A fulling mill's wheel is set vertically. It is connected to the spindle, placed in a pit and rotates together with the propeller. Oak wood planks, which lift the propeller and the mallet, are embedded in the shaft. Built into the water wheel are paddles which are inserted between the sides of the water wheel, and which are supported on protruded curved pieces of wood.
The upper part of the fulling mill also consists of beams that carry wooden mallets. The cloth is placed in a wooden box which is stroked alternately by one or the other mallet, each about 90 kg in weight, and each with a comb made up of three cogs. Additionally, a supply of water for moistening of the processed cloth is also supplied.
Apart from the fulling mills for domestic cloth, there were special tools for fulling rough bed covers and floor mats. It consisted of an ordinary, bigger barrel, with holes all over and without the upper surface. In the upper part of the barrel, a round shaped board was fixed on a horizontal, movable shaft, with a diameter slightly smaller than the barrel, with densely scored nickel-plated iron nails with the tips outside the board. While turning and rolling, the board was twitching woolen covers.
