More Information
Summary:A transport mechanism (28) for pulling and transporting a rotating open tube (16) in a downline direction, without distorting or closing the tube, and while allowing access to a central longitudinal cavity (60) of the tube from the downline side of the tube, is disclosed. The transport mechanism includes a plurality of drive rollers (30) positioned to engage the tube on only the outside of the tube. The drive rollers pull the tube downline without contacting the inside of the tube. The drive rollers are uniformly distributed around the tube and are mounted on preferably all of the sides of a regular polygon. The transport mechanism also includes a motor (78) which rotates the drive rollers around their respective axes and a motor (74) which spins the drive rollers around a central axis substantially colinear with the central axis of the open tube to rotate the open tube.
