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.

Spreader roll

A method and apparatus is provided for continuously fabricating a high pressure hose, or the like, which includes axially advancing interconnected hollow mandrels through a plurality of winding stations wherein all of the hose building components are helically wound upon the advancing mandrels. A heat shrinkable webbing may also be wound upon the advancing mandrels so as to cover the hose components. The mandrels are then separated, and steam is introduced into the interior of the mandrels to effect curing of the hose components, with the shrinkable webbing acting to radially compact the components to remove air pockets and smoothly conform the innermost component against the mandrel. A method and apparatus is also provided for unwinding the shrinkable webbing from the hose after curing, and which includes a drive control system which advances the hose through an unwinding deck while insuring that the webbing being withdrawn from the hose is aligned with its take-up spool.
