What is a grooved metering rod?
A grooved metering rod is a stainless steel rod that is rolled through a set of dies to form a thread into the rod surface. These rods are used in paper mills and converting mills to coat starches, pigments, adhesives and other coatings onto paper, films, foils, cardboard and a variety of other web surfaces. Threads can be created to conform to many profiles. These profiles can be customized to optimize the coating process, thus allowing for more precise and cost effective metering than that of wire-wound rods. These rods are usually chrome plated to extend working life.
