Model 91PL-A Automatic Index Rerolling Machine
Model 91PL-A Automatic Index Rerolling Machine   

The model 91PL-A is an automatic index, re-rolling machine to complete the parts formed with the 9000-sp mechanical bellows forming machine. This unit is completely self contained. It is electrically driven and hydraulic powered. This unit is controlled with a festo plc system for all manual or auto sequencing. Machines can be produced for large diameter bellows but must be ordered based on maximum diameter and length. This unit is ideal for bellows up to 18" (457mm) diameter and no more then 16" (406mm) long. It is equipped with a hydraulic press for collapsing the bellows after the mechanical form. It has an electronic system that allows for easy set-up of indexing in order for the o.d. and i.d. dies to line up the convolutions for re-rolling. Depending on the diameter and length, one part can be re-rolled from 20 seconds to 90 seconds. The o.d. rolling die lifts up and down automatically and the bellow is indexed automatically also using a stepper motor and a hydraulic cylinder. The cycle starts with a 12 volt foot pedal and utilizes 24 volt proximity switches.
