Subject to the coatweight and application Delpro offer direct, reverse and offset gravure coaters or a multi gravure coater offering all 3 modes.
They incorporate many advanced features for extreme accuracy of coating and ease and speed of operation, particularly roll changes, change of coating width and change of coating mix.
Rolls are pneumatically loaded against each other with a precision gap setting system with micrometer, backlash free adjustment which can be adjusted by hand wheel or servo motor.
Rubber covered offset or backing roll based upon a sleeve system to enable a change of coating width to be made within minutes.
All rolls are independently driven to enable relative speeds of the rolls to be varied for coating quality and small weight adjustment with motors housed on a separate drive frame and connected via quick release Cardon type couplings.
Coating is applied to the gravure roll via Delpro carbon fibre doctor blade or open pan with trailing blade.
Trolley mounted gravure roll as an option enabling make ready and cleaning to be done off machine and thus minimise downtime.
Gravure Coater - High Quality Coatings and Versatile Design
Delpro gravure coaters present the latest coating
technology in highly versatile and cost-effective form.
The multi coater design enables reverse, direct or offset
gravure coating in one head and with different specification
of gravure roll engraving providing a wide range of
coatweights.
FEATURES
Pneumatically loaded offset and backing roll with precision, pre-loaded backlash-free gap adjustment.
Interchangeable trolley system for make-ready off machine, hydraulically raised and locked in position.
Sleeve system rubber roll for ease of change of coating width.
Coating applied via carbon fibre chamber doctor blade with enclosed mix circulation system.
Optional oscillating trailing blade for some reverse gravure applications.
Independent drive to all rolls from separately mounted drive frame.
