Abstract: The device is for cutting and removing wires from bales, such as pulp bales, paper bales and the like. The device has at least one cutting unit that has a cutting tool for cutting off a wire that is arranged around a bale, and at least one winding unit that has a winding tool for unwinding the cut wire from the bale. The cutting tool has an outer cutter and an inner cutter which are coaxially arranged and rotatable with respect to each other. Each cutter has a cutting edge which are arranged to be moved towards each other when the cutters are rotated towards each other in a certain direction, in order to cut off objects, preferably bale wires, between them.

Abstract: The device is for cutting and removal of wires from bales, such as pulp bales, paper bales and the like. The device is intended to remove all wires from a bale that is provided with at least two wires. The device has two cutting units and two winding units that are positioned pair-wise opposite each other, on one side each of a working location (W), for the pair-wise cutting off and removal of the two wires that are arranged in parallel.

Abstract: The present invention relates to a cutter for a raise boring head. The cutter is rotatable about a center axis and mounted, via a shaft of the cutter, in a saddle secured to the raise boring head. The shaft has ends that are secured to the saddle by a fastening mechanism. Bearings are provided between the shaft and a hub of the cutter in order to make it possible for the hub to rotate relative to the shaft. Seals are provided between the shaft and the hub, and the bore which is provided for introducing lubrication into the interior of the cutter. An expansion plug is mounted in the bore. The expansion plug is designed to accommodate the lubrication that enters into the bore from the bearings. A stopper is provided in the bore. The stopper encases a part of the fastening mechanism and is arranged to prevent mud from entering the orifice of the bore.

Abstract: A cutter mounted on a boring head includes a shaft and a roller body rotatably mounted thereon The greasing of bearings disposed between the roller body and shaft is achieved through an axial bore formed in the shaft and into which a filling plug is inserted. Grease is pumped through the filling plug and into channels in which the bearings are disposed. The filling plug is then removed, leaving the bore essentially grease-free. To prevent the escape of grease from the passage during a cutting operation, while accommodating thermal expansion of the grease, a grease retainer plug is secured in the passage. The retainer plug forms a space which communicates with the bearings for receiving thermally expanding grease. If the volume of expanded grease exceeds the volume of that space, the grease passes through a pressure relief valve and displaces a cover of the valve to create another space of gradually expanding volume for receiving the grease.
