The SRRL Carding Cleaner

A detailed description is given of an experimental machine somewhat similar to a downstroke buckley-type cleaner, but with the customary beater replaced with a licker-in type of carding cylinder. Also described is an improved feed system using a novel type of roll, called an "anti-pluck" roll. The new feed roll permits rapidly advancing a relatively thin layer of cotton to the carding cylinder, while simultaneously resisting the efforts of the carding cylinder to pull the cotton away. This results in opening the cotton to such a degree that cleaning efficiencies as high as 60-78% in a single machine are feasible at production rates of 400 lb per hr. Data are presented to show the per formance achieved in a quarter-size experimental machine.
