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).

The present invention includes a control device and a control center having at least one cell defining an interior space with a front face for receiving and electrically connecting the control device therein. The cell and control device have mounting for mounting at least one electrical component thereon. The control device pivots on a pivotal axis within the cell so that a rear mounting surface pivots away from a cell mounting surface to provide access to the rear mounting surface and the cell mounting surface through the front face of the cell. The control device is releasably fastened to the cell to prevent pivoting the control device while the control device is electrically connected. A method is included with the present invention for providing access to the interior space through a front face of a cell in a control center with a control device inserted therein.

An open loop control system is disclosed for controlling the production of a web or sliver on a carding machine so as to have a uniform weight per unit length. A novel sensing arrangement for the card input is disclosed wherein corrections to the input are made at the same mechanical plane and point in the feeding process as where the input is sensed to provide highly accurate control of the weight of the output.

Apparatus for processing textile fibers is disclosed which includes a carding machine (14) and a batt former (A). Batt former (A) includes an air circulation loop which includes a plenum (B), fiber compacting chamber (C), air separating means (72, 74), acceleration channel (30), duct (46), and fan blower (54). Fan blower (54) has an adjustable angle of incidence "a"to direct a jet of fiber-laden air into plenum (B) against a splash plate (66) to cause fibers to be deposited in fiber compacting chamber (C) in a cross-directional profile so that fibers at side walls of the plenum may have increased residence time in the fiber compacting chamber compensating for side wall friction. A first separated air flow (5) is divided by side friction. A first separated air flow (5) is divided by side channels (92a, 92b) and combined with a second air flow (4) to form supercharged air flow regions at the sides of the air flow passing through acceleration channel (30). This accelerated air flow with supercharged side regions creates an air knife in combination with plate (26) which passes through teeth (28a) of opening roll (28) to doff fibers from the opening roll.

A textile apparatus for sorting fibers according to their length. A fiber opening device loosens and separates raw textile fibers transported by an air flow created by an air blower along an air path. A fiber extracting device extracts fibers having an average length greater than or equal to a preselected length from the air flow to produce usable long fibers and creates a separated air flow containing usable short fibers having an average fiber length less than the preselected length for subsequent processing. The long fibers may be compacted into a fiber batt. The usable short fibers may be compacted into a fibrous batt or may be passed through further fiber extracting devices. The apparatus may include a batt former which includes a plenum into which fibers are delivered by the air propeller or blower. The air blower has an adjustable angle of incidence "a" to direct a jet of fiber laden air against a splash plate to cause fibers to be deposited in a fiber compacting chamber in a prescribed cross-directional profile. The apparatus further includes a density sensor which measures the cross-directional density profile of the compacted batt.

Fluid treatment apparatus for textile fibrous material comprising a duct, a portion of which is enlarged to form a fiber treating chamber which includes an outlet opening, an inlet opening and a central passageway which extends between the openings and which has a surface which extends from a first point on the periphery of the inlet opening to a second point on the periphery of the outlet opening and extends no further from the longitudinal axis of the central passageway than the first point so that the surface is wiped by fiber entering the central passageway to prevent the accumulation of moisture near the inlet opening.

Fine opening mechanism for textile fibrous material which comprises a primary opening element such as a spiked beater roll and means for delivering a single undivided mass of textile fibers toward the primary opening element. A plurality of feed elements are located between the primary opening element and the feeding means, each of the feed elements forming a nip through which fibers are fed and presented to the primary opening element so that the mass of fibers are divided into a plurality of fibrous masses.
