Abstract

The invention relates to an apparatus (2) for holding at least one roll (10) which rotates or can rotate about a rotational axis (A) and at least one second roll (20) of a rolling machine which rotates or can rotate about a rotational axis (B), having a) two first holding devices (11, 12) for the first roll (10) and two second holding devices (21, 22) for the second roll (20), b) at least one or at least two first coupling devices (13, 14) for the first roll (10) and at least one, preferably at least two second coupling devices (23, 24) for the second roll (20), c) each coupling device (13, 14; 23, 24) having at least two corresponding coupling parts (13a, 13b; 14a, 14b; 23a, 23b; 24a, 24b), d) the in each case corresponding coupling parts (13a, 13b; 14a, 14b; 23a, 23b; 24a, 24b) being connected in a form-fitting and/or force-transmitting manner to one another in the coupled state of the coupling devices (13; 14; 23; 24), for the generation of a torque-transmitting connection of each holding device (11, 12; 21, 22) to the roll (10; 20), e) it being possible for the respective roll (10; 20) to be released or removed from the holding devices (11, 12; 21, 22) in the decoupled state of the coupling devices (13; 14; 23; 24), f) at least in the decoupled state, the spacing (a1) between the holding-device-side coupling parts (13a; 14a) of the first coupling devices (13, 14) being smaller than the spacing (a2) between the holding-device-side coupling parts (23a; 24a) of the second coupling devices (23, 24), and/or the maximum longitudinal extent (b1) of the first roll (10) between its end sides being smaller than the maximum longitudinal extent (b2) of the second roll (20) between its end sides, and/or the maximum longitudinal extent (b1) of the first roll (10) between its end sides being smaller than the spacing (a2) between the holding-device-side coupling parts (23a; 24a) of the second coupling devices (23, 24).
