The problem at this point in the processing of printed matter has been e.g. the correct timing of the different stages of the process and the control of the product stream. In the prior art, at the downstream end of the process, there are separate devices for folding and advancing the printed products 20-fold. These stand-alone devices each need their own product line for folding and folded printed matter, where the problem is' expensive and bulky hardware. Multi-component hardware is also more susceptible to failure, and as a result, such hardware also causes more repair and maintenance work. As a result, there will inevitably be more outages. Another disadvantage is that several separate laws. a lot of labor is needed to make tea.

It is an object of the present invention to overcome the above drawbacks and to provide an inexpensive, reliable, well-functioning, fast and minimized method and method. apparatus for handling a stream of printed matter. The method according to the invention is characterized by what is set forth in the characterizing part of claim 1 and the apparatus according to the invention is characterized. . that shown in the characterizing part of claim 4. Other embodiments of the invention are characterized by what is set forth in the other claims.

An advantage of the solution according to the invention is that printed products, such as newspapers, can be processed at the end of the process by simple and low-volume equipment. In addition, due to simplicity, the hardware as a whole is less sensitive to failures than more complex hardware solutions comprising several separate devices. It is also an advantage that the solution according to the invention does not attract a lot of manpower, whereby the manpower can be placed for more useful use.

The invention will now be described in more detail by way of example with reference to the accompanying drawings, in which Figure 1 illustrates the apparatus according to the invention in simplified and schematic oblique view and side view, Figure 2 shows the end of the apparatus according to the invention simplified and schematically and Fig. 4 shows a simplified and schematic plan view of a dispensing conveyor of an apparatus according to the invention.

Fig. 1 shows a solution according to the invention in which a uniform product stream of printed articles 4, such as newspapers, is introduced into the product stream distributor by means of a grab conveyor 1 which acts as a donating member. 2. When the gripper 8 of the gripper conveyor 1 releases its grip on the leading edge of the print product 4, the print product 35 can fall freely on the dispensing conveyor such that the rear edge of the printed product V is 113357 along its path toward the folding machine 10. Due to the construction of the dispensing conveyor 2, the printed products 4 in succession and overlap are separated at this point in a lateral direction relative to the direction of travel, and are denoted by reference numerals 4a and 4b.

The folding machine 10 comprises belt conveyors 13 having a conveyor speed higher in the main conveying direction of printed matter 16 than a conveyor conveyor. In this case, the belt conveyors 13 pull the printed products 4a and 4b away from the grip of the dispensing conveyor by the gripping means 9, and the conveyor conveying means 9, when empty, pivot back to the underside of the dispensing conveyor. The belt conveyors 13 of the folding machine 10 pull the printed products 4a and 4b under the folding knives 3a and 3b, where the position of the printed products is identified and the folding knives fold the printed products twice by printing on the center through the horizontal plane formed by the belt conveyors 13.

The feed conveyors 5 bring the folded printed products 4a and 4b; , Below it to a star wheel 6 which rotates about its horizontal axis divides the folded printed matter uniformly '·' ·, below the poistokul j ettimelle 7, 25, in turn, carry the folded printed uniform that - * / · tevirtana 4c further processing of the arrow 19 direction.

Figure 2 shows the remainder of the apparatus according to the invention in more detail, but still in simplified form. The belt conveyors 13 of the folding machine 10 are arranged in parallel. . cut into two groups so that the four belt conveyors of the first group transfer the printed product 4a to the delivery conveyor; - us 2 under the folding knife 3a and, respectively, the second group: 'four belt conveyors transfer the printed product 4b from the dispensing knife 3b under the folding knife 3b. Below the folding knives there are guide rollers 14, between which the folding knives are pressed for printing on the lower and lower assemblies '' 5, consisting of two pairs 5a, 5b and 5c, 5d such that the first pair 5a, 5b transporting the folded printed product 4a between them downward, and respectively the second pair 5c, 5d carrying the folded printed product 4b. Downstream Go-dis- placement five speed is so timed and lower ends to the mi-5 dimensioned and positioned, that the printed 4a and 4b fall extension conveyor 5 of the end head 11 alternately in the vicinity of the star wheel 6 of the compartments of the star wheel 6 rotates at a suitable speed of the arrow 12 direction. The sprocket wheel 6 is located either wholly or partially below the end of the conveyor belt 5.

Below the starwheel is an outlet conveyor 7, on which the folded printed articles 4a and 4b fall alternately off the starwheel. Discharge conveyor speed is synchronized with the star wheel 6 the velocity of pyo-15 in such a way that the printed putovat trays 11 partially overlaps the discharge conveyor and thus form a folded weight comprising the product stream uniform and smooth, flowing in the direction of the arrow 19, for further processing 4c.

