ABSTRACT:
A spreader roll that operates to convey flexible sheet material in its manufacture via a bowed shaft which supports a plurality of thermoplastic bearing units which are spaced laterally on the shaft by spacers to maintain a clearance space between sleeves in the bearing units. The end bearing units have sleeves and bearings therein that are sealed from external contaminants by a locking sleeve, an annular seal and end caps. A cylindrical sleeve encompasses all of the bearing units and is operative to contact the sheet material to be conveyed.
