In a method and an apparatus for printing on material in web form print images are successively applied to the web by a transfer cylinder. The web is continuously drawn into the printing station and the speed at which the web is moved in the printing station during a printing operation is greater than the speed at which it is drawn into the printing station. After the printing operation the web is positioned in the printing station for the following printing operation relative to the transfer cylinder which is not in contact with the web during a part of a revolution of 360&#xb0;, and at the same time the path of the web is altered in accordance with the change in the speed thereof. The web is driven by the impression cylinder which is associated with the transfer cylinder and around the peripheral surface of which the web partially passes. Positioning of the web for the respectively following printing operation is implemented by a change in the rotary movement of the impression cylinder.

Method and apparatus for printing a web

In an apparatus for decorating stiff objects, the objects are transported stepwise along an arcuate conveyor path. Printing stations and drying stations are arranged alternately along the conveyor path with the printing stations at a level above the conveyor path and the drying stations at a level below the conveyor path. Holders for the objects are reciprocatable upwardly and downwardly to permit vertical movements of the objects during the printing operation and/or for setting the objects in different heightwise positions in different stations. The holders for the objects are subdivided into first and second groups, wherein the holders of each group are adjustable in respect of height independently of the holders of the respective other group. The printing stations are screened from view in relation to the drying stations by screening members.
