Roundo PM Quick rolling machines

Quick Rolling
Machines Type PM
ROUNDO QUICK ROLLING MACHINES TYPE PM

For high production of cylinders and tubes, the best solutions very often the ROUNDO Quick
Rolling MachreThe features of this machine are
Very short rolling times
Very good roundness tolerances and short straight ends
Less dependence on plate quality than other machine types
No demand for skilled bending operators to run the machine
High machine performance and bw maintenance costs

The PM machnes designed to prebend and roll the plate into a completed cylinder in one pass, and in very short cycle time. The two bwer rolls are fixed positioned, journalled in ball or roller bearings, and driven by a geared motor eqiupped with a brake. On most sizes, the lower rolls are equipped with support rolls under their mid point to reduce the defection of the rolls urder load.
The top roll unas are easy to change and takes a very short time. The interchangeable top roll unit consists of an inner non rotating shaft with joumalled rolls for each different rolling diameter.

Because of this design there is less load on the inner shaft and the interchangeable top roll than there would
Be on a conventional sold roll making it possible to roll to smaller diameters. One endof the inner shaft is fixed in the machine frame. The other end is supported from the frame by the yoke of a drop end, which is pneumat cally operated to allow the finished clynder to be manually removed automatically ejected. The upper part of the machine frame moves up and down during rolling ands powered by a hydraulic cylinder or cylinders, depending on machine size.
