Abstract
Extrusion coating of circular and other substrates is taught with a linear extrusion head in a linear motion utilizing a chuck assembly providing a coating bead forming surface. The coating bead forming surface allows for the coating bead to be at a steady state at all points at which the extrusion head interfaces with the substrate during the linear motion. Various configurations of chuck assemblies are taught to allow for improved handling of the substrate, deploying of the chucks in existing machinery, and simplified cleaning of the coating bead forming surface. Additionally, adaptation of the chuck assembly for discouraging undesired migration of the coating material is taught.
