Abstract: The invention relates to a shiftable transmission (1) having at least two shifting levels, preferably for use in rolling mill technology, said shiftable transmission comprising: a rotatably mounted input shaft (20), to which an input torque an be applied; a rotatably mounted first output shaft (30) and a rotatably mounted second output shaft (40), which are arranged parallel and are connected to each other by means of an output transmission stage in such a way that aid output shafts rotate oppositely, preferably at the same rotational speed, when an input torque is applied to the input shaft (20) at any shifting level of the shiftable transmission (1); a first coupling (50), which is designed to selectively connect an disconnect the input shaft (20) and the first output shaft (30), a first shifting level of the shiftable transmission (1) being realized in the coupled state, in which first shifting level the input shaft (20) and the first output shaft (30) are connected to each other in such a way that the input torque is transferred from the input shaft (20) to the first output shaft (30) without step-up or step-down, preferably without redirection and without a spur gear stage.

Abstract: The invention relates to a roll stand (2) for rolling, in particular cold-rolling, metal products, comprising at least one actuator (16) which can be actuated for actively damping vibrations in the roll stand (2), and at least one supporting roll (10) which is non-adjustable or can be adjusted exclusively via a readjusting device for pass line adjustment (13) of the roll stand (2) for supporting a working roll (5) and/or intermediate roll of the roll stand (2), wherein the supporting roll (10) is guided at the ends via a respective bearing unit (11) on a rack (8) of the roll stand (2). In order to enable an optimal active damping of vibrations in a roll stand (2) of this type with low engineering effort, the invention proposes that the supporting roll (10) is supported on the actuator (16) via at least one bearing unit (11) and that the actuator (16) is supported on a section (17) of the rack (8) either directly or indirectly via at least one component (14) of the readjustment device (13)
