Abstract: An arrangement (1) and a method for optical measurement of a thread, in particular for measurement of an internal thread (12) on a sleeve or on a sleeve end of a metal pipe (11), are disclosed. The arrangement (1) comprises at least one optical sensor (5), at least one further optical element that can be adjusted relative to the optical sensor (5) and that is arranged on an optical bench (3) at a determined distance from the sensor along an optical axis (7) and is designed for optically scanning the internal thread (12), as well as means for acquiring and/or storing and/or evaluating the measurement data recorded by the sensor.

Abstract: A cross-rolling mill for rolling a block over a mandrel forms a hollow block. It includes a plurality of working rollers, each of which exerts a substantially radially aligned rolling force onto the block. The working rollers are supported in a roll stand, and the gap between the working rollers and preferably also the alignment of the rolling axis of at least one of the working rollers relative to the block can be modified. Hydraulic actuators, preferably hydraulic capsules, are provided in order to modify the rolling gap and preferably also the alignment of the rolling axis of at least one of the working rollers relative to the block.

Abstract: A cross-rolling unit and a method for setting the roll pass of a cross-rolling unit, having at least two rolls and a roll housing, in which at least one of the rolls is mounted such that its position can be adjusted in order to change the roll pass, allow the roll pass to be adjusted by means of a roll-positioning apparatus even during rolling, which roll-positioning apparatus is characterized by a housing-connected part and a roller-mill-connected part, which can be moved relative to the housing-connected part during rolling, which parts can be repositioned relative to each other, and/or which roll-positioning apparatus characterized by a drive which is dimensioned in such a way that rolling forces can be applied.
