Machine Description
Pos. 1.0 – Pneumatic Accumulator T4.0
Main structure in painted steel.
Accumulation capacity 40 Mt.
Material load is min. 0,01 kg/cm, max. load is 0.1 kg/cm.
Electric pneumatic command panel on console table and machine board L.S.
Electronic checking system of tension on accumulator.
The control system of tension on product is handled automatically by the touch panel; a proportional valve is controlled automatically; the tension adjusting on the product is automatic, different pressures can be set in the two phases of accumulation and disaccumulation, you can parameterize the pressures with proportional system from the beginning to the end of accumulation/disaccumulation.
