The nozzle is provided with one or more cylindrical rollers, (FIG. 1 and FIG. 2), so suspended and so designed, by means of free wheeling bearings, so the rollers freely can revolve around their own axis, when the nozzle (14) is moved in one direction, but where the rollers are blocked, when moved in the opposite direction. Hair, thread and other foreign materials are thereby assembled in an oblong cylindrical cushion, easy to evacuate. The rollers can be provided with outside linings of different kind, for instance as a rubber roller, (FIG. 1), or as a brush roller, (FIG. 2). The rollers can be suspended in an activation device (7) and (10), making it possible to activate one or more of the rollers.
