Abstract

Abstract A feeding apparatus in pressing machine which performs sequential predetermined pressing operations on a workpiece at two or more working positions spaced by given intervals, which includes a holder means provided in such a manner that it can be reciprocated between adjacent working positions a suction means that is held by said holder means and which stops applying suction to the workpiece at one of said working positions, and a pivoting mechanism for pivoting said holder means to a position where it does not interfere with the pressing operation of said pressing machine, the workpiece under suction of the suction means at one working position being sent to the next working position by the movement of the holder means and retracted to said non-interfering position by pivoting said holder means after said suction means stops applying suction to the workpiece and before the pressing machine starts to operate.
