Abstract
Abstract A carding device of the large rotating carding drum type including a comber-cleaner assembly particularly well suited for combing and cleaning universal flat cards is provided. The comber-cleaner including a worker roller and a stripper roller mounted for cooperation with the carding drum is disposed between a take-in roller and a card belt. The comber-cleaner assembly includes at least three curved plaque segments disposed over the worker roller for defining at least two channels for positioning at least two extractor blades for improved removal of residual short fibers and other impurities. A control strip deforms the web as it passes from the stripper roller to the worker roller.
