For regulating the speed of a motor vehicle, a control apparatus is equipped with an object detection system, and the reference speed is determined as a function of at least one preceding vehicle in the evaluation region of the object detection system, such that upon recognition of an imminent lane change by the regulated vehicle, vehicles in the adjacent destination lane are additionally taken into consideration for calculation of the reference speed by expanding the evaluation region in the direction of the destination lane, and consideration is given only to vehicles in the destination lane whose distance from the regulated vehicle is less than a predetermined distance value.

A roller, in particular an expander roller, for a web-processing machine, has a support core, which is braced in the region of both its ends via a respective bearing arrangement, and an outer covering, which in its axially central region is braced in a radially fixed manner in relation to the support core and in the region of its two ends is braced in a radially displaceable manner in relation to the support core by a respective additional bearing arrangement, whereby the radially extending center plane of both the support core bearing arrangement and the outer covering bearing arrangement lies axially within the outer covering. Preferably the outer covering is displaceable in this case in the region of its two ends respectively by an actuator arranged within the outer covering.

A rotary part, in particular a spreader roller for a web-processing machine has a supporting core with a longitudinal axis, said supporting core being mounted at its two longitudinal ends, and having an elastically flexible outer sleeve which surrounds the supporting core in its circumferential direction and extends, in at least some sections, between the two longitudinal ends of the supporting core. The outer sleeve on the supporting core is non-displaceably mounted on at least one bearing and that the outer sleeve is mounted on at least one displacing point at a distance from the bearing so as to be displaceable perpendicular to the longitudinal axis of the supporting core in order for the curvature of the outer sleeve to be adjustable.

The invention relates to a drying roll for drying a fibrous material web, in particular a paper, cardboard or tissue web in a machine for producing and/or finishing said fibrous material web. The roll can be heated on the interior by a gaseous heat transfer medium and the internal surface of its jacket is provided with elevated sections that extend at least radially inwards, the height of said elevations being greater than the average radial thickness of the condensate layer that forms on the internal surface of the cylinder jacket during operation. The roll is equipped with elements that drain condensate from the condensate chamber that incorporates the areas lying between the elevations. The condensate chamber or at least one condensate sub-section is in hydraulic contact with at least one front-end region of the cylinder.

摘要:
The invention relates to a drying cylinder which is used to dry a paper, cardboard, tissue or other web of fibrous material in a machine for the production and/or for the transformation thereof. The drying cylinder includes a support body and an external cover layer which is heated by a hot fluid. The thermal flow passing through the external cover layer is increased such that at least one cavity is provided between the support body and the external cover layer through which the fluid flows. The external cover layer is predominately so thin that the ratio formed by the thermal conductivity of the material and the thickness of the external cover layer is greater than a threshold value of 3.2 kW/m2K for steel, 30 kW/m2K for aluminum, 18 kW/m2K for bronze alloys, 3.4 kW/m2K for copper and 6.1 kW/m2K for magnesium.
