Abstract: Disclosed is a distance measuring system for measuring distance of a first transceiver from second transceivers, comprising the first transceiver having a first time zone, a second transceiver having a second time zone, and a control unit having a control-unit time zone. The second transceiver ascertains a time-zone relationship between the second transceiver and the first transceiver, and transmits the time-zone relationship to the control unit. The control unit receives the time-zone relationship, and ascertains, using the received time-zone relationship, a time-zone relationship between the control-unit time zone and the first transceiver. The first transceiver transmits at a defined instant in time or for a defined time period of the first time zone a distance measurement command to the second transceiver. The first transceiver transmits a measurement signal at a further defined instant in time, and the second transceiver switches from an inactive into an active receiving or measuring state.

Abstract: Method and a device for slitting a material web traveling in the run direction in which at least one knife unit with a cutting edge, and arranged on a carrier that is movable transversely to the run direction in a machine frame, is positioned. A measurement device measures the position. The position measurement is improved in that the measurement device has two measurement transducers. A first measurement transducer is arranged on the carrier and measures the distance from the cutting edge to a reference point that is fixed with respect to the carrier. A second measurement transducer measures the distance between a reference point that is fixed with respect to the carrier and a zero point that is fixed in the machine frame. The absolute position of the cutting edge is established by combining the two distances.

Abstract: Apparatus and process for processing material web. Apparatus includes a rotatable cylinder, in which material web is guided over rotatable cylinder, first fixed carrier, and at least three belt guide rolls, in which one of the at least three guide belts is pivotably coupled to fixed carrier. Endless belt is mounted on and guided by at least three belt guide rolls, where endless belt is guided over rotatable cylinder in a same direction as material web, and pivotably coupled belt guide roll is pivotably positionable between a tensioning position and a retracted position relative to endless belt. Second fixed carrier is provided and tensioning roll is positioned outside of endless belt and pivotably coupled to second fixed carrier, so that tensioning roll is pivotably positionable between a retracted position and a loading position of endless belt. Tensioning roll is further positioned between pivotably coupled belt guide roll and adjacent belt guide roll.

Abstract: Apparatus and process for winding a web onto a wound reel. The apparatus includes at least one king roll, at least one roll support unit, and a winding bed formed by the at least one king roll and the at least one roll support unit. A separating device includes a cutter located on a displaceable cutter holder, and support arms are swivelably coupled around a rotational axis of the at least one king roll. The support arms are coupled to the cutter holder. The process includes rotating the at least one king roll, such that the wind reel is rotatably driven, moving the cutter toward a gap between the at least one king roll and the at least one roll support unit, and rotating the cutter holder around the rotational axis of the at least one king roll. The process also includes pressing, with the cutter holder, the web against an outer circumference of the at least one king roll, and ejecting the reel from the winding bed, such that the web is separated along the cutter.
