A device for transporting elongated metal material comprises two chain drive units with a continuous chain, which are arranged such that the elongated material is passed through between the chains with frictional contact so that the elongated material is moved; two controllable pressure units configured to apply pressure forces to the chains towards each other; at least one controllable adjusting unit which is mechanically connected to at least one of the chain drive units and which is configured to move same in a longitudinal direction of the elongated material during operation. A plant can have such a device, and a process is used for controlling such a device.

A drawing bench of a drawing machine comprising a drawing carriage which is translatable along a predetermined direction on a base structure; a rack-pinion system adapted to translate the drawing carriage along said predetermined direction on the base structure; wherein the rack-pinion system comprises at least two motors; at least two pinions and one or more racks; and wherein each motor is adapted to drive a respective pinion.

A caterpillar track drawing method includes drawing a workpiece through a drawing die using a caterpillar track disposed behind the drawing die as seen in a drawing direction; and drawing a workpiece along a drawing line aligned parallel to the drawing direction while forming the workpiece by the drawing die. The caterpillar track includes circulating first and second drawing chains including chain links circulating parallel to a drawing plane. Each drawing chain is guided around first and second chain wheels having first and second axes aligned perpendicular to the drawing plane At least one measurable variable, inherent to the caterpillar track, of modules of the caterpillar track that resist or apply drawing force is recorded and optionally used for activation of a manipulated variable. In another aspect, a caterpillar track drawing machine includes the drawing die, the caterpillar track, and at least one measurable variable recorder.

A bridle device and a method for producing a steel strip in which snaking of a steel strip that occurs during production of a high-silicon steel strip is suppressed. The bridle device includes a pair of upper and lower rotatable endless belts or a pair of upper and lower rotatable caterpillars configured to pinch a steel strip. The bridle device is movable or swingable in a steel strip width direction by using a steering mechanism. The bridle device further includes a rolling reduction mechanism configured to perform rolling reduction on a pinched portion of the steel strip by using the pair of upper and lower endless belts or the pair of upper and lower caterpillars. The steering mechanism moves or swings the bridle device in the steel strip width direction, and the rolling reduction mechanism performs rolling reduction on one of end portions in the steel strip width direction.

In the case of a caterpillar track drawing machine having a drawing die and a caterpillar track disposed behind the drawing die, which track comprises two drawing chains having drawing tools disposed on chain links of the drawing chains, it should be possible to align the drawing tools of at least one of the two drawing chains jointly with the respective chain link, perpendicular to the drawing line, so that the caliber range can be changed, in simple and operationally reliable manner, between two drawing recesses having different caliber ranges. The latter is also possible if two different drawing recesses of the second one of the two drawing chains are intended for a first caliber range for which the first drawing recesses for at least one of the two drawing chains are intended, or if the drawing recesses of a first one of the two drawing chains deviate from the drawing recesses of a second one of the two drawing chains.
