Abstract
For compensating for the lateral displacement of the ribbon (4) during the print operation in impact printers with revolving type carriers (9), an inclined pivotable roller (1) is used which is taken along by contacting the moving ribbon. This roller has a pivot (10) with a free end pivotable between two stops (11,12). If there is no lateral ribbon displacement to be compensated for, the pivotable roller is arrested in its respective current position and thus prevented from rotating. In the event of a ribbon displacement (LS), the pivotable roller rotating about its axis exerts a force component (LO) on the ribbon, counteracting the lateral displacement (LS).
