Abstract
A lint collection assembly for a dryer appliance includes a filter housing defining an aperture through which a flow of air exits the drying chamber. A roller assembly includes a supply roller for unrolling clean filter medium over the aperture and a collection roller for simultaneously receiving a used section of the filter medium. A drive mechanism, such as an electric motor is coupled directly to the collection roller or to a separate drive roller for moving the filter medium over the aperture between drying cycles to automatically and conveniently collect filtered lint.
