Single-chamber baler device and method for forming and packaging bales by means of such a device

Single-chamber baler device intended for forming and, by way of a packaging material, packaging bales composed of a compressible material in the form of natural and/or synthetic fibers, comprising:

• a pressing and packaging zone, a packaging device configured for packaging a bale in the pressing and packaging zone, a top ram and a bottom ram, wherein the material is formed into a bale in the pressing and packaging zone between the top ram and the bottom ram, wherein the pressing and packaging zone is provided with an outfeed side along which a packaged bale exits the pressing and packaging zone, and wherein the packaging device comprises a film wrapper which is rotatable clockwise and anticlockwise and which is intended for packaging one part of the bale by way of anticlockwise rotation of the film wrapper around the bale and for packaging another part of the bale by way of clockwise rotation of the film wrapper around the bale, wherein the film wrapper is rotatable anticlockwise at least between a start position and a delivery position, and is rotatable clockwise between the delivery position and an end position, wherein the single-chamber baler device comprises a vertically adjustable press compartment with a number of press-chamber walls, wherein the adjustable press compartment can be adjusted between a pressing position, in which compressible material can be compressed in the pressing and packaging zone between the top ram, the bottom ram and the press-chamber walls) of the press compartment prior to the formation of a bale, and a packaging position, in which the side walls of the bale formed in the pressing and packaging zone are accessible to the packaging device, and in that the start position of the film wrapper is situated on the side situated opposite the outfeed side of the pressing and packaging zone.
