ABSTRACT:
A regulating dispenser comprises a hopper and a movable surface for withdrawing material from the bottom of the hopper to the outside thereof. The movable surface is constituted by at least one area arranged so that the regulating dispenser does not deliver over the whole of its width. A movable delivery regulating valve and a scraper independant of the valve and bearing on the movable withdrawing surface are provided. The scraper is fast to the fixed wall of the hopper and bears elastically on the movable surface so as to ensure sealing in said at least one area from which the dispenser does not deliver.
