    The invention relates to a folding machine for role-playing rotary machines for manufacturing products that have been folded in the longitudinal direction, as well as in the transverse and longitudinal directions.
    A folding apparatus for products folded optionally in the longitudinal direction and in the transverse and longitudinal directions is known (accepted German application No. 2640110, class B 21 F 13/62, published on March 16, 1978).
    Products folded in the transverse and longitudinal directions are manufactured in a known manner by passing the web folded in the longitudinal direction through a group of combined mortise, knife and collective cylinders and one folding cylinder. These products are laid out by following the folding cylinder following the fold out cylinder. For the manufacture of products folded only in the longitudinal direction, another knife should be placed in the cutting cylinder, respectively, in the middle between the two knives, equipped with a number of gratescale or grippers. In the collecting cylinder, the folding knives should be replaced with cutting slots or deactivated if used together with the cutting groove. In addition, on the folding cylinder, respectively, in the middle between the folding valves, a row of grafts or grippers should be embedded, and the recoil point of rows of grates of Jivi grips of the collecting cylinder should be moved to the plane of the axes of the collecting and folding cylinders. Products folded in the longitudinal direction are alternately laid out on the folding cylinder folding cylinder and on the feather spreading device located under the collecting and cutting cylinders.
    A disadvantage of the known folding apparatus is that switching to another product due to the said replacement work to adjustment is associated with a large amount of time, which leads to prolonged machine downtime. In addition, when regulating the control of
    3. An apparatus according to claim 1, characterized in that the additional pen dispenser 7 has means for disconnecting it from the graphed-collecting cylinder 4 and outputting it to the outlet tape-belt conveyor 8 from the bed.
    Grapheads or grippers have the danger of tweaking, unless protective measures are involved that are costly. Inaccurate adjustment of graphek or grippers leads to unreliable functioning of the folding machine. Further, the product wiring is unreliable due to the fact that the graphed rows of the cutting cylinder are combined with knives. The knife holders raise the start of the product,
    so that at higher cylinder speeds, the product may rise from the graphets due to the air overpressure. The disadvantage is that the products, folded in the longitudinal direction, are displayed on two feather tips,
    Because of this, compared with the output of the products in one place, more maintenance personnel is required, and finally, the placement of the drive of the sewing cylinder in an oil-sealed design for other products is associated with significant technical costs.
    Also known folding apparatus for products, folded in the longitudinal direction and in the longitudinal and transverse directions (laid out the application of Germany
    No. 2517000, class In 65 N 45/16, published. 10.28.76). Products with longitudinal and transverse seam are made in a known manner from a web, folded in the longitudinal direction, by means of cutting, knife and valve cylinders.
    Folding machine. The products are laid out through a perforator on the outlet conveyor belt or from the valve cylinder of the folder by means of the conveyor belts are fed to the longitudinal folding device. For the manufacture of products, folded only in the longitudinal direction, under the knife cylinder there is a sharply-collective cylinder, which has three knives, each of which is equipped with a graphite row. Further
    the knife is removed from the cutting cylinder, the folding blades of the knife cylinder are replaced with cutting grooves or, if the blades are supplied with cutting grooves, the blades are turned off, the folding valves are not
    the valve cylinder is stopped, the graph rows are located and the recoil point of the grapheate rows of the knife cylinder is changed. Products folded in the longitudinal direction are assembled through the conveyor belts fed to the longitudinal folding device. Products folded in the longitudinal direction are output without selection from the cutting-collecting cylinder to the outlet conveyor belt. In order to do this, a series of graph sets must be stopped on the rim-knife cylinder.
    The disadvantage of this folding machine is that the changeover to other products is associated with a large investment of time. Due to the combination of graphene rows with knives, the wiring of the product is unreliable.
    Inaccurate adjustment of graphics control leads to functional malfunctions. Equipping the folding device with devices for the second transverse fold, in which the valve cylinder is very compacted, can lead to insufficient stability of the device operation at high speeds. In addition, the size of the area does not allow placing the threaded cylinder with the drive in a pressure-tight version for other products.
    The aim of the invention is the manufacture of a folding apparatus, having high functional reliability, requiring few service personnel, characterized by minimal merely when switching to other products and releasing products, folded both in the longitudinal, and in the transverse and longitudinal directions. In addition, in the case of differing products, it must be possible to economically operate the opening cylinder.
