Delpro – Meyer Rod & Air Knife Coaters
Mayer rod coaters are a simple, undemanding method of applying a range of low to medium viscosity, aqueous and solvent based coatings to a variety of film, paper and textile substrates. Delpro Mayer rod coaters extend the limits of this coating method with the following key features:
- Fully and independently adjustable coating yoke reduces ‘slack edge’ problems and lifts web automatically from coating applicator roll on ramp-down, or ‘stop coating’ command.
- Driven ‘turn-round’ roll maintains tension over the Mayer rods, independent of tensions downstream.
- Two rods in tandem of stepped gauge and independently controlled, give enhanced coating control.
- Double-wound wire on rods reduces coating lines; Air Knife eliminates them.
- Metering rod and Air Knife together can achieve coating speeds up to 500m/min with excellent results.
- Remotely controlled edge wipers allow fine adjustment of uncoated selvedge.
Option available:
Pre metered applicator roll and Air Knife only units.
