The system comprises of objects, having gaseous or fluid media, being transported on a handling cover (12), and set in a zone of the handling unit of the handled media. There is a securing cover (19) arranged, spaced and lying opposite the handling cover, permeably built for the handled media. The spacing (H), between the handling cover and the securing cover, sets the limit of the receiver chamber for the objects. The width of the securing cover may correspond to the width of the handling cover, and which may be coupled to one another. The rotation of the securing cover may be controlled independent of the rotation of the handling cover.
