Abstract
A liner wringing device (10) is disclosed for use with a container liner. The wringing device includes a housing (30) with an internal cavity which houses the mechanical components of the wringing device. The housing defines a central liner compression channel (40). The internal components include a bottom support plate (42) with a central opening 43 aligned along the central channel. The wringing device also includes a drive assembly (44) formed by four elastomeric rollers (45) positioned so that the peripheral contact surfaces (50) are aligned generally tangentially with the central channel. The four rollers are each mounted to a drive shaft/axle which includes bevel gears which are meshed so that all four rollers rotate in simultaneous, synchronic rotation through the actuation of a pneumatic air gear motor (57).
