Abstract

A fiber baling press consists of a rugged machine frame with a press ram in most cases movable from the top toward the bottom, a press box being movable underneath the ram. The press box consists of a press box casing which should be closed all around. This press box rests on a press box bottom plate which, in this case, for the pressing step, is simultaneously the lower press platen. The press ram as well as, in particular, the press box bottom plate are to be fashioned in the manner of a trough in order to impart to a piece of packaging material for the upper and lower sides of the bale of fiber a preliminary orientation directed toward the bale, after the press box casing has been pulled off the bale. A special advantage resides in making the bottom plate have a trough-like opening of the press box casing so that overflowing of the compacted fiber material over the four lateral flanges of the trough is avoided after withdrawing the press box casing. The piece of packaging material, e.g. a sheet, is to be aligned in parallel to the bale.