    The invention is based on the task of changing the folding unit for role-playing rotational machines with knife and slot-collecting cylinders, and a valve cylinder, in which the knife cylinder has one or several circumferentially at the same distance knives, which work together with located at the same distance along the circumference of the slot-collecting cylinder and provided with each row of graphs of marzans, the slot-collecting cylinder along the circumference in the middle between the marzans has Beside the folding knife working together with one of several folding valves located at the same distance around the valve cylinder cylinder, there is a pen switch with output taped conveyor for outputting products behind the cylinder cylinder so that it can be used to manufacture products.

    folded longitudinally in the transverse and longitudinal directions. The folding machine is distinguished by its stability, reliably conducts production and always removes it at only one recoil point. A quick and simple changeover of the folding device with a small number of replaceable elements is possible. In addition, the folding machine, while ensuring the sealing of drive oil
    0 cylinder wheels for different products made it possible to use a sewing cylinder.
    According to the invention, the marzans of the groove cylinder can be replaced by knives and grafted rows can optionally be put into action, the blade cylinder is additionally circumferentially opposite to the knife or in the middle between the knives has, respectively, one equipped with a graphical row of marq and can be rotated by the angle formed by the knife and the neighboring marzan respectively of its drive, and it corresponds to a graphee-collecting cylinder, which, along the circumference, has m spur
    5 by a row and by one squeegee of marzans, the distance between which is equal to the distance from the knife to the neighboring marzan on the circumference of the knife cylinder, the number of which differs by one from the sum of L1 marzans and knife blades of the knife cylinder and is equal in
     at least three An additional pen vykladyvatel with a lead-through tape conveyor is placed after the graphed collecting cylinder. Due to this, the folding machine can simply be re-adjusted to other products. To retool for the manufacture of products folded only in the longitudinal direction, it is only necessary to replace the marzans of the groove-collecting cylinder with the knife holders, turn off the graphene rows of the last cylinder and turn on the graphene rows of the knife cylinder, and turn the blade cylinder relative to its drive to 90 °.
    Work is carried out quickly, which causes minimal machine downtime.
     Adjustment is not required, the quality of which would affect the reliability of the folding machine. In the presence of devices for the second transverse seam, the valve cylinder is stable and works reliably at high revolutions. The graphed rows are not combined with the holder of the holder, and thus reliably conduct the products. Products are always laid out only through one pen spreader, due to which the need for maintenance personnel is reduced. And, finally, the spatial arrangement of the grapher-collecting cylinder and the pen spreading device allows supplying the slot-collecting cylinder
    oil-driven sewing cylinder for other products.
    Conversion to other products with a sewing cylinder can be made quickly if the grapheel-collecting cylinder, when the coupling connecting the cylinder to its drive pin is disconnected, together with another pen spreader and outlet tape conveyor or another pen sheeter when it is disconnected. together with the collecting-collecting cylinder together with the discharge tape-conveyor is retractable from the bed of the folding apparatus.
    FIG. 1 schematically shows a folding apparatus; in fig. 2 - products folding apparatus, folded in the longitudinal and transverse directions; folding apparatus; in fig. 3-longitudinally folded production; in fig. 4 is a view A of FIG. one; in fig. 5 is a diagram of a folding apparatus with a non-rising grapheel-collecting cylinder; in fig. 6 is a section BB in FIG. one.
    The folding device contains located one behind the other — knife 1, groove-collective 2, valve 3 cylinders, and also a graphite-collective cylinder 4 located on the knife cylinder 1. To output the product, after the valve cylinder 3 there is a feather reamer 5 with an output tape clamp the conveyor 6 and behind the graphee-collecting cylinder 4 - a feather vykladyvatel 7 with a lead-through tape conveyor 8. For making the products folded in the longitudinal and transverse directions of the product (Fig. 2) the knife cylinder 1 has two but 9, and the distance between them corresponds to the length of the wheelhouse. The knives 9 operate with three Marzan 11, evenly distributed around the circumference of the slot-collecting cylinder, each of which is combined with one graphite row 10 respectively. In the middle between the Marzan 11 there is respectively one folding knife 12, which interacts respectively with one folding valve 13 of the valve cylinder 3 Further, the valve cylinder 3 has three recesses 14 for knives 19 inserted instead of marzan 11 in slot-collecting cylinder 2.
