The device is essentially composed of a feeding roller (15) with compartments (19) in a house (16) and a supply of detergent. Since the detergent is highly hygroscopic it is important to prevent moisture from penetrating into the supply. The roller is therefore made of an elastic material and separates a filling opening (20) and an emptying opening (21) in the house. The roller is rotated in portioning intervals by a motor (18) controlled by a program control device. |
