DEVICES FOR ADJUSTING CONTACT PRESSURE EXERTED ON AN ADJACENT ROTATING BODY BY A ROLLER IN A ROLLER STRIP AND/OR FOR ARRANGING THE ROLLER ON THE ROTATIONAL BODY AND/OR FOR DISCONNECTING THE CYLINDER FROM THE ROTATING BODY

摘要

The invention relates to devices which are used to adjust contact pressure exerted on an adjacent rotating body (12, 13, 14, 16, 17) by means of a roller (4, 06, 07, 08, 09, 11) in a roller strip (N11, N12, N21, N31, N32; N41, N42, N51, 52, N61, N62) and/or for arranging the roller on the rotating body and/or for disconnecting the roller (04, 06, 07, 08, 09, 11) from the rotational body. The roller is mounted with the ends (18) of the axis thereof, respectively, in a roller lock (21) comprising several actuators (22) which act upon the roller. The actuators are impinged upon by a pressure means (41) which can be controlled in the pressure level (42). The actuators and, preferably, also the roller lock have an identification characteristic (m, n), such that for a selected roller lock, the contact pressure of a control unit, which can be actuated from a distance, exerted on the adjacent rotating body can be adjusted by means of the actuators thereof due to the influence of the pressure level (42).
