Definitions

the invention relates to a folding apparatus with a puncture and folding knife cylinder having cutting strips and grooved bars, on which a cutting cylinder equipped with knives is employed, and a folding jaw cylinder arranged downstream of the puncturing and folding knife cylinder.
stoppers or other accumulations of paper or a paper jam can occur in particular between the puncture and folding knife cylinder and the folding jaw cylinder since, for example, the printed copies which are cut on the puncturing and folding knife cylinder and held only by punctures or needles can be loosened, one loosened copy can be torn away by subsequent copies, which leads to a jam or a paper accumulation in the gap between the folding jaw cylinder and the puncture and folding knife cylinder, which, as explained above, can lead to damage. Turning the sheets over can also cause such problems. To avoid the aforementioned dangers, it is also generally known to pivot a cylinder when stoppers or paper jams occur, so that the gap between the puncture and folding knife cylinder and folding jaw cylinder becomes sufficiently large. However, monitoring and pivoting a cylinder is relatively complex and the response time is also relatively long.
the object of the present invention is to avoid the dangers or consequences of stoppers or a paper jam using simple and inexpensive means.
This object is achieved in that pits or flattenings are provided between adjacent folding jaws of the folding jaw cylinder, each extending in the axial direction of the folding jaw cylinder, in such a way that when the gap (center A) is rolled over, a cutting bar or a grooved bar of a pit or a flattening is provided opposite.
It is advantageous to cover the pits or flats by means of elastic elements which are preferably arranged next to one another. These elements can be made from spring band steel or from a suitable elastic plastic.
the puncture and folding knife cylinders are usually provided or equipped with a diameter adjustment that is guided in eccentrically mounted bolts, these segments can yield in the event of a paper jam in the center between the jaw cylinder and the puncturing and folding knife cylinders.
a stable construction is required due to the function of the grooved bar.
the grooved bar must provide an abutment or a support for the cutting bar if a sheet is cut in the cutting cylinder with the aid of the cutting knife.
the folding apparatus 1 shown in FIG. 1 is supplied with a printing material web 2 via pulling rollers 3, 4 in the usual way.
the printing material web 2 comes between a cutting cylinder 5 and a puncturing and folding knife cylinder 6.
the cutting cylinder 5 has two opposite knives 7 here.
the puncture and folding knife cylinder 6 is equipped on its periphery with several cutting strips 8 and punctures 9.
grippers can also be used within the scope of the invention, in order to grasp the beginning of the supplied printing material web 2 each before a specimen is cut between a knife 7 and a cutting bar 8.
specimens are guided over a corresponding circumferential area of the puncturing and folding knife cylinder 6, after which, with the aid of the folding knife 10 of the puncturing and folding knife cylinder 6, the folding takes place, in which the folding knife 10 is on the Puncture and folding knife cylinder 6 encounter specimens lying in jaws 13 of the adjacent or subordinate jaw cylinder 12.
the folded ones Specimens then arrive in the usual way along an arrow 15 into a paddle wheel 14 and from there onto a ribbon cable 16.
the pits 18 or the flats 20 can be provided with elastic cover elements 19, 21, for example in the form of adjacent elements made of spring band steel or of a suitable elastic plastic, so that the pits 18 or flats 20 extending in the longitudinal direction of the jaw cylinder 12 are virtually bridged.
the parts 13, 18, 19 which are present in triplicate were only provided once in FIG. 1 with reference numerals for reasons of space.
the length of the pits 18 or the flats 20 seen in the circumferential direction of the jaw cylinder 12 can be determined by experiments or the longest possible circumferential section between two adjacent jaws 13 can be used to produce the pits 18, as is the case for the embodiment according to FIG 4 is the case. This ensures that any stoppers or accumulations of paper that occur in any case can pass through the gap between the cylinders 6, 12 without any risk of damage occurring.
