Abstract
Abstract Apparatus for collecting fibrous material preparatory to baling including fiber feeding, fiber collection and fiber discharging means so designed as greatly to reduce the contamination and loss of the fiber during the process. Specifically, the fiber is fed to a support member located alongside the charging or collection chamber where streams of air lift and move the fiber from the support thereby to deliver the fiber into the charging chamber. The chamber, near the place where the fiber is fed thereinto, is provided with a perforated section through which the carrier air for conveying the fiber is removed and which prevents loss of fiber. The interior of the apparatus is maintained under subatmospheric pressure. Fiber holding dogs are provided with cover plates to seal about the openings in the sides of the chamber when the dogs are in fiber holding position, during the packing operation. Certain moving relatively slideable portions of the packing means are continuously subjected to downwardly moving currents of air to prevent accumulation of fiber thereon.
