plates joined to opposite sides of an annular elastomeric spring member. The preferred method of the present invention includes the steps of arranging the first and second plates in spaced and aligned relation relative to each other; laying a preformed annular elastomeric spring member between the spaced plates; positioning the spring member at a predetermined location relative to the plates as with a powered apparatus movable intermediate the plates between a first position whereat the apparatus engages and positions the spring member relative to the plates and a second position whereat the apparatus is removed from between the plates; and, compressing the spring member between the plates with a force sufficient to establish a cold-formed interlock between the plates and the spring member. The present invention further discloses a press apparatus capable of making an elastomeric spring assembly according to the method of the present invention.
