ABSTRACT:
Apparatus for handling a plurality of clad elements of a predetermined configuration formed from a sheet consisting of a layer of an elastomeric material bonded to a layer of inert material and deposited in openings of a die corresponding in number and arrangement to cavities of a mold. The apparatus has a transfer mechanism with a plurality of rods having a pickup face with at least one fluid port. The rods correspond in number and array to the die openings and mold cavities. The fluid port is connected to a source of vacuum to retain a clad element on the pickup face when it engages the element in the die openings and to an air pressure source to discharge the clad element in the cavity of the mold. The apparatus further includes a reciprocating punch having a plurality of punch rods for forming the clad elements from the sheet material and depositing them in the openings of the die. The said die and mold are positioned adjacent one another. The mechanism is adapted for translating movement between a first position overlying the die with the punch rods aligned with the die openings and a second position overlying the mold with the pickup rods aligned with the mold cavities.
