Abstract
An improved closed chamber baler includes a hopper into which is fed waste paper or other compressible materials to be baled. The material to be baled is forced into a bale chamber by means of a piston operated ram. Means are provided for sequentially guiding a strapping wire about the outside periphery of the compressed material at a plurality of vertically spaced intervals along the compressed material. The strapping wire is tensioned and then twisted or knotted together to form a continuous strap about the compressed material, thereby forming a bale. When the bale has been completely strapped, the compression ram is retracted and an output gate is opened. The bale is then ejected from the bale chamber by an automatic bale ejector. While the invention is disclosed in connection with baling waste paper, the closed chamber baler is capable of other uses, e.g., the baling apparatus embodying the principles of the present invention may be found useful in connection with the strapping of a wide variety of other articles to which multiple strapping loops are applied thereabout sequentially at vertically spaced intervals.
