Abstract (en)
[origin: WO2018136851A1] A domer station (10) having a domer assembly (12), a housing assembly (14), and a stacked piston assembly (60) is provided. The domer assembly (10) is movably disposed within a domer body passage (40) located in the housing assembly (14) and structured to move between a forward, first position and a retracted, second position. The stacked piston assembly (60) includes a plurality of pistons (62), preferably three pistons (62A, 62B, 62C), disposed in series and a pressure supply (50). The pistons (62) are disposed behind the domer (12) in pressure chambers (64). The pistons (62) have a constant pressure applied thereto and are biased towards the domer (12). The pistons (62) are, however, each restrained by a stop (80) and do not contact, or operatively engage, the domer (12) when the domer is in the domer first position.
