Definitions

  • the invention relates to a method for producing a Foil sheet for a folding pack, such as as Flowpack is known.
  • the folding pack consists of this sheet-like material.
  • the invention also relates to an apparatus for performing this method.
  • a folding pack made from such a film web is used to pack freeze-dried items, for example Coffee, biscuits or other stimulants, the air and moisture proof respectively should be packed aroma-tight.
  • a folding pack is known from EP-A-0 432 028, which not from two separate but from a single one Can produce film web. To do this, the film web is longitudinal separated. The resulting two parts of the track should then brought into a partially overlapping position become. Details, such as the overlapping process exact alignment of the two web parts also in the longitudinal direction the film web can not be ensured made.
  • the invention is based on this prior art the task of specifying a possibility with which the above disadvantages can be avoided and in particular to specify a film web for a folding pack, where a sample drawing is always exactly available.
  • This invention is according to the manufacturing process Claim 1 and by the device according to claim 7 given. Useful further training of the procedure or the device for performing the method are the subject of subclaims.
  • the essence of the invention lies in the special overlap technique with several specially arranged and aligned Deflection rollers that manufacture the film web for a folding pack of the type mentioned at the beginning with a exact transverse and longitudinal offset of one on the folding pack existing sample drawing from a single sheet of film allows.
  • the deflection rollers are used to cut them open inevitably two web parts created from the film web brought into the desired exact overlapped position, in who then put them back together, such as glued together can be.
  • Redirecting at least one of the two web parts is carried out with at least two rollers with their axes of rotation parallel to each other and parallel to Level of the track are arranged, the axes of rotation of the Rolling at an angle other than 90 degrees to the transport direction are aligned.
  • This Detour route can be so with a repeating pattern long be chosen that the relative length of the detour this part of the track to the other part of the track an integer multiple the length of a repeating pattern. This can ensure that in the overlapped web area repetitive, across the entire width of the Path "right" patterns can arise.
  • both can also be separated Train parts go through separate detours. To this Way, there can be a relative length difference between the two Path parts are avoided, so that the same pattern with cutting the web, and then cut can be composed identically again.
  • the not existing length offset includes a reduced Material waste at the beginning and end of the roller conveyor, as both Track parts without longitudinal misalignment at the beginning and end of the track are available for their further use.
  • the overlap width that is the lateral offset of the two Path parts to each other, and the mutual longitudinal offset of the two web parts can be changed by changing the angular position the axes of rotation of the rollers to the longitudinal direction of the Train and by varying the length of the respective detour route to be changed.
  • the length of the detour route leaves easily change, for example, that the middle roller is relative to the other two rollers can take different positions. So the middle one
  • the height of the roller for example, can be varied, i.e. in Transversely to the plane of the web adjustable become.
  • a kind of knife can be used to cut the web against the web be judged. It is also possible to use a roller-shaped one To arrange the cutting edge.
  • the roller-shaped cutting edge can Be part of a roller roller lying against the web.
