  • Patent number: 5412844
    Abstract: A sawless lint cleaner receives the cotton as doffed from the gin stand in an airstream. The lint is deflected toward spiked cylindrical rollers of a cleaner and wiped across a grating at a speed about equal to the airspeed. The grating is in cylindrical segments as close to the spikes as tolerance will permit. The grating is composed of parallel bars approximately 5 mm thick spaced 13 mm apart and angled about 15.degree. from the radial line of the shaft of the spiked cylinder. Trash passes through the grating. The lint is reunited with the air at the end of the cleaner and conveyed to a condenser. The condenser separates the air and forms the lint into a batt for further cleaning by a typical saw lint cleaner.
