ABSTRACT:
The bulk volume of large numbers of loose, separated, multiply bent, irregularly shaped scrap sheet metal is temporarily reduced, for transportation and storage of the metal for recycling purposes, by compressing the metal into temporary, compacted wafers formed of successively compacted layers. The apparatus includes a load chamber which is axially aligned with a compression chamber and a reciprocating ram which passes through the chambers towards an anvil plate which closes the discharge end of the compression chamber. A pre-determined quantity of loose pieces is placed within the load chamber. The reciprocating ram compresses the pieces of that batch into a thin layer. Successive batches are compressed into overlapping layers which are temporarily bound together, face-to-face, to form a unitary wafer, by temporarily bending and intertwining the peripheral edges of the layers. The layers are subsequently separated for recycling by depositing into a melt furnace.
