ABSTRACT:
A textile fiber feeder includes a feed chute adapted to be charged with fiber material and having a lower portion constituting a zone in which a fiber lap is formed from the fiber material; a measuring arrangement for measuring a distribution of the fiber material along the feed chute width and for generating signals representing the distribution of material; a sensor member forming part of the measuring arrangement and directly responding to the distribution of fiber material; and arrangement for generating an air flow in the feed chute for affecting the distribution of the fiber material; and a regulating arrangement for controlling the air flow along the feed chute width as a function of the signals. The regulating arrangement includes a setting member arranged for directly altering the air flow. The sensor member and the setting member are arranged in an adjoining relationship in the zone where the fiber lap is formed.