Figures 3 and 4 show a distribution angle according to the invention. jet 2 in more detail, but still simple; plified. The distributor conveyor 2 consists of a fixed frame member 22 and a chain 20 on each side thereof, which are driven by the drive wheels mounted on the frame member: by means of a conveyor drive motor not explicitly shown in the figures. The chains 20 are provided with a plurality of consecutive guide bar pairs 21 disposed transversely to the movement path of the delivery conveyor 2, which move with the chains on the top surface of the delivery conveyor in the product flow direction 16 and return back below the delivery conveyor. Each of the steering rails; . rile 21 has one catching carriage 17a, 17b which is slidable in the longitudinal direction of the pair of handlebars, i. e. 35 in the transverse direction of the jet 2 with its two slides 23. The gripper carriage further has one guide roller disposed between the slide tubes 23 such that, in each direction of the product flow direction 16, the guide roller 24a is on the right edge of the gripper carriage and each other gripper carriage 17b is on the left edge of the gripper carriage.

113357 5 5 Within the distributor conveyor 2 is a guide rail fixed to the body portion, which is divided on the upper side of the dispensing conveyor, at the beginning of the conveyor into two arms 18a and 18b which divide from each other in the transverse direction of the dispensing conveyor. At their widest, the guide rail legs 18a and 18b are at one end of the distribution conveyor, whereby the horizontal distance between them corresponds to the transverse horizontal distance between the folding knives 3a and 3b of the folding device 10. At the delivery end of the delivery conveyor 2, the guide-rail rails, like the chains 20, pivot downwardly and backwards toward the front of the delivery conveyor. As the side of the distributor conveyor moves towards the front of the distributor conveyor, the guide rail arms 18a and 18b again approach each other in the transverse direction of the distributor conveyor and ascend at the upstream end of the dispenser conveyor like chains 20 at the top of the dispenser. and changing the direction of travel while the direction of arrow 16,. in the direction of the guide rails, the legs 18a and 18b are of one; ; the distance closest to each other. In this case, the successive trolley carriages 17a, 17b, which are guided by the guide rail, are * 25 each symmetrically on each side of the longitudinal center line of the distribution conveyor and successively on the same line. Every other gripper carriage 17a is controlled by the guide rail 18a and, correspondingly, every other gripper carriage 17b receives control by the guide rail 18b by means of guide rollers 24a and 24b. In this case, following their ohjauskisko- tarttujavaunut carrier and the differences in the passing direction of the arrow 16 by weight of the products 4a and 4b from each other transversely to the running mouth-7, with respect to 16. In this way, one product stream yields two:, separate product streams. The transport speed of the conveyor belt 2 is' * ·. 35 substantially the same as the delivery speed of the 4 V hand grab conveyor 1 printed on the delivery conveyor.

Each tarttujavaunussa 17a, 17b is further previously said gripping device 9 6 113 357, which engages the printed product 4a or 4b and to push it forward on the guide rod pairs 21 moves forward in the direction of the arrow 16. The grasping means 9 is actuated by a mechanism which opens the grasping means at each end of the dispensing conveyor 5 so that at the beginning of the dispensing conveyor the printed product can be taken in and at the end it can be released from the dispensing conveyor. The same mechanism closes the gripping member 9 on a straight portion of the dispensing conveyor both above and below the dispensing conveyor.

The printed products 4 are treated by the process according to the invention as follows: the printed product stream containing the printed products 4 is supplied in a uniform and uniform stream to the distribution conveyor 2 in which the printed product stream is divided transversely to the product stream 15 in the same direction as the original products 4a and 4 a print product stream containing printed matter 4. Each split print product stream is controlled by its own folding unit 20, where the printed products 4a and 4b are separately folded twice and further directed separately by the star wheel 6. . via the discharge conveyor 7 to a uniform product stream 4c ,;; with a flow rate substantially equal to the flow rate of the original product '·' · stream 4. In product stream 4c, the original printing products are folded twice their original condition.

It will be apparent to one skilled in the art that the invention is not limited to the above embodiment, but may vary within the scope of the claims set forth below. Thus, the solution according to the invention is not limited only to the apparatus described above which has a rack conveyor 1; . followed by a dispensing conveyor 2, followed by a folding apparatus 10, a sprocket 6, and a discharge conveyor 7. For example, the grab conveyor 1 may be replaced by any other apparatus desirous of donating to deliver a "uniform and uniform flow of printed matter 4 to 7 113357 and hand over shared product streams for further processing. Similarly, distributed product streams do not necessarily have to be parallel but may also overlap. In addition, the guide rails 18a and 18b need not be on the underside of the delivery conveyor 2 5 all the way, but it is sufficient that the guide rails are constructed so as to guide the trolley carriages 17a and 17b to the same centerline after delivery of the printed matter. Similarly, on the upper surface of the distribution conveyor at the beginning of the distribution conveyor it is advantageous to have widenings at the beginning of the guide rails 10a 18a and 18b so that the guide rollers 24a and 24b of the catching carriages 17a and 17b are reliably guided.
