摘要： Apparatus for the forming of a strip, formable at increased temperature, in particular of a strip consisting of thermoplastic, in a continuous run on the surface of a rotating drum which is to be heated and/or to be cooled in predetermined stationary regions. In order to reduce the energy losses due to the heating and cooling alternation, the thin-walled drum is mounted on a carrier body which can be heated or cooled in the respective regions and is heat-exchangeable with the drum surface at least in these regions.

摘要： Roll for a roll stand having an exchangeable roll ring and a divided roll body, the two parts of which each form a tensioning flange and are interconnected by a central tensile connection. An axial tensioning device is provided which comprises a threaded device for transmitting the forces acting between the two parts of the roll body and for their basic setting, a hydraulic tensioning device for tensioning the arrangement and a mechanical fixing device for fixing the hydraulically produced state of tension. According to the invention, the central tensile connection is limited to a central section of the length of the roll and it comprises the threaded device. The hydraulic tensioning device and the mechanical fixing device are arranged on the external circumference of the roll. At least one of the two parts of the roll body preferably forms a radial seat which interacts with the bore hole of the roll ring including a clearance for assembly and which can be spread apart by means of a wedge device provided in the tensile connection under the force transmitted by the tensile connection for removing the clearance for assembly. The wedge device can be formed by the inclined flanks of a thread inside the radial seat (radial seats).

摘要： Arrangement for changing the nut (11), the latter holding a roll ring, on a cantilever-mounted roll shaft (2) having a thread (13) for the nut (11), by means of a changeover apparatus. This has a threaded sleeve (50) which is provided with a thread (12a) that matches the thread (13) of the roll shaft (2) in order to take the nut (11). It has a centring device (49) for placement in alignment against the roll shaft (2). To ensure that the nut (11) can be screwed onto the roll shaft (2) from the threaded sleeve (50) even when the position of their threads does not match exactly, the threaded sleeve is moveable and inhibited against rotation in relation to the centring device (49) and/or in relation to the roll shaft (2).

摘要： An arrangement for fastening a roll ring (5) to an overhung roll shaft (1) by means of a taper sleeve (8) which transmits essentially the entire torque and which is loaded axially by a spring (43) supported on an abutment (47) adjustable on the free end of the roll shaft. The roll ring can be exchanged easily because of a cylinder part (21) arranged radially within the spring. This cylinder part forms a first annular cylinder space (40) for prestressing the spring, with which it interacts via a flange, and a second cylinder space (22) for drawing off the taper sleeve, to which it is connected via engagement means (28). The spring and the hydraulic devices can remain in place when a roll ring is assembled and removed, because their outside diameter is less than the bore of the roll ring.

摘要： An electrode carrier arm for an electric arc furnace consists of an arm part (10) and of a electrode-clamping device and is produced so as to be current carrying from a material of high conductivity. Between the arm part and the electrode-clamping device there is a flanged connection consisting of flanged plates (11, 12) which limit a cooling-liquid cavity (20, 29) on both sides and which themselves contain passage orifices (21) for the cooling liquid from one cooling-liquid cavity to the other. This allows an effective cooling of the flanged plates and consequently a direct supply of current via the flanged connection when the carrier arm is produced from light metal.
