Abstract

See full text

A maintenance-free valve for impeding the flow of fibers in a high velocity air-fiber stream. The valve has a rake-like construction to impede fiber flow when in the closed position. The valve has a plurality of closely-spaced, parallel tines attached to a rotatable shaft that is perpendicular to the tines. When closed, fibers collect on the tines of the rake valve, blinding the valve to further fiber flow. When opened, the fibers are dislodged from the tines such that they re-enter the air-fiber stream.
