Continuous-feed inking units of a printing machine, and a roller in this printing machine

The invention relates to continuous-feed inking units (11) of a printing machine and to a roller in this printing machine, each with improved delivery behaviour. The continuous-feed inking unit (11), in the roller train, may have a continuous-feed roller (01) and at least one roller (17, 22) arranged downstream of the continuous-feed roller (01), wherein this downstream roller (17, 22) has a lateral surface (02) made of an elastomeric material, and the elastomeric material has a multiplicity of randomly distributed cavities (07) which are open at the lateral surface (02) and are directed into the interior of this roller.; In the case of the roller with the elastic lateral surface (02), the sum of all the cavities (07) on its lateral surface (02) in excess of the respective non-productive volume is greater than the volume of the fluid which is transferred from the lateral surface of this roller. Provision may also be made for the cavities on the lateral surface (02) to have flanks with surfaces which are in co
