Definitions

  • the invention relates to a device for marginal trimming a material web, which is fed in a longitudinal direction, comprising at least one longitudinal cutting knife, by means of which the material web in the longitudinal direction in a partial web and an edge strip is severed, a discharge device for discharging the generated edge strip and a longitudinal cutting blade in Longitudinal downstream cross-cutting blade with a cutting blade for cutting the edge strip transverse to the longitudinal direction, which is independently activated by the longitudinal cutting blade.
  • the invention also encompasses a method for edge trimming of a material web which is fed in a longitudinal direction, wherein the material web is severed to form at least one incision in the longitudinal direction in a partial web and at least one edge strip, wherein the longitudinally leading end of the edge strip transversely to Cut longitudinally and subsequently the generated edge strip is removed.
  • Such devices and methods are known and are used, for example, for edge trimming of a material web in the form of a plastic film web, which are produced continuously by known methods and is supplied in a longitudinal direction.
  • the edge trimming of such a material web is customary to produce a clean edge region of the material web and to eliminate, for example, width variations thereof.
  • the margins are produced by a longitudinal continuous cut, it is necessary at the beginning of the cutting process to see the leading edge of the marginal strip, i. the region in which the longitudinal cutting blade has first occurred in the material web for severing the same, to cut across the longitudinal direction L, since in this region of the edge strip is firmly connected to the rest of the material web.
  • edge strip In general, such is done in a cross-sectional longitudinal direction by hand, whereupon the separated edge strip is also fed by hand to the discharge device.
  • the cutting of edge strips with a hand knife or by tearing off by hand involves a high security risk.
  • the object of the invention is therefore to propose a device and a method of the type mentioned, which allow a reliable and secure transverse separation of the edge strip even at high web speeds of the supplied material web in a particularly simple and inexpensive design.
  • transverse separation is understood to mean a severing of the edge strip transversely to the longitudinal direction of the material web fed in.
  • the device according to the invention is distinguished by the fact that the cross-cutting blade adjacent to the cutting blade has a separating device which, when the cross-cutting blade is activated, enters the cut produced by the longitudinal cutting blade in the material web.
  • the position of the at least one longitudinal cutting blade is transversely to the longitudinal direction of the material web variable and accordingly, the position of the separating device is adjusted accordingly to always ensure the reliable entry of the separating device in the generated incision.
  • the separating device comprises a protruding over the cutting blade pin, which is particularly easy to manufacture.
  • the cutting blade may be jagged according to a proposal of the invention to increase its cutting performance and wear resistance.
  • the discharge device may comprise a suction nozzle for sucking the edge strip according to a proposal of the invention.
  • the transverse separating knife it is preferable for the transverse separating knife to be arranged adjacent to the inlet opening of the suction nozzle, more preferably the transverse separating knife is arranged at the rear edge region of the inlet opening, so that the material web fed in the longitudinal direction runs onto the transverse cutting knife in the region of the edge strip and is forcibly removed , in which the edge strip accumulates in front of the cross-cutting blade and is reliably detected by the action of the suction nozzle.
  • the cross-cutting blade is arranged extendable on the suction nozzle.
  • the cross-cut knife can also be e.g. be arranged pivotably on the device by means of a pivoting lever and, if necessary, e.g. be moved by means of a hand lever or via a corresponding drive in a cutting position in which it cuts through the edge strip transverse to the longitudinal direction.
  • Characteristic of the cutting behavior of the cross-cutting blade and so far for the method according to the invention for edge trimming of the web is that before separating transversely to the longitudinal direction of the edge strip, the separating device is inserted into the recess and the edge strip separated from the sub-web. Only after inserting the separating device in the incision, the transverse separation of the edge strip by means of the cross-cutting blade.
  • a material web 1 for example, a plastic film can be seen, which is continuously prepared by known methods, for example as blown or flat film and fed in a longitudinal direction L.
  • this is severed continuously by means of a longitudinal cutting knife 2, not shown, in the direction of the longitudinal axis L into a part web 10 and an edge strip 11.
  • the longitudinal cutting blade 2 in this case generates an incision 12, which at the same time forms the boundary between the partial web 10 and the edge strip 11.
  • the edge strip 11 thus produced has already been severed at its longitudinal end L end already transversely to the longitudinal direction L, so that it can be separated from the remaining part of the web 10 according to arrow A and removed. Especially at high feed rates of the material web 1 in the longitudinal direction L of this cross-cutting of the edge strip 11 special attention must be paid.
  • the longitudinal cutting blade 2 in the longitudinal direction L downstream not only provided a suction device 3 in the form of a suction nozzle 30 with inlet 300, which detects the separated edge strip 11 and sucks, so that it can be used again, but at the longitudinal direction L considered rear edge region of Inlet opening 300 is a transverse separator 4 is provided, which in more detail from the FIG. 3 can be seen and the working position based on the reference numeral 4 also from the FIG. 1 is apparent.
  • Characteristic of the cross-cutting blade 4 is that this as shown here at the left edge, which is associated with the recess 12, a projecting beyond the cutting blade 40 separating means 41 in the form of a pin, which prior to the cutting of the edge strip 11 by the cutting blade 40 at the one with E in FIG. 1 indicated point is inserted into the recess 12 and causes a separation of the edge strip 11 of the partial web 10, in which in the illustrated embodiment, the edge strip 11 on the right side and the partial web 10 are passed on the left side of the separating device 41.
  • the device and the method explained above are more suitable not only for edge trimming of plastic films but also for a variety of other material webs, such as paper, textile, nonwoven webs and the like.
