In order to meter material (201) being applied to, for instance, a pattern board (140) a material supply (112) is connected to a nozzle (111) through a soft hose segment (203). This is supported by base or cradle (210) performing a movement forwards and backwards around a bearing (211). In this movement forwards and backwards the hose (203) will be engaged with an inlet cutting off body (221) and an outlet cutting off body (224) and a press head (230). This latter parts are protruding portions being mounted in a house (220). By giving these protruding portions suitable sizes in relation to the swinging movement of the cradle (210) inlet valve function and outlet valve function as well as a pressing out effect by means of the press head (230) are obtained. Furthermore, on the same time the movements of the nozzle (111) upwards and downwards are obtained. |
