Patent name Printing apparatus with a tensioned passage Drum Patent applicant Mann Roland Druckmasinger Principal applicant address Federal Germany Offenbach Inventor G. Schmidt Application (Patent) No. 200510051983.2 Application date 2005.02 .23 certification validation date Publication No. 1,660,570 specification validation disc 2005.08.31 announcement No. D0535 main classification B41F13 / 08 DOI B41F13 / 08 original divisional application number of priority items 2004.2.23 DE 102004008723.7 preferably as a rotary offset printing Abstracts The printing device drum according to the invention of the rubber roller of the printing press has a tensioning device (3) in a tensioning channel (2). By turning the tensioning device designed as the tensioning shaft (3), the side (8) which is the movement of the tensioning channel (2) can open this tight channel (2) so that the rubber cloth ends (4, 5) The tensioning channels can be introduced and can be closed by turning in the opposite direction, as shown in FIG. 1, with the ends (4, 5) of the blankets abutting each other. Therefore, the vibration caused by the change of the linear force is greatly reduced as compared with the previously used rubber cloth tensioning channel (FIG. 1). Sovereign Item 1. Printing apparatus cylinder, in particular a rubber cylinder of offset printing rotary printing press, which has a tensioning channel arranged in the axial direction, a tensioning mechanism arranged in the tensioning channel can be used to The end of the blanket tensioned on the drum is fixed in this tight channel, wherein the tensioning channel is defined by the side into which the end of the blanket can be introduced, which is characterized by at least one side (8') 18') can move in the circumferential direction (9,19).
