TOPSTAR 3400 is a revolutionary roller coating machine especially designed for colour coat and top coat application on smooth and embossed leather for automotive and upholstery use.
With TOPSTAR 3400 it will eventually be possible to finish leather without involving spray cabins with great economical advantages and with respect for the environment.

This technology will guarantee:

• Reduction of chemical consumption from 50% up to 70% both for colour and top coat
  
• More uniformity and better distribution of pigments and chemicals on the entire leather surface also including light weight areas.
  
• Coating quantity ranging from about 1.5 to 4.0gr/sq ft (15-40gr/sqm) for each pass.
  
• Thanks to better coating efficiency it is also possible with a single pass to correct dark tones to lighter tones.
  
• Use of chemical product with no water added (higher percentage of dry components).
  
• Catalyst mixing ʻin lineʼ immediately ahead of the feed pump to optimize chemical consumption.
  

TOPSTAR is equipped with numerous innovative operating features:

• Transport roller independent from feed and spreading conveyors.
  
• The technical approach compensates even for high thickness variations of leather and guarantees better precision of working thickness.
  
• If required the transport roller is very easily rectified.
  
• Engraved rollers can be re-engraved up to four times.
  
• Possibility of entering the real diameter of each roller on the touch screen panel when its own ʻzeroʼ working position will be recalled automatically.
  
• Working speed is variable up to a maximum of 20m/min.
  
• Doctor blade positioned on a very rigid support mounted
  on precision bearings to guarantee accurate movement; automatic system to compensate doctor blade wear.
  
• The stainless steel washing tank is equipped with a quick automatic exclusion system; this system is used to lower the tank to prevent the belt brush and the wiper roller touching the transport roller.
  
• All functions can be operated from a centralized control panel. The panel display shows working speed and it allows control of all machine parameters with the help of a guidance menu.
  
• Possibility of production data transfer to an external office through an ethernet port.
  
• Various optionals are available to optimize productivity and to implement the working data report.
  

Gemataʼs long experience as world leader in leather finishing combined with in-depth research and extensive laboratory and tannery experimentation work has led to the development of TOPSTAR 3400, a revolutionary and innovative machine the main distinguishing element of which are:

• Total absence of vibration in all moving parts
  
• Possibility of finishing all types of leather, smooth or embossed, at a very high rate of productivity.
  
• Extremely reduced downtime involved in the changeover of various articles, low maintenance and easy machine operation even by inexperienced personnel.
  
• All machine parts in contact with chemicals are protected with anti-adherent treatment to reduce cleaning time as much as possible when changing the process.
  
• Zero emissions: environment friendly technology, no more air pollution and no need of exhaust air scrubbers.
  
• Reduced energy consumption compared with traditional spray cabins.
  
• Low noise level (well below the amount permitted by law).
