Flexrod Coater

A development on from the Metering Rod Coater is the Flexrod Coater, whereby the rod is loaded, via a pneumatic loading tube, onto a backing roll. By varying the air pressure and therefore the rod load pressure, the coating weight can be controlled. Profiling screws are used to profile the rod to the backing roll.

Again predominantly used as a pre coater or back wet coater for boards, however the Flexrod Coater gives the boardmaker more control over the coating to be applied and a wider range of operation than the Metering Rod Coater.

The Flexrod Coater can also be employed as a top coater to a pre coated web.
