ABSTRACT:
An apparatus and process for mar free handling of sheet steel pieces and blanks die cut therefrom in a press, in which load and unload trolleys are used with vacuum pickup and transport of the sheet steel piece and blanks from respective locations at the front and rear of the press. A pusher slides the sheet steel pieces off a low friction platform at the front of the press and onto a non scuffing but smooth and soft bed liner, and the cut blank is raised with the die by an array of vacuum cups each partially recessed into the die board. A table is extendible from the rear of the press to be positioned beneath the die and receive the blank thereafter released from the die cavity. The table is retracted to allow pick-up therefrom by the unload trolley.
