Procedure:
The material fed into the filling chamber of the press triggers the pressing process through a light barrier when the preselected filling level is reached. Depending on the bulk density and the type of cans and hollow metal bodies, a selector switch can be used to produce the press pack with one, two or three press strokes. If there is more than one pressing process, the press plate only moves just behind the cutting edge during the pre-press strokes. After the maximum pressure has been reached on the last stroke and the pressure has been relieved, the sliding door opens automatically and the package is ejected with the ram. This is followed by the return stroke of the punch and the closing of the press channel. The workflow for the next package can then follow. With the stroke preselection for the automatic ejection of the finished parcels after one, two or three strokes, parcels up to a maximum length of approx. 300 mm can be produced.
