Definitions

the product designed at production speed can be specially designed by adding aggregates to the folding line, which can be used, for example, to perforate, apply adhesive, number, impress, and other measures. Separate further processing outside of the printing and folding line is not necessary in most cases, because the application of the measures mentioned in the so-called in-line process delivers finished products.
the plow folder can be switched on along the existing web processing without complex web guiding means.
the sheet is cut to size transversely to the unwinding direction by means of the cutting cylinder arranged downstream of the former.
Format cuts of this type can also be carried out with the plano boom in the case of folded products that are equally thick across the width, that is to say have the same number of sheets left and right justified.
the plano boom which has a cross cutting device, is set up adjacent to the folder and is used when cross folding and gathering is not required.
both of the cutting devices mentioned are designed for cutting long or half-long sections. (The term long or half long refers to the circumferential value of the impression cylinder). Smaller section lengths require the use of a variable rotary cross cutter with several knives distributed over its circumference and running in the axial direction.
the adjustment of the knives and the high cutting frequency pose problems during operation.
the known arrangements have the disadvantage that the processing of multiple longitudinally folded products, which also have small useful lengths lying below the cylinder circumference, is very complex in the in-line method and is therefore also prone to failure.
the series connection of plow folding stations set up outside the folder in conjunction with a variable rotary cross cutter not only poses drive and web tension problems due to the elongated line, the high cycle frequency of the knives of the variable rotary cross cutter also requires the web or production speed to be reduced.
a prerequisite for the solution to be created is to attach it to existing equipment in the folder and to include it as much as possible. This is intended to increase the degree of utilization of the existing facilities and to ensure easy conversion or retrofitting between the types of production.
the two solutions created for this purpose which are reproduced in the characterizing part of the main claim and in the characterizing part of the secondary claim, are essentially based on integrating the plow folding stations required for the longitudinal folds in a compact manner in the superstructure of the folder and for cross-cutting into the part-length benefits propose two different cutting devices, only the first of which works on the web or the folding strand.
the second cutting device cuts the sections which are created in the first cutting device and are transversely brought into shingled stream formation to the final utility format.
the advantage of this arrangement consists mainly in the elimination of the variable rotary cross cutter and consequently in a production which is simplified with regard to the web processing and is no longer limited in speed by the high operating frequency of the rotary cross cutter.
the web processing is shortened and thus simplified.
Both the cutting device of the plano boom and the cutting cylinder associated with the folder can serve as the first cutting device.
the process depends on whether the production is with or without a former, i.e. Utilization of the longitudinal fold and / or cross fold possibility given by the former is to be used.
the transfer devices of the cylinders are expediently designed as punctures. Grippers would of course also be possible.
the folder which is also used for other productions, is of conventional design and is also suitable for collective production and delta fold attachment, on which, if necessary, can be converted to folding flaps by exchanging the punctures.
the printing web D After leaving the last printing unit and passing through the dryer, the printing web D is fed from the last cooling roller to the folding devices. Punching, perforating or gluing mechanism 29 or 30 can be switched on optionally.
each plow fold station of plow fold stations I, II, III and IV has an upper and lower plow folder 1,1 ', 2,2', 3,3 ', 4 , 4 '.
the undershot plow folder receives an apostrophe.
the plow is folded in in the direction of the imaginary line that is valid when the web is running straight, which in the exemplary embodiment is also longitudinal axis of symmetry 31 of the plow fold station.
the plow folds When viewed in the direction of web development, the plow folds are fastened at a distance from the longitudinal fold edges to be attached and, for the purpose of specifically adjusting the position of the fold edge, can be displaced and locked transversely to the direction of web development.
the longitudinal register stability is created by means of controllable register devices 6 which ensure that the web is cut into the web sections P in the correct position. As a rule, only the last register device 6 located in front of the respective cross-cutting device in the form of the cutting cylinder 12 or the knife cylinder 18 is acted upon. Since the tension web D is removed during the longitudinal folding, wherein any web wrapping is also associated with a loss of web tension, tension roller groups 7 ensure that the web tension is maintained intact.
the arrangement which is geared towards a practical number of longitudinal folds, has a total of 5 longitudinal folds, including 4 plow folding stations I, II, III and IV and a folding former 8. Preferably only a maximum of 4 longitudinal folders are loaded.
