ABSTRACT:
Packing spacer sheets are automatically fed one at a time to a pick-up station from a stack, with selected sheets arranged to arrive in inverted condition so that all packing sheets are properly oriented into packing position. Sheets can be pulled from stack by a transfer carrier having gripping jaws with teeth that dig into rib structures on sheet and jaws can open to engage other portions of sheet and thus hold the sheet to assure all teeth are pulled out of sheet. Stack can be a horizontal nesting of generally vertically disposed sheets carried by narrow spaced belts stepped along on a low friction surface with fixed retainer to stop forward face of stack and permit front sheet to be pulled off.
