Definitions

  • the object of the invention is therefore to provide a parallelepipedic packing of the type described at the outset, with which the creation of a sufficiently large head space on the one hand, an air inlet space at the rear end of the cut or the line on the other hand and finally and mainly avoiding the too high one Starting point is made possible so that the pouring jet can actually run precisely guided over the front tip of the pouring spout and its adjacent edges.
  • the cutting line is provided through the later separating cut between two pack blanks running one behind the other.
  • the knife is provided so as to protrude through a recess in a movable wiper that is resiliently biased towards the roller. It is very useful to design the perforation line as a straight line or as two straight lines separated by an inflection point.
  • Such knives can be easily manufactured and precisely held, e.g. B. by pinching. So that the packaging material to be processed can be easily removed from the knife after the cut, the scraper is attached, the recess of which encompasses the knife outline to a relatively narrow extent, so that a precise introduction of the cut and detachment of the paper from the knife are possible.
  • the area of the triangular top to be torn off increases because the longitudinal sealing seam can also be used as a gripping surface.
  • the double perforation line must be designed so that one half is arranged on one side and the other on the other side of the blank. The distance between them is bridged in the device for producing the opening means by the connecting tab.
  • the wipers can then again be arranged, the recess of which is close to the knife and as small as possible, so that the paper is held in a defined manner and the cutting depth can be set exactly.
  • a roller guide 34 with a recess 35 located therein is fastened to a roller guide carrier 33 below the plane with the carrier material web 18, here called the paper plane for short.
  • the stationary roller guide 34 one can see the three sections of the recess 35, namely the horizontal middle section 35a and the lifting sections 35b, which are set on the outside at an angle downward from the knife 25.
  • the ball bearing 36 of the shaft 37 of the roller 31 is guided in this recess 35.
  • the lower paper guide 37 ′′ is placed on the stationary roller guide 34 in the form of an externally folded sheet, in which a recess 38 is provided, through which the roller 31 can reach as it moves along the movement according to the double arrow 38 ′.
  • FIG. 3 is viewed, which is a schematic and partially broken view of the top view of FIG. 1 along the section line 111-111, the direction of view for the lower part of FIG. 1 means the view of FIG. 3 from below in the direction of FIG Paper run, which is also indicated in Figure 3 with the arrow 19.
  • the recess 46 is also in to see the stripper 39 movably pressing onto the surface of the carrier material 18 (resiliently pretensioned). This recess 46 lies relatively close to the cutting edge 32 lying under the knife parts 27 and 28, ie close to the knife 25 with a small area, so that the paper web 18 is held in a defined manner and the cutting depth can be exactly aligned.
