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 ( 13 a, 13 b; 14 a, 14 b; 23 a, 23 b; 24 a, 24 b), d) the in each case corresponding coupling parts ( 13 a, 13 b; 14 a, 14 b; 23 a, 23 b; 24 a, 24 b) 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 (a 1 ) between the holding-device-side coupling parts ( 13 a; 14 a) of the first coupling devices ( 13, 14 ) being smaller than the spacing (a 2 ) between the holding-device-side coupling parts ( 23 a; 24 a) of the second coupling devices ( 23, 24 ), and/or the maximum longitudinal extent (b 1 ) of the first roll ( 10 ) between its end sides being smaller than the maximum longitudinal extent (b 2 ) of the second roll ( 20 ) between its end sides, and/or the maximum longitudinal extent (b 1 ) of the first roll ( 10 ) between its end sides being smaller than the spacing (a 2 ) between the holding-device-side coupling parts ( 23 a; 24 a) of the second coupling devices ( 23, 24 ).
