The accumulator has the function to change the roll during winding, without stopping the complete extrusion line. It can also be used as additional cooling track. These accumulators are recommended for the larger sheet extrusion lines were higher line speeds are occuring.
The accumulator is available with a buffer length of 36 m and 50 m.
The accumulator is composed of:
- Rollers built in aluminium complete with shaft and bearings;
- One servomotor with gear reductor used for moving the rollers up and down to store the sheet;
- Photo-electric sensor to detect the position of the rollers;
- Protective shielding around the accumulator with entrance door.
