Abstract

A hopper feeder for blending and feeding textile fibers is disclosed which includes a chute (3) having a bottom conveyor belt (5) and an upwardly inclined spiked lattice (6) for reducing and opening the fibers, and inclined surface (4) is disposed in the chute and extends at least half the length of bottom conveyor belt (5), and receives textile fiber from an overhead reciprocating feeder. A freely rotatable roller (11) maintains a column of fibers in working relation with spiked lattice (6). A door (15) is provided below inclined surface (4) through which textile fiber may be fed directly.
