Method and device for removing wires or tapes from pressed bales of raw material, in which the wires or tapes are arranged to form at least one point of intersection on at least two opposite bale sides. The method includes bringing the bales into an unwiring position, automatically determining a position of the at least one point of intersection, positioning a coiling device over the at least one point of intersection, severing the wires or tapes, and removing the wires or tapes from the bale by coiling the wire or tapes. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Method for removing wires or tapes from pressed bales of raw material and wire coiling device for carrying out the method

Process and apparatus for separating compressed material containing paper fibers where the apparatus includes at least three hammer rollers arranged essentially in a same plane and each hammer roller includes rotatable hammers. The process includes rotating the rotatable hammers, transporting the material over the at least three hammer rollers in a transport direction essentially parallel to the plane and transverse to the axes of the rollers, breaking up the material into fine material and non-fine material, and separating the fine material from the non-fine material by allowing the fine material to pass through gaps formed between the hammer rollers. The apparatus includes a machine frame and a plurality of rotors arranged next to one another in the machine frame. Axes of the driven rotors are arranged to lie in at least one plane, and the rotors are positioned to form free gaps between the driven rotors. A delivery unit, positioned above the plurality of rotors, is adapted to deliver the compressed material to the plurality of rotors and a removal unit, positioned below the plurality of rotors, is adapted to remove the processed material. The plurality of rotors include hammer rollers having shafts coupled to rotatable hammers, and a driver is provided for driving at least some adjacent hammer rollers in a same rotational direction.

Process for separating compressed material containing paper fibers

A process is disclosed that is utilized in particular in the preparation of fibrous material of used paper. Hot fibrous pulp friable materials, which are especially suitable for dispersing, are first formed in a compact, high-consistency fibrous material in the form of a plug. In a preferred embodiment, the plug of materials is pushed against a rotor that is equipped with pulverization elements. The pulverization elements remove the fibrous pulp friable materials and distribute them in a disintegrated condition in a processing chamber. In the processing chamber, super-heated vapor is supplied via vapor supply lines, which calefies the fibrous pulp friable materials, for example, by condensation.
