POWDER COLLECTOR CONSTRUCTION

摘要

A construction for collecting excess powder in a system which involves the application of powder to a moving surface such as the surface of sheets issuing from a printing press. The collecting construction is located adjacent the powder applicator to pick up powder which does not attach itself to the sheets or other surfaces to thereby reduce the amount of powder entering the surrounding atmosphere. The collecting means comprise a plurality of modules with each module including enclosing walls with inlet and outlet openings being provided. The modules are supported in end-to-end relationship adjacent the applicator, and conduits are provided for the passing of powder from the modules to a suction system.
