Definitions

  • the invention relates to a new adhesive tape and to processes for the flying roll change, for example in paper coating and / or printing presses using the new adhesive tape and the use of the new adhesive tape.
  • Paper spreading and printing machines used in finite paper rolls must, after demolition or after production stoppages of any kind, use the paper web mostly with the use of a so-called kite running on one side over the full width of the machine with the paper web to be fed, and on the other side with one through the entire machine Belt is connected to be listed.
  • kite running on one side over the full width of the machine with the paper web to be fed, and on the other side with one through the entire machine Belt is connected to be listed.
  • the introduction of a new paper web is extremely time-consuming and thus causes high costs in terms of downtime.
  • the new roll In an intended roll change, the new roll is set in the direction of flow in rotation until its peripheral speed is almost identical to the web speed of the running of the old roll paper web. Thus, the beginning of the new role does not flutter by the rotation, a conscientious fixation of this role start with the located under the roll start second layer of the new role is necessary.
  • the roll start of the new roll usually has an uncovered adhesive surface over the full machine width.
  • the paper web of the old roll is pressurized with the adhesive surface at the beginning of the new role brought into contact, whereby the expiring paper web of the old role is glued to the roll beginning of the new role.
  • EP-A-0 418 527 a method for the flying change is proposed especially in a rotary printing press, in which the fixation of the roll start with the underlying second layer of the new roll is to be effected by means of an applied over the entire roll width adhesive strip.
  • the adhesive strip is subdivided into three zones, of which the first zone is designed to be adhesive on at least one side and applied to the beginning of the roll of the new roll.
  • the second zone is not adhesive and is provided in the longitudinal direction with a perforation, the second zone comes to rest on the roller leading edge of the new role.
  • the third zone is again formed adhesive at least on one side and is glued adjacent to the roller leading edge on the uppermost layer of the new role.
  • the uncovered adhesive surface required for bonding to the draining paper web of the old roll is formed by forming the first or the third zone with double-sided adhesive or by applying it to the outer surface of the roll beginning from the adhesive-material adhesive strip.
  • numerous double-sided adhesive strips can also be applied to the new roll, running parallel to the unwinding direction.
  • the method thus described is in principle very effective, but has the disadvantage that when using an adhesive strip whose first and third zone is formed only one-sided adhesive, numerous operations are required, so that the process is time consuming and complicated. Especially with short roller running times, it can quickly happen that the time between two successive Rollenwechsein is not sufficient to prepare the adhesive surfaces. If, on the other hand, an adhesive strip is used whose first or third zone is adhesively bonded on both sides, the comparatively very high costs of such an individually produced, only partially double-sided adhesive strip are disadvantageous.
  • the solving during the flying reel change by breaking the Sol arthritisßpassage releasing the beginning of the roll with the underlying second layer of the new role is done by means of the first and second portions of the tape.
  • the gluing of the rotting start of the new roll with the running paper web of the old roll is done by means of the fourth section of the adhesive tape.
  • EP-A-1 076 026 proposes a completely different way of using an adhesive tape to carry out the flying reel change with integrated fixation of the reel start at the second position of the new reel located under the reel end.
  • the known double-sided adhesive tape is glued with its back over the entire width of the roll on the second layer of the new role that the front of the tape can be glued to the half of the back of the roll beginning of the new role to fix it.
  • the other half of the front side of the adhesive tape is glued to the running paper web of the old roll during the flying reel change.
  • the deciding factor in this proposal is the fact that the double-sided adhesive tape consists of two materials which are laminated together over the entire surface and whose lamination adhesion is lower than the adhesive force on both sides of the adhesive tape.
  • the lamination serves as a predetermined breaking zone of the splitting adhesive tape.
  • the CA 20 39 631 provides, inter alia, an adhesive tape having on its front side an adhesive layer, partly on the underside of the roll beginning of the new roll and in the course of the flying roll change partly on the running paper web of the old roll is to be stuck, and on its back has a double-sided adhesive tape which adheres on the one hand with great adhesive force on the outer layer of the new roll and on the other hand with low adhesive force on the back of the known adhesive tape.
  • the double-sided adhesive tape should guarantee a sufficient fixation of the roll beginning with the second layer of the new roll until this fixation tears at predetermined predetermined at the splice with the low adhesive force during the flying reel change.
