Pneumatic circuit for cascade feed at controlled pressure and temperature to ventilated driers or boxes of a machine or of a production line with many driers or boxes. The object of this cascade-type delivery is to reduce the masses of air extracted from the total pneumatic system and consequently to cut down the amount of energy used for heating or purifying. This circuit is intended more specifically for multicolour printing presses or machines for varnishing or pasting paper as well as all kinds of webs for making flexible packaging. <IMAGE>
