Definitions

  • the proposed device relates to the zigzag folding of paper, fabric, film, plastic or the like.
  • existing webs with a back and forth swiveling consisting of at least two parts, interconnected by means of a joint, movable relative to each other, made of plates, sheets or the like.
  • Compound channel-like guide device for the web or webs to be folded the last part of the guide device in the running direction of the webs containing a pulling device consisting of revolving rollers for the web or webs to be folded in each case.
  • Devices of the aforementioned type are used on printing presses, in particular form printing presses.
  • the web printed, punched or otherwise processed in these machines is fed to a zigzag folding device and subsequently fed to a zigzag-folded stack or deposited into such a stack.
  • a web can be fed in devices of the type mentioned. It is also possible for a number of tracks lying one above the other to run through the machines mentioned. This is the case, for example, if a form consisting of several pages is to be produced.
  • only one web is referred to in the following even if it is a multi-layer web consisting of several individual webs lying on top of one another.
  • zigzag folders contain a multi-part guide channel for the web, which is used to guide the web back and forth so that it can snap off the perforations incorporated into the web and running transversely to the running direction of the web without the web for example, by "air turbulence.
  • Multi-part guiding devices for the web provide far better guidance of the web to be deposited than single-piece guiding devices.
  • DE-PS 1 070 010 Devices of the aforementioned type are known for example from DE-PS 1 070 010.
  • this device contains traction rollers, which are arranged at the lower end of the pivoting device or guide device for the web, viewed in the direction of travel of the web. With these traction rollers, the web is to be guided tightly through the swivel device in order to ensure that the web runs smoothly through the guide channels.
  • the arrangement of the pull rollers according to DE-PS 1 070 010 results in inertia forces which limit the maximum speed of the folding device in an undesirable manner.
  • inertial forces are generated on the parts of the guide channel that swing back and forth. At high running speeds, these inertial forces take on an order of magnitude that limit the running speed of the printing press and thus that of the web. This limitation can be, for example, such that the machine upstream of the folder must run below its maximum speed because of the downstream folder.
  • Another device is known for example from DE-PS 1 152 301. In the direction of the web to be folded, this device does not only contain pulling rollers at its lower end, but even a double set of these rollers, between which belts are stretched. This device also leads to inertial forces which assume an extent that the performance of the machine upstream of the folding device must be limited in an undesirable manner. Also in this prior publication it is pointed out (in particular column 1, line 19 to 27 and column 1, line 38 to column 2, line 35) that the run-up to the web against the side walls of the guide device can result in disruptions, which can cause the run of the hindered to fold web.
  • a device for zigzag folding of webs of paper or the like in which the lower part of the two-part guide device contains walls which serve to guide the web to be folded.
  • the lower pair of rollers of a pulling device arranged entirely in the upper part of the guide device is arranged in the vicinity of the joint connecting the two parts of the guide device, and there is an opening between the side walls of the lower part of the guide device and the aforementioned pair of rollers.
  • the inertial forces are significantly lower than in the case of a front direction according to DE-PS 1 070010. It has been found, however, that a smooth running of the web in the lower part of the guide device is not guaranteed.
  • the entry angle of the web in the exit-side guide part and the opening width remain unaffected by the pivot position.
  • the pulling device consisting of rollers is arranged in the vicinity of the swivel joint, which connects the last part of the guide device in the running direction with the part in front, at least the side walls of the last part of the guide device in the region of the rotating pulling rollers, at least one opening included and at least the parts of the side walls of the guide device which contact the surfaces of a web to be folded in each case are provided with a profile so that the guide device becomes light and air can be inserted between the side walls and the web to be folded.
  • the exemplary embodiment can be modified in various ways without departing from the framework defined by the basic idea of the invention.
  • the web is bent, for example, at point 2 with the aid of a striker 3 in the area of the transverse perforation and thereby forms a zigzag-shaped stack 4.
  • web 1 passes through a plurality of channel-like guiding devices arranged one behind the other in the running direction of the web, which form the different parts of a paper guiding channel .
  • the movement of these parts is made possible by connecting rods 5 and 6, which in turn are moved by driven eccentrics 7 and 8.
  • the two parts 9 and 10 of the guide device are connected to one another by a hinge 11 and are consequently pivotable relative to one another.
  • the first part 9 of the guide device in the running direction of the web 1 can also be pivoted about a further joint 12, which is located in the frame of the folding device.
  • the second joint 12 is thus stationary, while the first joint 11 is pivoted back and forth by the movement of the connecting rod 5.
  • the channel-like guide device is consequently composed of a total of several parts arranged one behind the other in the running direction of the web 1.
  • the second joint 12 contains a driven shaft 13 which is rotatably mounted in the frame 14 of the machine.
  • a pulley 15 is connected to the shaft 13, via which a belt (not shown) runs, which drives the second pulley 16.
  • the second pulley 16 is connected to a shaft 17, the geometric center of which corresponds to the pivot point of the joint 11.
  • a gear 18 is also connected to the shaft 17, which meshes with further gears 19 and 20.
  • the gears 19 and 20 are in turn connected to pull rollers 21 and 22.
  • the pull rollers 21 and 22 are rotatably mounted in the second and last part 10 of the guide device in the running direction of the web 1.
  • the pulling device for the web 1 consisting of the rollers 21 and 22 comes to lie in the immediate vicinity of the swivel joint 11 connecting the two parts 9 and 10 of the guiding device.
  • This distance 23 can be kept small, for example, by using the highest possible strength materials for the gears 18, 19 and 20.
  • the channel-like guiding device for the web 1 contains side walls 24, 25, 26 and 27, which are at least as wide as the web 1 to be folded. These side walls are connected to corresponding brackets 28 and 29, which are located on the first and on the second part of the guide device. These side walls generally consist of metal sheets which are welded or screwed to a guide channel to be passed through by the guideway 1. According to the present invention, sheets of aluminum or high-quality steel are preferred for this, so that these sheets can be made as light as possible but vibration-resistant. For example, so-called stainless steel can be used for this. These side walls are contacted by the web 1 to be folded when the channel travels and thus come into contact with the web at least temporarily.
  • these side walls In order to further increase the stability of these side walls, ie in order to be able to make the side walls as thin and light as possible, they are provided with a profile, which can consist, for example, of the corrugations 30 and 31. However, a different type of profiling than that shown in the figures is also possible.
  • the side walls are angled in the manner of nozzles, so that nozzles or windows are formed between the side walls of the individual parts of the guide device.
  • the side wall 24 is angled according to the angle ⁇ and the side wall 27 according to the angle ⁇ .
  • the window 32 that extends over the entire width of the web to be folded, for example, allows air to flow into the channel-like parts of the guide device and to slide between the side walls and the web 1 to be folded. This air travels with the web 1.
  • said windows can be prepared as shown in the embodiment in other ways, for example as' abandoning the angled portions of the side walls.
  • connecting rods 5 and 6 as well as the holders for the side walls 24, 25, 26 and 27, can be arranged on both longitudinal edges of the web to be folded. This essentially amounts to a symmetrical addition to the figures.
