Abstract
A sheet-fed printing press with a sheet feeder and a printing unit traction device connecting the sheet feeder and the printing unit to one another, the traction device having a taut side and a slack side, a phase-adjustment device acting upon the traction device for changing a phase angle between an input shaft and an output shaft by means of a change in the length of the taut side, one of the shafts being assigned to the sheet feeder and the other to the printing unit, the phase-adjustment device acting between the slack side and the taut side along a substantially vertical line disposed centrally with respect to the shafts, the phase-adjustment device comprising an adjustably disposed guide for the taut side of the traction device, and a guide for the slack side of the traction device, tensioning elements acting between the taut-side guide and the slack-side guide for prestressing the slack-side guide against the slack side of the traction device, the slack-side guide together with the taut-side guide being movable along the substantially vertical line so as to effect the phase adjustment, the tensioning elements being effective in a phase wherein the traction device is disposed.
