Reverse roll coater type «BA-RRC»

Multiple roller applicator for the application of primers, lacquers, solvent-containing, aqueous and 100% systems, UV lacquers as well as pretreating agents onto aluminum, steel sheets and other materials. The plant conditions can be reproduced on a small sample size as various parameters such as roller speed and roller distance can be set precisely.

The dip roller rotates, partly immersed in a trough mounted below the roller. The applied liquid is transferred from the dip roller to the application roller. The distance between both rollers can be set precisely and measured on precision dials. The speeds of both rollers can be infinitely varied individually and read off on the digital displays. The application roller is equipped as a standard with polyurethane with a Shore value of 50–55°. The applied liquid is transferred onto the samples by the application roller. The transport roller with a covering of polyurethane with a Shore value of 45–50° moves the sample through underneath the application roller and ensures regular application over the entire length of the sample. The speed of the transport roller is infinitely variable. The distance between the application roller and the transport roller can be set precisely to the required sample thickness and read off on a precision dial. The transport roller can be moved pneumatically. The direction of rotation of the transport roller is reversible, permitting application in both directions.

Options
Transport of the material samples either by a transport roller or belt
Variable lengths of in feed and discharge tables
Variable number of rollers
Different roller materials
Pressure sensors for measurement of the roller contact pressure
