<p>Apparatus is disclosed for feeding rectangular metal sheets from a supply to a cupping press in which can body blanks are cut and drawn from the metal sheets. The apparatus includes a table providing a flat conveying surface, and three sheet feeding mechanisms are provided at locations along the table between the opposite ends thereof. A sheet to be transferred is deposited on one end of the table and is transferred therefrom to a second position by an endless chain and feed finger arrangement. At the second position, the trailing edge of the sheet is engaged by a reciprocating feed finger arrangement to advance the sheet one step to a third position on the table in which the sheet is accurately spaced longitudinally relative to a reference point in the press. In the third position, the sheet is also laterally positioned with respect to the reference point, and the trailing edge of the sheet is engaged by the first of a series of reciprocating feed fingers which are operable to intermittently advance the sheet through the press. Following the last blanking operation, the leading edge of the sheet is engaged between a pair of discharge rollers by which the remaining scrap is removed from the press.</p> |
