The present invention relates to a roller frame which includes at least two rollers which are supported by a housing. A roller nip is formed between the rollers. The ends of the rollers are rotationally supported by a bearing. At least one roller is implemented as a location setting roller. The roller frame includes a control system. The bearing of the location setting roller is moved under the change of the roller nip by the control system. The control system includes a rack and a pinion which is engaged with the rack and is rotated by the motor. In that case, a distance between the pinion and the rack is changed under the change of the engagement depth. |
