Abstract: A folding jaw cylinder for a printing press has a folding jaw arranged rotatably at the cylinder, a stop for the folding jaw, a rotary body, which can be nonrotatably connected to the cylinder, and whose angular position in relation to the cylinder is adjustable, and a gear mechanism for adjusting a working distance between the folding jaw and the stop by adjusting the angular position between the cylinder and the rotary body. The stop is arranged movably at the cylinder, and is adjusted in relation to the cylinder--during the adjustment of the angular position between the cylinder and the rotary body--by an adjusting arrangement, which is articulated to the rotary body and attached to the stop.

Abstract: A collecting cylinder for point folders of rotary machines, the circumferential surface of which consists of a number circumferential segments (5), which are next to one another in the direction of the cylinder axis but some distance apart, extend in the circumference in each case groupwise from point holes to point holes and are supported at one of two ends on bearings on eccentric shafts (6) and the radial interval of which can jointly be changed nonpositively. At least one eccentric shaft (6) of each circumferential segment group (5') is supported on bearings in the collecting cylinder so that it can be swung out radially and each eccentric shaft (6) is connected by means of an adjusting lever (10) and a connecting rod (11) with an adjusting disk (12), which is rotatably supported on bearings centrically to the collecting cylinder (1).
