ABSTRACT:
An automatic feed mechanism for sheet steel forming equipment such as a power brake or the like is provided. The mechanism comprises essentially four sections. The first section provides a support for a stack of sheets to be fed to the power brake. The second section contains a suction cup and actuating cylinders for lifting a sheet vertically from the stack and for transporting the sheet horizontally to a roller. The third section comprises a roller upon which the sheet is transported horizontally to a lifting bed at the fourth section and a drive for the roller. The fourth section of the mechanism comprises a lifting station positioned adjacent the power brake. The lifting station includes an elevator for engaging the ends of the sheet to raise the sheet from a first level equal to that of the level of the rollers to a second level substantially equal to that of the input to the power brake. The elevator provides sufficient support for the sheet in the raised position so that a single operator can feed the sheet into the power brake for forming.
