Abstract: An apparatus for reducing pressed fiber bales arranged in a row is disclosed which facilitates removal of fibers from the upper surface of the bales adjacent a stationary member (28). Transversely extending rollers (18, 19) parallel to milling rollers (4, 5) are provided with blocking means (25, 26). These blocking means may be actuated to prevent rotation of rollers (18, 19). As rollers (18, 19) are carried by housing (2) so as to extend slightly beyond the housing in the direction of travel (16). Upon reaching stationary member (28), blocking means prevents rotation of roller (19). The teeth of roller (19) act as a rake to remove fibers from bale (24a) adjacent stationary member (28) as reducing means (1) starts its travel in the return direction. In this manner, the fibers from the entire upper surface of bale (24) are more totally and uniformly removed.

Abstract: A condenser (1) for separating fibers from a fiber laden air flow is disclosed which includes a cell wheel housing (3) and a cell wheel (4). The cell wheel includes a plurality of radial vanes (6) and a perforated screen (12) extending between adjacent vanes. The perforated screen separates the space between the adjacent vanes into fiber entraining cells (14) and air exit spaces (13). Flexible sealing element (7) are carried at the ends of vanes which seal against an interior of the wheel housing. Air from the fiber laden air flow exits through screens (12) by way of a discharge opening (18). Fibers are discharged at (9) through an opening provided in the bottom of cell wheel housing (3).

A reciprocating tower is provided and supported for reciprocating alongside the row of said bales of fiber and has a cantilevered portion which extends over the row of bales of fiber at a height which is adjustable. Reducing means is supported by the cantilevered portion over the top surface of the bales for removing fiber therefrom. A horizontal channel is disposed adjacent to and above the reducing means for receiving fiber removed from the bale by the reducing means. The horizontal channel is connected to a telescoping vertical channel within the tower means for delivering fiber from the reducing means to the discharge channel in the tower when a suction force is created therein.

Abstract: Apparatus is disclosed for reducing bales of fiber which includes a tower that reciprocates alongside a row of bales. The tower has a cantilevered portion which extends transversely over the row of the bales and supports two milling rollers for removing fiber from the upper surface of the bales.

An adjustable vent permits passage of varying amounts of the atmosphere through the closed chamber. The closed chamber is connected to the horizontal channel so that air currents created by suction through the vent convey fibers removed from the bales by the milling rollers to a fiber collection point within the tower.

Thus, an equalizing effect is achieved for the removal of flocks from the fiber bales.

Abstract: A randomizing web former is provided for producing webs with greater degrees of isotropy than heretofore by including both a carding element, such as a worker roll or a carding segment, and an aerodynamic, centrifugal randomizing web former, employing a jamming action and then free flight of the web to randomize, both on the same toothed cylinder. Usually, the fibrous flock is worked into an array of axially parallel fibers by an assemblage of sequentially arranged carding cylinders and cooperating carding elements such as carding worker rolls and or stationary carding segments similar to flats but of complementary arcuity to the cylinders. Thereupon the web is moved to a toothed roll having both a carding element and a web former either in that sequence or combined so as to act sequentially or concurrently. The resultant randomized web is then doffed.
