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.
