Coating of extruded profiles and apparatus therefor.

摘要

A coating apparatus and process for coating selected surface areas of an extruded substrate with decorative or functional coatings, passing the extruded substrates (52) emerging from the extrusion die (12) past a coating block (10). The coating block (10) contains a coating cavity die conforming to the selected surfaces to be coated, and liquid coating material is supplied to the coating cavity die in a manner to selectively coat the selected surfaces on the extruded substrate.
