Abstract
An apparatus for supplying suction air to a rotary applicator comprises suction rollers planetating about a central shaft. Each suction roller carries suckers arranged in an axial row and the shafts of which are mounted in spaced discs secured on the central shaft. Two control valve discs connect the conduits leading to the suckers to a conduit leading to a suction air pump over a zone corresponding to an approximate angle of rotation of 90.degree. of the discs. The first control valve disc is formed directly by one of the discs mounting the suction roller shafts and the second control valve disc is secured in the frame and held in sealing sliding contact with the disc.
