Abstract
A process of and a feeding device for feeding material in fibre form to a machine for preparing the material for subsequent spinning includes a material feeding bin through which the material is continuously fed to a substantially horizontal feeding table situated approximate a rotary preparing roll. The horizontal feeding table and the approximate rotary preparing roll define an air gap therebetween. A feeder roll is located above the feeding table which conveys the material toward the air gap, and the feeding table is supported to move in a substantially radial direction relative to the rotary preparing roll under the influence of data detected by a detecting device which detects the impurity level of the material at a point upstream of the feeding table relative to the direction of fibre flow.
