Abstract:
Apparatus for producing a foil-wrapped pressed bale of material, the device comprising:a receiving device including an open cylindrical hollow body for receiving the material; a base plate arranged to close a bottom of the hollow body to support the material; a pressing device including at least one rotatable tapered compressor roller disposed within the hollow body above the base plate; drive transmitting mechanisms for rotating the receiving device and the base plate simultaneously about a common vertical axis, wherein the material is compressed between the compressor roller and the base plate; a first force-transmitting mechanism for effecting relative vertical movement between the pressing device and both the hollow body and the base plate during the simultaneous rotation of the receiving device and the base plate, wherein the base plate and the receiving device are separated vertically from one another as the material is being compressed to form a bale of the compressed material within the hollow body and seated on the base plate; a second force-transmitting mechanism for effecting relative vertical movement between the receiving device and the base plate, wherein the base plate and the receiving device are separated vertically from one another to cause the bale to travel out of the hollow body; and a winding device including at least one winding head carrying wrapping foil and arranged to wind the foil around the bale as the bale travels out of the hollow body, wherein the winding head is situated adjacent a junction between the hollow body and the base plate at initiation of the travel of the bale out of the hollow body.
