  • Patent number: 4976129
    Abstract: The apparatus transmits a high shifting force reliably and has a simple and rapid assembly. The axial shifting occurs by a clamping device which is in releasable working connection with the roll stub shaft of a rolling-mill roll or the rotating shaft. The disengageable clamping junction is formed between the clamping device and roll stub shaft shaped to fit together. Especially the clamping device is formed as a compact unit comprising a clamping head with at least one axially precompressed compressible spring which acts on a plurality of clamping disks working as a clamping body. The clamping disks force a radially elastic clamping sleeve to grip the roll stub shaft. The clamping disks are releasable from a clamped position by a hydraulic pressurized medium against the action of the compressible spring. The clamping disks are supported axially on the one side on a portion of a housing of the clamping head and on the other side by an axially slidable hollow cylinder acted on by the compressible spring.

  • Patent number: 4895195
    Abstract: An apparatus for dosing a fragile bulk material has a supply bin having an inclined wall formed with a throughgoing aperture and a filler for maintaining the supply bin filled with the bulk material up to a level below and not above the aperture. Thus the wall aperture is always above the level of the material. A slider formed with a throughgoing aperture like the wall aperture is slidable along the wall between a lower position with the slider aperture wholly below the material level and out of alignment with the wall aperture and an upper position with the slider aperture above the level and aligned with the wall aperture. An actuator reciprocates the slider between its positions and thereby fills its aperture with a dose of the material in the lower position, moves the dose up above the level while shedding material atop the slider on movement into the upper position, and drops the dose through the wall aperture when in the upper position.

  • Patent number: 4795201
    Abstract: A method of knotting with a clamp adjacent an axis and a two-jaw knotting head rotatable about the axis comprises the steps of first wrapping a strand around an object to be trussed with the strand ends together and gripping and retaining the strand ends together in the clamp with one of the strand end portions passing under the jaws of the knotting head and then upward to the object, the other strand end portion passing over the knotting head between the one end portion and the axis and then downward to the object, and the strand end portions crossing between the knotting head and the object being trussed. Then the knotting head is rotated through less than one full revolution with the jaws closed together to bring the crossing point of the strands onto the jaws and loop the one end portion around the jaws. The jaws are then opened and the head rotated through the balance of the revolution to engage both end portions between the jaws between the clamp and the axis.
