摘要:
A folding apparatus and method for a web-fed rotary press having a first folding jaw cylinder, a cross cutter by which a first web ribbon comprising a first quantity of printing stock webs is fed to the cross cutter and is cross cuttable into first print products by the cross cutter and a collection cylinder by which the first print products are subsequently cross folded by the collection cylinder and the first folding jaw cylinder. The apparatus also includes an auxiliary cross cutter which cross cuts a second web ribbon comprising a second quantity of printing stock webs into second print products. A transfer device is used to transfer the second print products produced from the second web ribbon to the collection cylinder. As a result, a first print product and a second print product are combined on the collection cylinder and are cross folded together when transferred to the first folding jaw cylinder.
摘要:
To provide close coupling between movable elements, such as segments (18) capable of varying the effective diameter of a folding blade cylinder (2) or a movable jaw (38) of a folding jaw cylinder, a first gear gear element (21, 47) is coupled via a positioning spindle (20, 43) to the respective movable element (18, 38); a second gear element (22) is coupled to the spindle (20, 43) and further rotationally coupled to the cylinder shaft (11, 35). A positioning or adjustment gearing, for example a differential, or a planetary gearing is positioned in close vicinity to a side wall of the machine, facing the respective cylinder, the positioning gearing being operable to be controlled to change the relative angular relationship between input or received rotation and output or delivered rotation, and being coupled to the second gear element (22), to receive rotation therefrom and further to the first gear element to deliver rotation and additional adjustment movement thereto. The adjusting gearing, which superimposed adjusting or positioning movement, is controlled by a positioning control element, such as a hand wheel (not shown), or a remote positioning control motor (30) coupled thereto by a gear, and controlled, for example, by a suitable electrical-electronic control unit, which can receive input data relating adjusting movement to, for example thickness of paper products being folded, number of paper products in a stack, and the like.

A cutting cylinder is mounted such that it can rotate and be driven and is provided with four cutting blades on its circumference, which blades divide the circumferential length into four sections arranged on the circumference of the cutting cylinder.
