Corrugating Machine

Realizing high quality and stable productivity required in the world.

Contributing to stabilizing quality of corrugated boards and increasing revenue.

Mitsubishi offers high-speed "STEADY STATER" concept corrugating machines, SH-400 series that boast maximum production speed of 400 meters per minute, as well as diverse lineups, including H series corrugating machines, which can realize optimum productions based on customers' needs. We will propose the best suitable machine according to customers' requirements such as labor saving, less maintenance, and environmental friendliness.

General Specifications

SH-400 (Double Cut-off type)

60N

60N Single Facer applies Belt Press System that Mitsubishi has more than 30 years experiences eliminating pressure-marks on corrugated boards. Full and Semi automatic cartridge changes are available to adapt as an option. Single cartridge type with forklift is also available. Peripherally heated corrugating rolls are equipped as standard.

Advantages

60N Single Facer equips with automatic loading and unloading cartridge function with automatic pressure belt support bar and automatic piping connections in order to achieve the cartridge change within 4 minutes.

61N/62N

Wrap roll remote adjustment device and process control function are equipped as standard, the amount of preheating can be optimally controlled. Contributes to labor savings and improve corrugated board quality.

Preheater model 61NT

Advantages

A variety of preheat drum configurations with warp roll on each preheater are available depending on individual customer's needs for flutes and production speeds.

63N

63N Mill Roll Stand reduces operator work and makes it easier to change paper rolls.
Increase arm opening/closing & lifting speed and shorten the cycle time of paper roll change significantly.

Advantages

It realizes smooth web feeding with excellent tension control up to maximum diameter of paper roll (i.e. 1,524mm diameter roll) at all production speeds in case of light/heavy weight paper rolls.

63-1N

63-1N Auto Splicer boasts faster paper splicing speed at 584 m per minute for medium paper. Equipped with tension control system to prevent wrinkles and stabilize paper splice.

Advantages

It realizes stable and reliable splicing performance at variation of production speeds with light/heavy weight of paper rolls equipped with exit roll tension control device.

65J

The rider roll is placed with the glue applicator roll horizontally to reduce glue splash significantly. The glue amount applied on corrugated boards can be controlled optimally using process commander.

Advantages

The application of positive cell of glue applicator roll brings constant glue amount, reduces glue splashing, and makes cleaning easily. Edge wiper for glue applicator roll is available as an option to reduce glue accumulation on heating plates.

66N

In order to operate various types of paper and flutes stably at high speed, Mitsubishi designs high performance 66N Double Facer incorporating unique technical know-how. It applies non-crushing air bag system to realize stable bonding regardless of flutes and production speeds.

Advantages

The application of thin type heating plates increases heat efficiency and realizes quick heat response and less steam pressure than conventional. Air bag type loading system uniforms forming pressure on corrugated boards. Zero pressure is also available.

67-1N

67-1N Gamma Changer realizes "Gapless Order Change" during productions to change orders without interruption.

Advantages

Water jet type center cutting device with high pressure water pump and edge cutting device realize continuous order changes without production interruption and corrugated board webs are stably running before/after job changeover.

67N

67N Slitter Scorer is adapted tandem configuration and each station equips with two scorer shafts and one slitter shaft. Special scorer head is also available.

Advantages

Lower knives slit and the slitter heads are driven by servo motors, realizing to reduce defective sheets when order changes and to adjust knife height automatically.

68N

68N Double Cut Off is equipped with two pairs of light-weighted knife cylinders with lower inertia to reduce energy consumption and achieve high production speed with high accuracy of cutting.

Advantages

It applies two sets of measuring wheels separately from Cut Off unit located at rotary shear and at infeed conveyor independently to warrant high accuracy of cutting.

DE245/DE248

Double Down Stacker dedicated for Mitsubishi corrugating machine is supplied in collaboration with NE Engineering, Italy.

Advantages

Unique "PIN head" and "Squaring Plates" features are applied to realize excellent sheet stack quality.

Sigma 2000N

Sigma 2000N production control system maximizes the performance of corrugating machine and ensures easy operations with high productivity for frequent order changes and short paper cycles.

Defective Flute Detector (DFD) (Option)

The system is observing running corrugated board web and check the flute height measuring the flute shadow pitch by camera. If the pitch become abnormal, the production control system tracks its point and discharge it after Cut Off automatically without operator's intervention.
