Delpro's post metering coaters offer the combination of Mayer rod and/or Air knife coating for a simple, undemanding method of applying a range of low to medium viscosity, aqueous and solvent based coatings for a variety of film, paper and textile substrates.
Features are included to remove the inherent limitations of this coating method such as slack edges and coating lines
Fully and independently adjustable coating 'yoke' reduces 'slack edge' problems and lifts web automatically for start/stop coating.
Driven turnround roll stretches web over Mayer rods, independent of tension downstream, with optional load cell feedback.
Double wound wire on rods reduces coating lines, air knife or smoothing rolls eliminate them.
Remotely controlled edge wipers allow fine adjustment of uncoated selvedge.
Double skinned stainless steel blow off box with cooling prevents build up of coating in air knife mode.
Air knife with adjustable lip and control of angular and linear position provides optimum control of metering and coating quality.
