    Folding apparatus comprises a longitudinal folding device (1), a first transverse folding device consisting of a folding blade cylinder (2) provided with spikes or grippers and of a folding flap cylinder (3), and a second transverse folding device consisting of a gripper folding blade cylinder (4) and a folding flap cylinder (5). A tape transport device, which consists of an upper tape (6) partially encompassing the circumferential surface of the folding flap cylinder (3) and of a lower tape (9) partially encompassing the circumferential surface of the gripper folding blade cylinder (4), is arranged between the first and the second transverse folding device for the further guidance of products transversely folded once, and a stripper (12) on the folding flap cylinder (3) of the first transverse folding device is arranged in operative connection with the lower tape (9). <IMAGE>

    The invention relates to folding machines with one device for longitudinal folding and two devices for subsequent transverse folding, which are particularly advantageous to use on high-speed newspaper rotary machines.
    Folding machines with two successively arranged devices for transverse folding are known, in which the first device for transverse folding consists of a knife cylinder provided with graphs and grippers and a valve cylinder, and the second device consists of a knife cylinder with grippers and a valve cylinder. Tyurin A. Automatic printing machines. M. 1980, p. 338.
    The disadvantage of these folding machines, especially on high-speed rotary printing machines, manifests itself in the second cross-folding device, where the folding speed is possible relative to the first cross-folding device and the double-fold folding across the printed products is possible only with a throttled printing speed. This depends on the sophisticated control of the grips located in the knife cylinder, which, when the cylinder rotates, capture the printed product, which alone must be received from the folding valve valves of the first cylinder that open at the same time. At the same time, the opening angle of the grips should be very large, and the steering angle, due to unfavorable geometric relationships, should be very small, so that already at low folding speeds very large accelerations and mass forces occur, with increasing rotation it is difficult to control.
    The purpose of the invention is to increase the productivity of the folding machine while preserving its advantages in such a way that it is possible to fold on all the folding devices without reducing the possible printing speed of the rotary press.
    The goal is achieved by placing the first and second devices for transverse folding of the belt conveyor.
    The drawing shows a schematic folding machine, side view.
    The folding machine consists of a first device for longitudinal folding, which is a folding funnel 1, and a first device for cross folding with knife 2 and valve 3 cylinders, as well as a subsequent second device for cross folding with knife cylinder 4 with grippers and valve cylinder 5. Between the two devices for transverse folding there is a belt conveyor, consisting of a guide of the upper blade 6, which partially covers the lateral surface of the valve cylinder 3 and the belts 7 which veduts rollers 8 and the side surface of the blade cylinder with grippers 4 and guide backsheet 9 which partially encloses the knife cylinder with grippers 4 and the belt 10 whose rollers 11. At veduts valve
    the cylinder is the squeegee 12. The drawing also shows a belt conveyor 14 leading to the drum and 13 and a real cylinder 15.
    During the folding process, the paper web passes through the folding hopper 1 and longitudinally folds. The longitudinally folded, longitudinally folded paper web Q, guided through the guide rollers to the knife cylinder 2 and the cutting cylinder 15, is cut by the cutting cylinder 15 into specimens of a corresponding length and each printed piece cut in this way is picked up by the graphs of the knife cylinder 2 and is transported further along its side surface until will not be
    5, the first transverse fold is produced by immersing the folding knife of the knife cylinder 2 into the folding valve of the subsequent valve cylinder 3.
    The printed product folded in the transverse direction, while simultaneously retracting the grates, is captured by the folding valves of the valve cylinder 3 and at the last, after turning approximately 120 °, is brought under the moving guide of the upper web 6 and transported further between it and the side surface of the valve cylinder, until the printed product With the aid of the squeegee 12, do not remove it from the side surface of the cylinder after preliminary opening the folding valves and between the guide of the upper blade 6 and the direction the lower blade 9 will not reach the partially covered last knife cylinder with grippers 4.
     There, the printed product across the width of the surface covered by the ribbons 10 is received by the grips of the knife cylinder 4 and advances on it until it receives between the cylinders of the second device for transverse folding by means of a folding knife of the knife cylinder with the grips 4 in functional interaction with a pair of valve valves. cylinder 5 second transverse fold and will not be stuck by the same pair of valves. By
    5 the side surface of the valve cylinder 5 in accordance with the embodiment of the printed product is directed to the belt conveyor 14 and from him to the bar

    Invention Formula
    A folding machine containing a device for longitudinal folding of a printed product and two devices for transverse folding, the first of which includes a knife cylinder with graphs and grippers and a valve cylinder, and the second one contains a knife cylinder with grippers and a valve cylinder, characterized in that, in order to increase performance by providing a constant speed of the apparatus, it is installed between the first and second devices for
    a river folding belt conveyor for further advancement of a printed product with one transverse fold, consisting of upper and lower cloths, the upper 6 of which partially covers the valve cylinder 3 of the first device for transverse folding, and the lower sheet 9 partially covers the knife cylinder 4 with grips of the second device for cross-folding, as well as a squeegee 12 mounted on the valve cylinder 3 of the first device for cross-folding with the possibility of interaction with the lower blade 9 of the tape tra sportera.
    Recognized as an invention according to the results of the examination carried out by the Office of ps invention of the German Democratic Republic.