  • an adhesive tape section for the flying role change of paper rolls which serves to fix the pointed cut paper web beginning of a roll to be loaded only about 5 to 10 cm wide tape portion is by two transversely extending slot lines that together approximately in the middle of the strip of adhesive tape, divided into two sections.
  • the one section starts from the trailing edge in the direction of the leading edge first over the entire width of the adhesive tape section and subsequently in the form of an isosceles triangle delimited by the two clipping lines, the other section extending from the front edge to the two transverse slot lines.
  • both sections, starting from the front or rear edge upper are subjected to the entire width with rectangular adhesive layers, with both adhesive layers being separated by a surface not applied with adhesive.
  • Both adhesive layers applied on the underside are covered by protective films.
  • On the upper side only the tapered section extending from the rear edge in the direction of the front edge is completely loaded with an adhesive layer, which is likewise covered with a protective film.
  • the adhesive tape section with its rear edge adjacent lower side adhesive layer is glued to the top of the pointed cut paper web start the roll to be loaded, that the edges of the pointed cut paper web start almost congruent with the transversely aligned, the tape portion in two sections dividing slot lines ,
  • the applied on the underside of the adhesive tape portion of the leading edge adhesive layer is bonded adjacent to the paper web leading edge with the uppermost layer of the roll.
  • the paper web of the roll to be loaded can be connected to the running web of the old roll by gluing the upper-side adhesive layer to the old roll.
  • the separation of the web fixing for the paper web start of the roll to be loaded is carried out by tearing the tape portion along the transverse slot lines.
  • an adhesive tape provided for flying rollover can have two regions separated by a perforation line, each of which carries a stretchable adhesive on the same side of the adhesive tape.
  • the distance between the front edge of the adhesive tape and the perforation line is selected to be smaller than the distance between the perforation line and the trailing edge of the adhesive tape, whereby the front region of the adhesive tape between its front edge and perforation line is narrower than the rear region of the adhesive tape between its perforation line and trailing edge , Due to the full-surface coverage of both areas with the adhesive, which in turn is completely covered by protective films, the handling of the known adhesive tape is difficult. In particular, when removing the protective film, which covers the adhesive on the wide rear area, there is a risk of tearing, which can lead to significant production disruptions due to the possible high time pressure in the flying role change.
  • the new adhesive tape in combination to ensure both the bonding of the roll start of a new roll with the running paper web of an old role as well as the fixation of the roll start with the underlying second layer of the new role.
  • the adhesive layer strips to be applied on the first side of the adhesive tape may be surface-opaque, screened or in whatever form patterned.
  • the two adhesive layer strips on the first side of the second region located between the trailing edge and the predetermined tear line together cover at least 75% or even more preferably at least 90% of the said first side of the above-defined region.

Same is It is possible that to the front edge and / or the predetermined tear line out a narrow, if necessary also interrupted running, non-adhesive trained auxiliary strip is provided, the easier handling of the adhesive tape according to the invention in particular when sticking his lying between leading edge and predetermined tear line area on one for the flying role change intended to serve new role.
  • both adhesive layers are separated on the first side of the second region located between the trailing edge and the tear line by a non-adhesive intermediate strip.
  • a non-adhesive intermediate strip it is possible that between the predetermined tear line and the adhesive tear strip adjacent to the predetermined tear line a narrow, if necessary interrupted, non-adhesive auxiliary strip is provided.
  • auxiliary strips and the intermediate strips are intended in particular to facilitate removal of protective films preferably to be provided on the third and / or fourth adhesive layer strips.
  • the first adhesive layer strip applied on the first side of the first region located between the front edge and the predetermined tear line is preferably not covered with a protective film, wherein at the same time the second side of the adhesive tape according to the invention is designed such that blocking of the rolled-up adhesive tape is precluded.
  • blocking in the sense of this invention is the bonding of the individual layers of the rolled-up adhesive tape to understand, in the rolled-up state each first and second side of the adhesive tape in contact.
  • the predetermined tear line divides the adhesive tape according to the invention in a ratio of 1/3 to 2/3, wherein the smaller first area between the leading edge and the predetermined tear line, corresponding to the larger second area between the trailing edge and the predetermined tear line, should arise.
  • the desired tear line separating the adhesive tape according to the invention into two regions can be formed as a perforation. It is equally possible to form the predetermined tear line as a fold line. Another embodiment provides to form the predetermined tear line as a line of spaced-apart straight cuts.
