• Excellent for performing tests onto small samples, hand sheets, and can also be used for continuous web coating. Can also be used to perform saturations and 2 roll pressure tests.
  

• Applies a uniform, consistent, and repeatable coating laydown every time.
  

• Used for applying coatings onto papers, paperboards, films, foils, glass, etc.
  
• Applies coatings down to as low as 1/10 of 1 micron (.000004”). High end thickness varies depending upon the viscosity of the coating, gravure pattern, and the type of substrate.
  

• Coat weight is controlled by the specific laser engraved gravure pattern in the bottom gravure roll and by the amount of air pressure that is applied to the top roll (bottom roll can be changed within 5 minutes to utilize various gravure rolls, rubber rolls, or chrome rolls).
  

• Top roll is 6” diameter x 12” wide standard neoprene rubber with air regulated vertical pressure for applying downward pressure onto the bottom roll, complete with dial indicators for adjusting the vertical position of the top roll in order to set a gap between the top and bottom rolls if desired .  Top roll is driven with a variable speed motor and controller digital rpm tachometer capable of approximately 30 fpm (available in 110 or 220 Volt).
  

• Bottom roll is 6” diameter x 12” wide laser engraved gravure, driven with a variable speed motor and controller with digital rpm tachometer (available in 110 or 220 Volt, 30 rpm motor).
  

• A Stainless Steel coating pan mounts underneath the bottom roll for holding the coating mixture. The bottom roll rotates in this coating pan and picks up the coating mixture, and then the pneumatic wiper blade meters the excess coating from the bottom roll. The coating that remains in the cells of the gravure roll then transfers directly to the substrate as it is fed between the bottom and top rolls.
  
• All control features mount inside a control panel that also contains an Emergency Stop button in order to shut off all power to the machine by simply pressing down on the button.
  
• Different types of rubber for the top roll including E.P.D.M., Silicone, Viton, Hypalon, Buna-N, Urethane, Polysulfide, and Natural Rubber are also available (prices vary).
  
• The customer’s choice of one (1) gravure roll up to 180 linescreen is included in the price of the direct gravure lab coater. If a linescreen of more than 180 is needed, then prices vary.
  
• Delivery time: 10 - 12 weeks

Pour the coating mixture into the stainless steel coating pan that resides underneath the bottom gravure roll. Apply the desired amount of air pressure to the wiper blade which meters the coating from the bottom gravure roll. Apply the desired amount of air pressure to the top roll. Set the desired speed of both the top roll and the bottom roll by observing the corresponding tachometers. As the bottom roll rotates in the coating pan, the wiper blade meters the excess coating from the bottom gravure roll and then transfers the coating directly to the substrate as you feed the substrate between the top and bottom rolls.
