Accumulator / Buffer
The accumulator (or buffer) has the function of storing the sheet during a roll change, without stopping the complete extrusion line, but it can also be used as additional cooling track. The accumulator is available with a buffer length of 36 m and 50 m. An accumulator is recommended for a sheet extrusion line with line speeds > 25 meters/min.
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 lockable entrance door.
