摘要

The edge folding machine for bending plate comprises a frame with two gables, an under beam extending between the gables and comprising a counter surface for a tool (5) pivotable to and from the under beam. The drive for the tool comprises eccentrically placed arms (10,11), which are pivoted with the aid of an alternating current motor, which allows the tool to move along an eccentric path, where the movement speed during a bending phase is considerably less than during a feed speed until the tool has come into contact with a workpiece fed towards the underbeam.
