Delpro – Ecograv Carbon Fibre Doctor Blade
Ecograv was the first adjustable trailing blade doctor chamber developed for applications such as reverse gravure coating and gravure printing where a reverse angle will not doctor efficiently.
Comprising a fully adjustable, oscillating enclosed doctor chamber with a volume of only 0.7 litre/metre of width made from corrosion free, lightweight carbon fibre, it enables cleaner, cheaper and faster, high quality printing, with reduced ink wastage. The enclosed chamber means reduced solvent evaporation resulting in a cleaner, safer working environment.
A fully adjustable trailing blade maintains an angle ± 25° even while printing, and micrometer adjustment of blade position to gravure roll accommodates change in gravure roll repeat length. A variable speed cam action air motor provides oscillation of the chamber to prevent preferential wear and build up of particles.
Chamber removal and guaranteed repeatable replacement is made easy by a two-point location of the chamber mounting system. A pneumatic blade throw on/off is also provided.
