Definitions

  • the invention relates to a method for the transverse folding of webs and a folder to carry out the procedure.
  • a folder of the type mentioned is known. He has two separate fold groups for the transverse folding of printed copies, whereby the in the one folding group still held in jaws of a jaw cylinder Print copy with one fed from the other fold group via ribbon cables second printed copy is placed one on top of the other. That kind of Merging the two printed copies can lead to deviations, that is, the alignment of the two printed copies to one another is not always exact. Further the known folder has a relatively complex construction.
  • the invention is therefore based on the object of a method of the type mentioned Kind as well as to create a folder for performing the method, in which a exact product processing, especially a precise folding result with a simple one compact structure can take place.
  • the multiple flap of the Folding jaw cylinders are provided, in which, for example, a first, folded product is held and which - preferably after which the jaw cylinder a partial rotation has passed - the further product is fed for folding, whereby it - in Interaction with a folding knife cylinder - forming the fold of one adjacent jaw of the multiple flap is added.
  • This Merging can, for example, take place precisely at the leading edge. Deviations, as in the prior art due to serving as a transport device Band lines can occur when merging the products are at Subject of the invention avoided due to the multiple flap.
  • the construction of the The configuration according to the invention is simple and therefore inexpensive.
  • the jaw cylinder several folding knife cylinders are assigned to separate webs. If for example by means of the longitudinal cutting device mentioned from a former fed web two sub-webs are formed, so there are two separate webs before, each of which can be fed to a folding knife cylinder.
  • this Registration can be a folding knife cylinder or the folding knife cylinder at the same time also be designed as a point cylinder, that is, they are suitable from the to fix the respective web of separated products. This can be fixed with, for example Puncture needles are made. Alternatively, it is also possible that the fixation by means of grippers he follows.
  • the jaw cylinder assigned several, for example two, folding knife cylinders may be, it is possible that the respective separate Lanes (especially partial lanes) each with one Folding knife cylinders work together to separate products fed to the multiple flap. This is done in such a way that a first jaw of the multiple flap that of a first Folding knife cylinder receives upcoming product and that one another, second jaw of the multiple flap that of one other folding knife cylinder coming product jammed takes over.
  • the inclusion of the products can be done in different angular positions of the jaw cylinder respectively.
  • the arrangement of the folding knife cylinder different circumferential positions of the jaw cylinder leads to a space-saving design.
  • the folding jaw cylinder has several Gripper cylinder for the optional supply of the Products are assigned to different discharge routes. These gripper cylinders are also located on different ones Circumferential positions of the jaw cylinder. Preferably can the folding jaw cylinder two folding blade cylinders and two gripper cylinders can be assigned. Because several Gripper cylinders are available with a very high Speed can be worked because of the multiple there are no bottlenecks. With two Discharge paths due to two gripper cylinders - compared to a solution with only one discharge path - the double the time available, so for example the second Longitudinal fold without affecting the Production speed can be carried out. By the larger product distances can do the specimens better delayed and more secure.
  • At least one of the gripper cylinders can preferably be one Have folding knife arrangement that with the The jaw cylinder interacts.
  • the Folding knife arrangement it is possible for one product make further cross folds. An example comes from the Figure 5 and their description.
  • At least one of the discharge routes Longitudinal folding device is assigned. Depending on what you want Folded product can be folded here.
  • At least one of the gripper cylinders preferably points in this way trained or arranged grippers on that this only with one, in particular - in the direction of rotation of the Folding jaw cylinder seen - leading jaw or some jaws of the multiple flap cooperates.
  • this gripper does not work with all jaws Multiple flap together so that it is not all in the Multiple flap held products, but only part of it, that is, those in the Jaws are held with which the gripper cooperates.
  • the remaining products can later by another gripper cylinder.
  • the Multiple flap designed as a double rebate flap, that is, it has two jaws for independent of each other possible holding two products.
  • the Double rebate flap a cylinder-fixed (jaw cylinder fixed) clamping web, that is, this The clamping web is not movable, but stationary on Jaw cylinder arranged. With the front respectively On the back of the clamping bar, one clamping jaw works together, to create the two clamping options mentioned above Clamping jaw with the interposition of the product against one side of the clamping web, this is how the clamp seat is created; the other jaw kicks against the other Side of the clamping web, there is a pincer-like holding device for the other Product.
  • the process according to the invention consists of the following process steps:
  • the products are used for cross folding from a folding knife of a folding knife cylinder acted upon and clamped in the fold area to hold, while at the same time Clamping there is a transfer from the folding knife cylinder to a folding jaw cylinder, and wherein at least two products are merged in this way during the folding process and be held separately on the jaw cylinder so that they are in a desired relative position, in particular with congruent or approximately congruent fold edges are arranged adjacent to each other.
  • Figure 1 shows - in a schematic representation - one Folder 1, the one former and a means symbolically arranged longitudinal cutting device 3 having.
  • the Guide roller pair 6 is assigned a deflection roller 9.
  • two folding knife cylinders 10 and 11 are provided each with a cutting cylinder 12 or 13 work together.
  • Form the folding knife cylinders 10 and 11 also point cylinder.
  • a jaw cylinder 14 acts with the two folding knife cylinders 10 and 11 together and is also in active function with two gripper cylinders 15 and 16.
  • At least the gripper cylinder 15 is one Folded knife arrangement assigned so that it is one Cross-fold cylinder forms.
  • the gripper cylinders 15 and 16 close Discharge routes 17 and 18, respectively Longitudinal folding devices 19 and 20 are assigned.
  • a web 23 runs into the former 2 of the folder 1, For example, a paper web, one that by means of Folding former 2 longitudinally folded or by means of Slitter 3 in two separate tracks (Partial webs 24 and 25) divided and on the funnel is turned on each other.
  • the partial webs 24 and 25 become then products, preferably printed copies, by separation and folding. This will be discussed in the following discussed in more detail.
  • the jaw cylinder 14 has at least one, preferably several designed as multiple flaps 26 Folding flaps 27 and is also with usual, simple Folders 28 provided. The following will first focus on the received various folding products of Figures 2 to 5, which can be produced by means of the folder 1, among other things are.
