Abstract
A process and apparatus for blending fibers of a plurality of fiber flow is disclosed which includes a fiber feed device (2a, 2b, 3a, 3b) which feeds fiber layers (12) through an angular channel (13, 14) which rearranges the vertical layers into generally upright sections (12a) for transportation and weighing on a conveyor (14) by means of a weighing device (4a, 4b). The weighed fibers are delivered by intake rolls (32, 33) to a common opening roller (20) which opens and mixes the fibers according to a predetermined ratio as controlled by the weighing device. Fibers are discharged by a pneumatic source (40) to individual storage units (41), each of which may be made to store a different blend ratio.
