Abstract (en)
A web-fed offset printing press suitable for production of business forms, having a series of printing stations (5) in each of which an inked image is printed from a plate cylinder (6) to a blanket cylinder (7) and thence offset to a web (P) running against an impression cylinder (8). In order to realize fine adjustment of the rotational speed of the impression cylinder and hence to cause the web to be fed under proper tension by the impression cylinder despite possible variations in paper thickness, cylinder diameter, etc., two separate drive linkages (e.g. gear trains) are provided, one (13a) for driving the plate cylinder (6) and blanket cylinder (7), and the other (13b or 13b') for driving the impression cylinder (8). The drive linkage (13b) for the impression cylinder has a speed changer (20) coupled thereto. The two drive linkages are coupled to a common drive source in one embodiment and to separate drive sources in another. <IMAGE>
