ABSTRACT:
An improved fiber opening, mixing, and flow regulating apparatus and method are disclosed. The apparatus includes a textile fiber feeder (F) which opens, mixes, and regulates the flow of fibers from a ball (B) inside the feeder. A primary opening element is provided by a stationary spiked apron feed (I), and a secondary fiber opening element provided by a movable spiked apron (S). A gap (G) is defined between the opposing pins of the primary and secondary opening elements (I,S) which regulates the flow of fibers delivered by the feeder. By moving secondary opening element (S) in either linear or rotational motions, gap (G) may be modulated and the flow of fibers regulated. A controller (E) may be provided to receive a speed signal (54) representing the operational speed of a textile process downstream of fiber feeder (F) and a fiber quantity signal (16) may also be processed by controller (E) as well as various and other signals. A drive signal (18) controls the movement of secondary opening element (S) and the position may be fed back to the controller (E) by signal (52).
