Abstract: The invention relates to a converter gearing, comprising a gear rim (7), which is connected to the pivoting axis (6) of a converter box, said gear rim being engaged with at least one drive pinion (8) of the converter gearing (9) and at least one locking device, which can be pivoted to engage with and be disengaged from the toothed gearing of the gear rim, (7) in the form of a locking arm (12) that is positioned on a horizontal shaft (10) and configured with toothed gearing (11). The aim of the invention is to improve said locking device. To achieve this, the shaft (10) of the locking arm (12) is mounted in at least one terminal bearing (13, 13?) and the locking arm (12) can be engaged with and disengaged from the toothed gearing of the gear rim (7) in a non-positive manner, preferably by means of active force elements (14, 14?) in its end regions.

Abstract: The invention relates to a car (100) for transporting at least one drive spindle for a roller of a roll stand (300) and to a method for operating the car. The car comprises a running unit (105) for displacing the car from the operating side of the roll stand, through the roll stand, to the drive side, or vice versa, and the car is built flat enough that it fits under the drive spindles. The car according to the invention is an alternative to the prior art. Said car is designed as a lift car having a first carrier device (110) and a first drive unit (120), wherein the first drive unit (120) serves for raising or lowering the first carrier device (110), optionally having the drive spindle (200), relative to a neutral position.

Abstract: A device for controlling a discharge drop position of rod wire coils transportable by a horizontal conveyor and stackable in a vertical bundle build-up chute located beneath an end of the transporting conveyor and behind the transporting conveyor end in a transporting direction, with the device including friction brake element for impacting an outer circumference of the rod wire coils and located opposite the transporting conveyor end at a distance therefrom and beneath a charging opening of the bundle build-up chute in a drop region of the rod wire coils.

Abstract: A rolling stand has a frame and a pair of support shafts centered on respective parallel shaft axes and each having an outer end projecting past the frame, inner and outer axially spaced bearing portions in the frame, and a gear between the respective inner and outer bearing portions. Each outer bearing portion lies between the respective inner bearing portion and the respective outer end. Respective rolls are carried on the outer ends outside the frame and respective eccentric sleeves rotatable in the frame about the axes engage the shafts at the bearing portions so that a spacing of the axes can be varied by rotating the sleeves in the frame. Respective pressure sleeves surround the shafts between the respective inner and outer bearing portions and are connected to a controller that pressurizes the sleeves and thereby bends the shafts in the frame between the inner and outer bearing portions.
