A choice of laboratory coaters designed for both the direct and indirect coating of hand sheets, or a continuous web up to 300 mm wide. The range of Laboratory Coaters, including 3 roll offset Gravure, 2 roll direct Gravure and single roll, are designed for applying a uniform, consistent, and repeatable coatings.

Precise metering of coating from doctored gravure cylinders, give coating thicknesses from 1 micron to 125 micron.

Suitable for coating onto paper, paperboard, foamboard, polymer film, aluminum and steel foils, glass substrate, silicon discs, and various other types of substrate. Euclid Laboratory Coaters are extensively used for coating silicones, adhesives, hot melt coatings, U.V. coatings, paper coatings, inks, overcoat varnishes, and polymers.

Single Roll Lab Coater

Single Roll Lab Coater

220V Power Unit

Manual Unit

• Used for applying coatings onto small hand sheets of paper, film, etc.  The coat weight is controlled by varying the amount of air pressure that is applied to the doctor blade which presses against the back of the rubber covered roll.
• The manual unit contains a handle for rotating the roll.
• The power unit contains a 120 V or 220 V variable speed motor and controller.

Direct Gravure Lab Coater (2 Roll Unit)

Euclid Direct Gravure Lab Coater

12″ Wide Unit

12″ Wide Unit

• Used to apply various types of coatings onto various types of substrate, the coat weight is controlled by the specific gravure pattern in the bottom gravure roll and by the amount of air pressure applied to the top roll.
• 6” diameter x 12” wide standard neoprene rubber top roll is air regulated for varying downward pressure onto bottom roll, and also contains a vertical height adjustment with dial indicator read-outs for setting a gap between centre and bottom roll.  Independently driven with 110 Volt, 30 rpm variable speed motor and controller with digital tachometer for determining speed of centre roll.
• 6” diameter x 12” wide bottom gravure roll is also independently driven with a 110 Volt, 30 rpm variable speed motor and controller complete with digital tachometer for determining speed of bottom gravure roll.

Offset Gravure Lab Coater (3 Roll Unit)

Offset Gravure Lab Coater

12″ Wide Unit

Side Control Panel

• Used to apply various types of coatings onto various types of substrate, the coat weight is controlled by the specific gravure pattern in the bottom gravure roll and by the amount of air pressure applied to centre and top rolls.
• 3” diameter x 12” wide chrome top roll contains air regulated vertical pressure
• 6” diameter x 12” wide standard neoprene rubber centre roll is air regulated for varying downward pressure onto bottom roll, and also contains a vertical height adjustment with dial indicator read-outs for setting a gap between centre and bottom roll.  Independently driven with 110 Volt, 30 rpm variable speed motor and controller with digital tachometer for determining speed of centre roll
• 6” diameter x 12” wide bottom gravure roll is also independently driven with a 110 Volt, 30 rpm variable speed motor and controller complete with digital tachometer for determining speed of bottom gravure roll
• Stainless steel fountain resides underneath bottom gravure roll and holds coating mixture (bottom gravure roll can be changed within 5 minutes, so various gravure rolls can be utilised)

Options

• “Multiple System Lab Coater”  – features are the same as the Offset Gravure Lab Coater, except that a second wiper blade is mounted against the center roll for performing “Single Roll Lab Coating”
• Special “Removable Center Roll”  – feature for quick removal of Center Rubber Roll
• Hot Melt Option – can be added to any standard 12” or 18” wide Direct Gravure, Offset Gravure, and Multiple System Lab Coaters
  • Hot Melt Option comes complete with the following:
  • Two (2) Halogen Sealed Beam Infrared Lamps (mounted inside stainless steel holders), each lamp projecting an Infrared ray, one onto the surface of the “bottom” roll and one onto the surface of the “center” roll allowing both rolls to be heated to a maximum temperature of 275o degrees F
  • Two (2) Variable Output Temperature Controllers allowing independent and accurate control of the temperature of the Infrared Lamps for heating both the “bottom” roll and the “center” roll
  • One (1) Variable Temperature Controlled Heated Fountain (up to 275o degrees F.) for heating your coating mixture.

Please Note
The above machines include the choice of one “laser engraved” gravure roll up to 180 lpi (linescreen per inch).
Special pattern gravure or anilox rolls are priced separately.

Additional “laser engraved” gravure bottom rolls are available as follows:
Less than 180 lpi,  181 – 300 lpi,  301 – 440 lpi,  441 – 600 lpi,  601 – 800 lpi,  801 – 1000 lpi

Other types of engraving such as mechanical, electronic, chemical, etc., are also available [prices vary depending on specific engraving pattern]

Different rubber coverings and roll surfaces are available, such as EPDM, Viton, Silicone, Hypalon, Buna-N, Urethane, Natural Rubber, (prices vary depending upon the exact type of rubber or roll surface that is chosen).