a procedure includes the series connection of all 4 plow fold I, II, III and IV.
the upstream connection of the P is flugfalzstationen I and II or III with a maximum provided in front of the former 8.
the plow fold station IV is located below the plow fold stations I, II and III.
the number of plow folding stations I, II, III and IV which can be connected upstream of the former 8 is limited by the ability of the fold strand, which becomes stiffer from fold to fold, to be unwound. (A drawing of the path from plow folding station IV to the infeed roller of the former is therefore not provided, although this path is generally possible.)
the first sequence which includes the former 8, runs over the folding cylinders of the folding unit 9, see also FIG. 2. This makes transverse folding possible.
the puncture cassettes are exchanged for folding jaw cassettes, and the puncture groove cylinder 10 is additionally equipped with folding knives.
the slowed down second tape line system 16 must be slowed down even more in order to bridge the gaps which arise during the transverse folding.
the folded printing web D is cut into web sections P with the knife cylinder 18 belonging to the cross-cutting device.
the number of cycles is only one cut per revolution, as is also the case with the cutting cylinder 12 of the folding unit 9.
a pair of traction rollers 19 literally drives the multiple-section web sections P into a conveying nip which is formed from a slowed down lower belt line and an upper belt line which has been driven at least web speed or higher, so that scale flow formation is formed.
the stream of shingled material which is still conveyed in the web unwinding direction, arrives in a corner conveyor 20 which rotates the longitudinal axis of the web sections P by 90 ° relative to the conveying direction.
the shingled stream formation is retained in the corner conveyor 20.
the distance from B to ahnabbaldkante web section edge can be changed according to the speed ratio of the mutually perpendicular strip lines, especially is added, that the web sections P in the corner conveyor 20 run lengthwise and widthwise and accordingly the scale distance also changes by the ratio of width to length of the web sections P.
the corner conveyor 20 which points to the entry of the rotary longitudinal cutter 23, in the direction of the stop edge 22 which forces the 90 ° change of direction, and by means of alignment, not shown here, such as so-called joggers, the web sections P in FIG rotated formation so precisely aligned that on the rotary slitter 23 sufficient cutting quality, ie Parallelism of edges is guaranteed.
the multiple uses N contained in a path section P are now present side by side. Their distance determines the lateral distance from the circular knife 24 to the circular knife 24, correspondingly also the lateral distance of the counter knives interacting with the circular knives 24.
a cut-out is made at the level of the dividing line.
two pairs of circular knives which cut out a narrow strip and are usually arranged more or less offset in the direction of transport are used.
a table-shaped rotary slitter 23 with a flat conveying surface can be used. Improved guiding properties can be achieved by a rotary longitudinal cutter 23 which, as shown in the exemplary embodiment, has a drum-shaped counter-knife device 25 and in which the web sections P pass through a curved conveying surface.
the curvature has the consequence that the web sections P are bent and thereby lie more rigidly and securely against slipping, on the other hand, the wrapping of the upper belt results in an additionally acting contact force which holds the web sections P on the counter knife device 25.
the circular knives 24, 24 ' are axially aligned with a sufficient distance from the cutting line to the cutting line. If the distance between the cutting lines is less than the width claimed by the suspension of the circular knives 24, 24 1 , the circular knives 24, 24 ′ which make adjacent cuts are arranged offset to one another. Such an arrangement is used when strip-shaped cutouts are made.
Counter knives and spacers for adjusting the cutting distances both with regard to the width of the panels N and the strip-shaped cutouts are drawn up as rings on the shaft of the drum-shaped counter knife device 25.
the circular knives 24.24 1 in the cutting groove preferably they are overfed, ie slightly higher peripheral speed in relation to the scale flow rate applied.
the belts or toothed belts run on a diameter which is smaller in relation to the outer diameter of the circular knives 24.24 1 .
the small sections originating from two center cuts or from two cutouts give the three benefits N obtainable from a web section P in the exemplary embodiment.
the panels N separated from the web section P are fed onto a delivery belt 28 for stacking.
the path section P can also be kept longer than the circumference of the cylinder. Any multiples of the useful length are conceivable for the cutting length of the path sections P.
the cutting cycle is to be set by means of suitable gear technology measures.
the folding former bypass is used.
