Definitions

  • the present invention relates to a method for timing a film web, preferably in a cold foil stamping process, in which the film web is moved in accordance with a law of motion through a transfer nip.
  • the transfer gap is formed by a transfer cylinder and an impression cylinder and the law of motion of the film web describes at least temporarily deviations from a synchronous movement of the film web relative to the transfer cylinder.
  • the film web is braked at least temporarily, so that film material can be saved.
  • the invention relates to a device for transferring a transfer layer from a transfer film to a printing substrate, said device comprising a transfer nip formed by a transfer cylinder and an impression cylinder and through which the transfer film is guided by means of guide elements.
  • timing elements are provided for the film-saving timing of the transfer film in the transfer nip.
  • the invention also relates to a printing press, in which a device according to the invention is provided, as well as a computer program product, which is able to perform a corresponding method.
  • a disk for storing a corresponding computer program product is affected.
  • Generic film transfer devices are used in the refinement of printed products, for example, to produce gloss effects.
  • the machines can be subdivided into hot stamping foil machines and cold foil stamping machines.
  • the transfer layer is transferred to the sheet material, ie to a printing material such as a sheet only under pressure, but not additionally under the action of heat.
  • a printing material such as a sheet only under pressure, but not additionally under the action of heat.
  • adhesive is printed so that a printed image of adhesive remains on the sheet, which can subtract a corresponding transfer layer from the transfer film used within a film transfer station, so that this Transfer layer in sections on the sheet adheres.
  • the transfer layer can be partially transferred in the transfer nip under the action of pressure substantially in the regions applied with adhesive.
  • the problem with this film transfer technique is that the transfer film must be moved at the same speed as the substrate during the transfer and that usually only small areas on the substrate to be covered with the transfer layer.
  • a transfer cylinder involved in the transfer nip often has a so-called channel in which a blanket can be fastened. In the area of this channel no transfer can take place by means of pressure from the transfer layer. Therefore, should always be regulated so that the substrate dips into the transfer gap between the transfer cylinder and a counter-pressure cylinder when the channel can not be in the range of the printing material.
  • Other areas where transfer film is transported unused through the transfer nip are areas in which no transfer layer is to be transferred onto the substrate.
  • the transfer film For better use of the transfer film and to reduce consumables, it is z. B. according to the EP 932501 B1 provided to move the transfer film over a pair of dancer rollers, which move cyclically in common with the channel of the transfer cylinder, so that the transfer film is braked in the region of the channel to a speed of zero, for example.
  • the two dancer rollers are coupled together so that transfer film web, which is stored by the still moving supply roll from a first front dancer, is released by a second rear dancer simultaneously to the collecting roller. In this way, a certain constancy of the web tension can be ensured in the storage and collecting role.
  • both dancers are moved coupled in a braking direction.
  • the film can also be withdrawn from the transfer nip.
  • the problem may arise that the film tension varies, which occurs in particular when in the region of the transfer cylinder a channel, for example.
  • a gripper of the impression cylinder is provided for clamping a blanket and / or for Dipping a gripper of the impression cylinder is provided.
  • the transfer film is then at least once in contact with a gap beginning, in which the film tension drops first and then in contact with the gap beginning, where the film tension increases sharply by the sudden train.
  • it is in the DE10 2009 020 106 A1 proposed to move the dancers of the dancer system asymmetrically to each other so that the voltage changes of the transfer film is counteracted by corresponding opposite relative movements of the dancers to each other.
  • the object of the present invention is to propose a method for timing a film web, which allows a simpler structure of the law of motion, whereby the law of motion can be adapted faster and possibly also easily to given, possibly changing boundary conditions.
  • the object of the invention relates to an apparatus for carrying out this method, a printing machine with such a device, a Computer program product for implementing the method and to propose a data carrier for storing this computer program.
  • the motion law is constructed in sections of sections of elementary functions.
  • elementary functions are generally to be understood as those functions that can be represented by an analytical expression. These include the rational functions, the trigonometric functions and their inverse functions, the exponential and logarithm functions, the hyperbolic functions and their inverse functions as well as those which can be represented as the sum, difference, product or quotient of the functions mentioned.
