Abstract
The skeleton discharge mechanism receives the leading edge portion of scrap skeleton sheets one at a time from a press at an entrance portion of a support surface exactly positioned by the press relative to a pick-up station and transversely spaced pairs of engagement members move partially upwardly through the support surface on a timed basis to engage the sheet leading edge through press formed part openings. The engagement members are secured to chains constantly moving over sets of sprockets along closed paths and after engaging the sheet leading edge move longitudinally along the support surface to a surface exit portion pulling or dragging the sheet through the mechanism. At the surface exit portion, the engagement members move downwardly in their closed paths disengaging the sheet which continues on to discharge and the engagement members continuing on in their closed paths move forwardly spaced beneath the support surface and ultimately to the pick-up station ready for engagement on the timed basis with the leading edge portion of a next scrap skeleton sheet that has now arrived at the pick-up station. Selectively adjustable side edge guides of the support surface are provi…
