ABSTRACT:
A low mass transport shaft is formed by crimping a thin wall tube to form two opposed grooves along the length of the shaft. The two grooves impart rigidity to the tube structure enabling it to be used for such purposes as a paper transport shaft. In the embodiment shown, a pair of feed rollers are rigidly attached along predetermined points on the shaft, the rollers rotate with the shaft, and serve to move objects in contact therewith such as paper along a predetermined path.