    If required, three folding knives 15 can be conveniently placed on the valve cylinder 3 so that a second transverse fold can be produced with another valve cylinder (not shown).
    The production of a product folded in the longitudinal and transverse directions (FIG. 2) is carried out in a known manner from a folded paper folded along a folding hopper.

    The width 16 of the web in the printing machine during the passage of the knife, groove-collecting and valve cylinders 1 - 3. The products are output through the pen picker 5 to the outlet conveyor belt 6.
    In order to manufacture products that were folded only along (Fig. 3), on the knife cylinder 1 in the middle between the knives 9, two graphic rows 17 must be put into operation and the grooved rows 10 of the slot-collecting cylinder 2 put out of action. This can be done for example, connecting and, respectively, disconnecting the control of grapheme levers or, with only minor technical expenses, due to the fact that the pads are unscrewed from the graphee levers of the slot-collecting cylinder 2 and transported in the required amount afeechnye levers blade cylinder 1.
    The graphee rows 17 of the knife cylinder 1 are combined each with one marzan 18. Next, the marzans 11 of the slot-collecting cylinder 2 must be replaced with knives 19 and rotate the knife cylinder 1 by 90 ° relative to its drive. The latter is made very simple if, for example, the body of the blade cylinder 1 is rotatably mounted on its drive shaft and with the latter is in the drive connection by means of a finger coupling. Then there is a graphery-collecting cylinder 4 having three marzan 20, the distance between which is equal to the distance from knife 9 to neighboring marzan 18 on the circumference of knife cylinder 1. Each marzan 20 is combined with one grapherique row 21 and squeegee 22.
    FIG. The 1 blade cylinder 1 is rotated to a position for manufacturing products folded in the longitudinal direction. A paper web of half the web width In a printing press, by means of a folding hopper, it is folded one quarter of the web width, which corresponds to the required product width. The folded web 23 is held between the blade and slot-collecting cylinders 1 and 2, and is cut by knives 19 into sheets of length L. Each sheet is graphed by row 17 and is held by the blade cylinder 1. Upon reaching the plate-collecting cylinder 4, the beginning of the sheet is transferred to the graph box p house 17 into a graphee row 21. A sheet held by the grapheel-collecting cylinder 4 is divided in half with a knife 9 in conjunction with marzan 20. After this, the second half of the sheet is taken graphee row 21. The seamstress along the grafterer by means of a cylinder 4, the products are brought out by means of a pen rykladyvatel 7 on the outlet conveyor belt 8. By returning only every second graphite
    A number of 21 last is output with a selection. Recoil is supported by a squeegee 22.
    The number of pages of output may be increased if several webs are inserted into the folding machine overlapping each other. Production can also be made that is folded in the longitudinal direction, with a width of half of the web, if the folded web enters the folder with this width.
    In the folding machine for different products, an extension of the sewing cylinder 24 is possible, the drive of which is of the oil-sealed version (Fig. 6). To do this, it is first necessary to remove the collecting-collective cylinder 4 together with the feather spreader 7 and the outlet tape-belt conveyor 8 from the folding apparatus.
    In the embodiment of the device, these nodes, after the coupling 25 is disconnected, which connects the graphed-collecting cylinder 4 with its drive trunnion, are extended in the form of a cassette (Fig. 4). If the grapheera-collecting cylinder 4 is located higher on the knife cylinder 1, then
    it is enough to push out the stand reamer 7 and the outlet tape conveyor 8 (FIG. 5) from the stand. To do this, first disconnect the chain drive 26 between the cylinder-collecting cylinder 4 and the feather spreader 7.
    When retooling for the manufacture of products, folded in the longitudinal direction, rotation of the knife cylinder 1 relative to its drive is not required if you rearrange the knives 9 of the knife cylinder 1 and insert marzan 18 in their place. In this case, the grafted rows 17 must be placed on the original the location of the knives 9. This version of the retooling is associated, however, with increased costs in relation to installation.
    In an embodiment of the device, the blade cylinder 1 has two knives 9, but can, for example, also be equipped with one knife and one marzan opposite to it. The circumference of the knife cylinder is equal to the length “of the wheelhouse L.
    It is recognized as an invention according to the results of the examination carried out by the Office for the Invention of the German Democratic Republic.
