A two-apron drafting unit comprises at least one sliver guide which projects into the wedge-shaped gap of the roller pair which follows the apron unit. The sliver guide has a defined distance from the surfaces of the roller pair and can be moved within certain limits in the longitudinal direction of the roller pair. The sliver guide is arranged in a holding device which is aligned in parallel to the roller pair as well as with respect to the height of the drafting zone plane. The holding device, which has a slideway for the sliver guide, is arranged on a supporting part which is connected with the lower deflection guide for the bottom apron.
