Tissue Paper Making Machines

OVERMADE  is universally acknowledged as a leader in the manufacture of tissue making machines on account of the outstanding quality, softness and properties of the paper produced on them. We have manufactured tissue machines since the early 60's, developing and mastering the whole technology of tissue making: from the early fourdrinier to the suction breast roll, from twin wire to crescent former.

To cover every  production target, OVERMADE  delivers a wide range of tissue machines, starting from the simple and low-investment model designed for productions  between 40 and 60 t/day, up to the most advanced model for 250 t/day - 5650 mm trim width.

Overmade Tissue Machines Features:
 

  • Flexible and Efficient
  • Energy Saving
  • Simple to operate
  • Low Maintenance Required
  • Easy Production Changes
  • Saleable Jumbo Rolls from the very start up

Paper Machinery Yankee Dryers

OVERMADE has supplied Yankee cylinders all over the world for a variety of grades, from creped tissue to coated board.

Our Yankees are offered in two versions:
 

  • With shell made of cast iron mounted by means of bolts on heads and journals made of nodular cast iron
  • With shell made of steel, covered with a special hard metal, mounted by means of bolts on heads and journals made of nodular cast iron


Requirements covered:
 

  • Inner surface:  plain or grooved
  • Operating pressure: 5,   8.5 and 10 bar
  • Diameter:  from 3200 mm to 4877 mm without face length limitations
  • Special shell coating

Hydraulic headboxes paper making

OVERMADE headbox family extends from the traditional air-padded, two-roll headbox for application on low speed fourdriniers to the hydraulic headbox Dynaflo for high speed formers and Crescent formers.

Hydraulic headboxes are conceived to guarantee:
 

  • Excellent stock dispersion through the exclusive Dynaflo device for turbulence generation
  • Best sheet formation
  • Negligible residual wake signature on the jet


Options:
 

  • Edge flow control system capable to modify locally the flow from 60%  to 160% of the nominal flow to optimize fiber orientation.
  • Stiff lamellas in the slice area
  • Multilayer layout
  • Dilution system for CD profiling control

Paper board formers

OVERMADE FORMING SECTIONS cover all paper grades, production speeds up to 1500 m/min and trimmed widths up to 8 meters.

OVERMADE can offer:
 

  • FOURDRINIER:  Former to produce single and multi-ply grades up to 1200 m/min.The fourdriniers feature beams of cantilever type and are equipped with state-of-the-art drainage elements and ceramic blades.
  • OVER-TD: Top wire drainage unit to increase the drainage capacity of the Fourdrinier wire and to improve formation and fines distribution in Z-direction. Used for communication papers and packaging grades at production speeds of 1300 m/min.
  • OVER-HS: Gap former for the production of communication grades at high speeds.
  • OVER-HSB: Gap former designed for application on packaging grades, speeds up to 1500 m/min and basis weights ranging from 70 to 160 g/m2.


Gap formers combine roll and blade for the sheet forming process to ensure the highest drainage capacity together with an excellent sheet quality.

Press Section Paper Machine

Overmade Press family covers all paper grades and production speeds. Single and double felted layouts are available with Suction Press roll, plain press rolls and Over XL shoe press or crown controlled press rolls.

Our Presses are categorized into:
 

  • OVER Press-I: compact no-draw, triple nip press. Ideal for rebuilds and modernizations of the wet end area.
  • OVER Press-II:  a combination suction pick-up/press roll, generating two nips. This configuration is one of the most successful press designs, ensuring great water removal capacity and optimum sheet non-two-sidedness.
  • OVER Press-IIIXL: modern design of a no-draw, three-nip press. Having a separate pick up roll, the first nip press is a double felted press with a Suction Press roll. The second nip is a single felted press. The third nip press roll is again a single felted press usually equipped with an OVER XL shoe press.
  • OVER Press-HL: double felted Jumbo press for linerboard and cardboard grades. The press (single or tandem layout) consists of two large diameter rolls providing a very long nip and high press impulse.
  • OVER Press-V: press of modern design for application on high

Soft and Hard nip Calender

Hard nip calender with 1 to 5 nips, equipped with a combination of:
 

  • Variable crown rolls (VC-E and VC-S) in King Roll position
  • Thermo-rolls of peripheral or central bore type in Queen Roll position


Soft nip calender with 1 nip (two rolls configuration), or with 2 nips (available with 3 rolls configuration, or 4 rolls back-to-back configuration).

The calander is equipped with:
 

  • Variable crown rolls (VC-E and VC-S) in King Roll position
  • Thermo-rolls of peripheral or central bore type in Queen Roll position.


The special cover of VC roll allows to reach the best results in terms of paper bulk, smoothness and gloss.

The thermo-rolls are heated with superheated water, steam, or diathermic oil.

When a VC-E roll is applied, the roll face can be divided into multiple independent zones – from 3 to 7 - to control the crowning locally.

The calenders are delivered complete with hydraulic unit, Queen roll heating system and controls.

Size Presses Paper Machine

OVER Sizer P:  of pond type design for the application of starch with standard consistencies of 8%.  Particularly indicated for paper basis weights exceeding 100 g/m2, OVER Size press can run efficiently to a speed of 1100 m/min.

OVER Sizer R: size press equipped with rod applicators of different designs to apply starch with consistency up to 6-8 g/m2 per side and lightweight pigments on all paper grades. The sizer is followed by an air turn unit and/or by IR dryers.

Size press roll available diameters are: - 1000 mm - 1280 mm- 1500 mm
