The machine is designed for semi-automatic working management.
The web coming from the pre-dryer section is guided by paper-guide rolls through the size press. Subsequently, while the cylinders rotate in synchronism of speed with the machine, the operator controls the closing down of the press.
The opening of the nozzles is automatic when the appropriate photoelectric sensors indicate the presence of a full size web in the machine.
The approach of the cylinders is very fast, whilst the definite closure is slow; this is to avoid breakage of the paper.
The operator sets up the work pressure on the NIP and the PLC process runs all the sequences, the hydraulic unit and its pumps in accordance with the safety procedures.
The use of the cleaning doctor in fixed or oscillating mode is chosen by the operator.
