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.

Abstract: The piece of packaging material (e.g. a sheet or plastic placed on the topside of the fiber material to be compacted exhibits marginal zones projecting all around, which must be detached from the press ram after the compressing step and must be placed against the bale. For the automatic detachment of the sheet from the press ram, leaf springs are fastened for this purpose at the side faces of the press ram and urge, after withdrawal of the press box casing, these marginal zones away from the press ram. Subsequently, the press box casing located there above again travels downwardly to the bale, namely only up to the top rim of the latter, during which step the marginal zones of the sheet projecting from the bale in the upward direction are uniformly brought into contact with the bale.
