This machine was designed to prepare blanks for pressing. Thanks to the combination of three types of shaped rollers (interchangeable), a single machine can work in several different ways: - drawing of the disk for precise housing in the coining die (3 “A” rollers) - elimination of blanking burrs (3 “A” rollers) or (2 “B” rollers + 1 “A” roller) - hardening of the disk edge for better finishing of the knurled rim (2 “B” rollers + 1 “A” roller) - knurling of the disk rim (2 “A” rollers + 1 “C” roller) - blank edge striping (2 rollers “A” + 1 roller”C”) The two bottom rollers are powered by a ratiomotor connected to an electric motor (with foot pedal). The top roller is driven by a mobile slide (with an automatic pneumatic drive), which is powered by a pressure lever, and it has an adjustable mechanically controlled stop device.
