ABSTRACT:
A feed duct (1) for feeding textile fibers to an associated processing machine is disclosed which includes adjustable wall elements (22, 23) to vary the width of the filling chamber (5) of the duct and discharge a fiber web of corresponding width. The adjustable wall elements (22, 23) are displaceable parallel to the side walls (31, 32) of the filling chamber and include lateral wall elements (22a, 23a) which are bent and extend through the side walls to also act as holding elements. Setting elements (26, 28 and 27, 29) adjust the setting of the wall elements and the chamber width. In a duct feed having an oscillating plate 39, adjustable wall elements are provided as double wall elements (43, 44) with a pivotal wall part (45, 46) carried between the double walls of each element. An inclined edge (51) of the double wall elements allows oscillating plate (39) to swing with respect to the adjustable width duct for compaction of fiber. A column of fibers may be provided over the entire height of the filling chamber having a uniform width.
