Cylinder Rolling

Our 2 roll bending machinery forms virtually 'flat free'  cylinders or segments from flat blanks in one pass.  It is ideal for volume production of cylinders of known diameter.  A steel mandrel and urethane tyred roller are forced together by hydraulic pressure and the blank passed between.  The blank is forced to follow the mandrel, producing a cylinder a fixed amount larger than the mandrel.  A mandrel sleeve is required for each cylinder diameter to be rolled. 

The latched top roller hinges out for cylinder removal, which can be automated along with the blank feed for continuous production.
