This model is manufactured in a simple and rugged construction, suitable for high production as well as for the short runs and the R&D or model shops. Pressure on the bottom urethane roll is obtained by hydraulic pressure. The bending process for this machine consists of the rotation of the top roll (punch) by means of pressure developed by the lower urethane roll (female die). The radius obtained is a direct ratio between the diameter of the top roll and the spring back of the material being rolled. In order to obtain different radii other than the minimum one, it is necessary to slip over the top roll a tubular mandrel (slip-on tube), thereby changing the radius and naturally the diameter of the part being rolled.
Optional accessories can be provided for the loading of material into the machine via a magnetic or pneumatic feeding system. A parts ejector is also available for the off loading of the part either into a collection container or onto a conveyor system for transport of material into welding line.
