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. |

A preform is made by casting a copolyester polymer elastomer into a block. While the block is solidifying, pressure is supplied to the central portion thereof. After a block is formed, it is annealed and a precompression force is applied thereto sufficient to compress the block to an extent greater than thirty percent of the original dimension of the block as measured parallel to the precompression force. In one embodiment a cushioning unit using the block is made by placing a pair of multi-apertured metal plates on opposite sides of the block with projections on the plates extending against the block and applying a second precompression force to the block and plates sufficient to cause the copolyester polymer elastomer to flow into the apertures in the plates and form a mechanical bond between the block and the plates. |
