Abstract
A turntable assembly for a stretch wrapping machine comprises a frame, a hub rotatably mounted to the frame on a shaft, a turntable mounted to the hub, and a plurality of rollers rotatably mounted to the frame defining a generally horizontal supporting plane for the turntable. Each roller has an axis of rotation generally parallel to the supporting plane and generally passing through the turntable axis of rotation. The frame is constructed so as to elastically deform, upon a load being placed upon the turntable that results in the load not being evenly supported by the rollers, to permit the roller axis of rotation to tilt relative to the horizontal supporting plane while still passing through the turntable axis of rotation.
