Abstract: A device for de-linting cotton seeds is described that is of simple construction, does not damage the seeds and is antipolluent. The device comprises a unit provided with super-imposed discs spaced by a distance of the same order as the larger dimension of an at least partially linted cotton seed, the upper disc being fixed and the lower disc being rotary. Seeds are fed through a central opening in the upper disc and subject to friction between the discs as they migrate outwardly to the periphery where they are discharged and the lint removed is expelled from the device by an exhaustor. The lower discs are coated with a relatively rough surfaced rubber-like material and the lower discs are coated with a similar material formed with a plurality of finger-like projections whereby the seeds are subject to coarse friction from the lower disc while their toward migration is controlled by the retaining fingers. The device may have a plurality of such units in series.