  • Such simple elementary functions are particularly preferred here as are the trigonometric functions, in particular the cosine and sine functions, but also the e-functions or their products or sums.
  • the sections of the elementary functions must have an identical pitch in their respective points of contact and essentially describe the speed of the transfer cylinder in the areas which adjoin the synchronous operation to the transfer cylinder. Only by this voltage changes of the transfer ribbon voltage can be avoided or at least limited to a minimum.
  • the sections of the elementary functions in their sum extend over a portion of a period of the transfer cylinder.
  • One period of the transfer cylinder describes within a printing machine when it is z. B. is a blanket cylinder, the area in which a multiple or a single print image is transferred to a substrate.
  • the transfer cylinder runs synchronously with any blanket cylinders present in the different inking units of the printing press. Within this period of the transfer cylinder, there are then areas or sections in which no transfer layer is transferred from the transfer film to the printing substrate. Does the transfer cylinder a channel area, z. B. for clamping a blanket, so at least this channel region is excluded for the transfer of a transfer layer. The beginning of the channel region then describes the end of printing and the end of the channel region then a further pressure start, in particular also with respect to the transfer of the transfer layer.
  • the size of the portion over which the portions of the elementary functions extend in their sum be less than or equal to a section in which no transfer layer is transferred to the substrate.
  • the size of this portion can also be adjusted by an operator, in particular during a running transfer process.
  • a particularly preferred subselection of the elementary functions are the symmetric functions.
  • the sections of the symmetrical functions in particular brake and acceleration distances can be constructed symmetrically within the law of motion in an analogous manner. This is especially true for the sine and cosine functions.
  • symmetrical functions are preferably selected whose initial and final pitch essentially correspond to the synchronous operation of the transfer film with the transfer cylinder.
  • a normalized amplitude ie a slope of 1
  • a particularly simple possibility of adjusting the law of motion to different desired savings or sizes of the proportion of a period of the transfer cylinder always results when, advantageously, the different sections are always used by the same elementary function, the elementary function being an elementary function, which extends over the entire portion of the period of the transfer cylinder in which no transfer layer is transferred.
  • This may advantageously be just a sine or cosine function, the zero crossings of the complete period coincides with the beginning and end of the proportion of the period of the transfer cylinder.
  • the savings potential of the timing of the transfer film is substantially predetermined. Changes that occur during the printing process, such as: B. could be the case with digital printing, can not be reacted with a change in the saving on the fly or with a change in the proportion with respect to a period of the transfer cylinder. Also, it is not possible for the user to vary the savings should he find that the desired result is not achieved by the machine.
  • the possibilities according to the invention for quality defects within the clocking or for the use of digital printing methods arise for the user changing non-printing areas to respond.
  • a control device may automatically recognize how the areas not to be transferred change, and in this way automatically calculate the length of the respective sections as a function of the desired saving and the sections of the elementary function redefined on the fly and adapted to the changes in the digital artwork.
  • a clocking with changing artwork in a digital printing arrangement is possible in which the proportions change with respect to a period of the transfer cylinder. This adaptation can be done on the fly in particular.
  • the law of motion can be easily adapted to parameter changes without having to deposit curves and without having to use an interpolation method.
  • This adaptation is not computationally intensive, so that it can easily be carried out during operation.
  • Self-contained protection is also claimed for a generic device according to claim 8, which provides control of the timing elements that drives the timing elements so that the law of motion of the transfer film is built according to the method described.
  • the control of the timing elements should preferably be connected to a control device of the printing press and particularly preferably input elements for input of the requirements from the amount desired saving, share of sections of the elementary functions in their sum of one period of the transfer cylinder and angular velocity of the transfer cylinder.
  • independent protection is claimed on a printing machine, which includes a corresponding device, as well as on a computer program product, which brings the inventive method on a computer for execution, as well as on a data carrier, which stores the corresponding computer program product.

  • the collecting roller 8 is on a friction shaft which is driven faster than the rear advantage.
