Definitions

  • the invention relates to a machine for manufacturing and / or processing a material web, in particular Paper or cardboard web, according to the generic term of claim 1 and a method for transfer a threading strip or a material web with their entire width within one machine for the production and / or processing of the material web according to the preamble of claim 7.
  • a machine is used to solve this task the features of claim 1 proposed.
  • This comprises at least one recording device a recording head, preferably as a suction head trained and can be acted upon with a negative pressure through which the threading strip or the material web can be led out of the web path is.
  • the structure and function of the reception facility and especially the recording head WO 98/56701, the content of which is the subject this description is made.
  • the machine further comprises at least one treatment device for the material web, at least has two functional elements, between which the Material web can be passed, especially during the normal operation of the machine.
  • the machine is particularly characterized in that with the help of a displacement device a relative movement between a first functional element and a second functional element can be implemented is what creates such a large gap between the functional elements is formed so that the recording head, the at least partially in the railway path protrudes, can be passed through.
  • This is in advantageously a safe threading of the threading strip or the material web with of their entire width, even at high running speeds the material web, possible.
  • the relative movement between the functional elements can be realized in that only one of the functional elements is moved while the other maintains a fixed position. Furthermore is it is possible that both functional elements shift be, the movements preferably such are controlled or regulated that the Functional elements towards each other or move away from each other. Furthermore, the relative movement in that the rate of displacement and / or route of one Functional elements is larger than that of the other Functional elements. Opening the nips between the Functional elements is also possible in that both functional elements in one and the same direction be shifted, the shift speeds are chosen such that the -in Seen direction of movement - subsequent functional element falls behind.
  • the movements of the functional elements can basically at the same time or take place successively, the rate of displacement the functional elements must be the same can. To relocate the functional elements preferably hydraulic, electrical and / or mechanical Funds used.
  • the treatment or processing device comprises at least one calender, a coating device with preferably at least an application device for the coating substance, a drying device, a printing unit and / or another auxiliary device.
  • the smoothing unit or the coating device can have two or comprise more than two rollers, which during the Normal operation of the machine at least one too form the nip called nip. The nip is closed between the rollers, so what the web of material passed between the rollers coated and / or smoothed accordingly becomes.
  • the "normal operation" of the machine Operating phase referred to in which none or at least no significant interference in that Manufacturing and / or processing sequence of the material web occur.
  • the order setup of a Coating device can be, for example, a nozzle applicator or roller applicator with subordinate Doctor elements, brushes or the like include the normal operation of the machine with the Material web in contact or in one only short distance to a support roller as a rule guided material web are arranged.
  • the Drying device for the treatment of the web after coating or to dry the Material web itself is provided, such be formed that the material web only treated on one side or on both sides, that is, is dried. For this, for example a gas flow onto the material web surface directed or upset. Further it is possible to use the web of material respectively the coating applied to it with the help of Radiant heat or other suitable drying systems to dry.
  • the printing unit is used for printing the material web with graphics or text.
  • the treatment facility can also have an impregnation device, for example for textiles.
  • the auxiliary device can Example of a device for electrostatic Unload the material web or an embossing device for the material web.
  • a method is also proposed to solve the problem, having the features of claim 7. It is provided that by a relative movement between a first functional element and a space between a second functional element formed or a between the functional elements existing space can be enlarged as much, that the recording head can be passed through. To a tear off of the material web or at start-up the machine will have a distance between the functional elements of the treatment facility made a passing of the at least partially recording head protruding into the web path the recording device allows.
  • the relative movement immediately before Passing the pick-up head through the space between the functional elements can, for example, with functional elements, which are heated can be prevented from cooling.
  • the functional element or the Functional elements in his / her operating position will be relocated after the recording head has passed the functional elements.
  • the duration of the spacing of the functional elements be reduced to a minimum.
  • the functional elements only in their operational position will be relocated if through the entire width of the material web the treatment facility or between passed through the at least two functional elements or through the manufacturing machine and / or processing of the material web is performed.
  • An embodiment of the method is also preferred, which is characterized in that the relative movement to form a sufficiently large one Space between the functional elements gradually, preferably depending on the transfer speed the threading strip / the material web.
  • This is particularly so in one embodiment of the treatment device, in which this has at least one heating device has, advantageous because of the relatively slow Opening the nip between the functional elements or enlarging the space between the functional elements these of the in the space between the functional elements Do not cool incoming fresh air as quickly.
  • the relative movement of the Functional elements for closing the gap (nip) or reducing the space in Steps, making an adjustment of the functional elements to the changed operating state possible is.
  • the relative movement between the functional elements takes place in an advantageous embodiment depending on the transfer speed of the Threading strip / the material web, which from the The web path is passed out into the pick-up head and dissipated through this, preferably suctioned off, becomes.
  • the transfer speed is preferred smaller, in particular significantly smaller than the running speed of the material web during of the transfer process.
  • the machine described below is general for the production and / or processing of a material web applicable.
  • the web of material can Example a paper, cardboard, textile web, plastic film, Be fleece, non-woven.
  • Under construction the material web is, for example, in Connection with a paper web a finishing, such as coating or smoothing Roger that. Drying is also under processing understood the web.
  • the invention is everywhere applicable where previously not with a special Transfer system was worked.
  • Figure 1A shows a section of a machine 1 for the manufacture and / or processing of a figure 1 material web, not shown, namely a cross section through an embodiment a treatment device 3, the first Functional element 5 and a second functional element 7 includes.
  • the first functional element 5 is from a deflection compensation roller 9 is formed, a rigid crossbeam, also known as a yoke 11 and a sleeve-shaped roller jacket 13 has, which the cross member 11 in the area of Covered path of the material web.
  • the outside diameter of the cross member 11 is smaller than that Diameter of the through opening of the roll shell 13, whereby an annular space 15 is formed.
