DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the cigarette bundle pack shown in FIGS. 1 and 2 are formed in two pack rows 12, 13, and are used for the outer packaging of (laminated) paper, foil or thin cardboard. It has ten cigarette packs 10 surrounded by members. The cigarette pack 10 has a large-area side surface, ie, a front side surface and a rear side surface facing each other. In the area of the central longitudinal face of the package unit, a continuous separating surface 14 extends between the two pack rows 12,13.

The outer wrapping member 11 comprises a front wall 15, a rear wall 16 opposed thereto, elongated side walls 17, 18 provided therebetween, and end walls 19, 20 also provided opposite each other. Is provided.

The side wall 18 is provided with a folding tab on which a portion of the outer wrapping member overlaps, ie, the outer wrapping member edge strips 21,23. This outer edge strip 2
1 has a width greater than the width of the inner edge strip 23. The outer edge strip 21 extends completely across the entire width of the side wall 18, while the inner edge strip 2
3 has a width (slightly) smaller than half the width of the side wall 18. The free end of the edge strip 23 thus ends at a distance from the separating surface 14.

The two edge strips 21, 23 are connected to one another in the area of the overlap 24, ie glued or sealed together. The overlapping portion 24 includes the cigarette pack 1
9 with a width slightly smaller than the width of the associated (end) face. The overlap 24 is off-center, i.e. in the area of the side wall 18, to one side, i.e. the separating surface 1.
Extend to the side adjacent to 4.

The present exemplary embodiment relates to a plurality of bundles of tobacco packs 10 of the hinged type. These packs are arranged with the lid facing the side wall 18 (FIG. 2).
reference).

The end walls 19, 20 have a plurality of folding tabs, namely trapezoidal and triangular inner flaps 22 and top flaps 25 (FIG. 3). Top flap 25
Is formed in a rectangular shape and completely covers the end walls 19, 20 as outer flaps. For this purpose, the top flap 2
5 is separated from the adjacent inner edge strip 23 by a perforation line 27.

In the area of the long side wall 18, an opening aid is provided. This opening aid is a line of weakness that can be easily torn, i.e. a perforated line 27 in the area of the outer wrapping member 11. This perforation line 27
It extends approximately in the middle, ie, along the (imaginary) longitudinal centerline of the side wall 18. This perforation line 27
It extends substantially the entire length of the side wall 18 and terminates a small distance from the end wall 20 of the upright pack.

The perforation line 27 is mechanically, that is,
During the manufacturing process of the bundle pack, that is, the blank for the outer wrapping material 11 is applied in the material web to be manufactured.

For this purpose, a web 29 drawn from a reel (not shown) is guided through a perforating unit 30. Following this, a blank with perforations 27 is cut from the material web 29. This blank is further processed in the packaging machine to form the outer packaging member 11.

FIGS. 4 to 8 show a special drilling unit 30.
Details are shown. The whole device is EP 0 854
098 may be assembled.

A particular aspect of the drilling unit is a drilling blade 64 used as a drilling tool. It has a sawtooth cutter with a plurality of triangular blade tips 65. The cutting edges 66 of the blade tip 65 are arranged at an angle to each other, and both side surfaces are sharpened. The cutting edges are arranged at an acute angle to one another.

Each blade tip 65 is punched and cut as a continuous perforated line 27 in a material web or blank. The length of the punch cut is determined by the penetration depth of the blade tip 65. Thus, the piercing blade 64 is moved toward the material during the working stroke to create a continuous row of stamped cuts. The movement of the piercing blade 64 is therefore
In particular, it is limited by a limiting stopper. The length of the perforation blade 64 matches the length of the perforation line 27.

The piercing blade 64 is provided with the piercing unit 3.
It is attached to a mount mechanism that moves up and down within 0, that is, moves up and down with respect to the lifting carriage 67. The lifting carriage 67 is provided below the surface of the material web 29. The piercing blade 64 with the upwardly directed blade tip 65 is thus moved, in particular from above, by the upward movement of the lifting carriage 67 from below.
Moved to The lifting carriage 67 can slide along the lateral guide rod 68. A small stroke biasing cylinder 69 with a non-rotating piston (not shown) is employed to bias the lifting carriage 67 and the piercing blade 64. The biasing cylinder 69 is provided below the lifting carriage 67 and shares the center with the lifting carriage 67.

The piercing blade 64 is fixed to the upper surface of the elongate lifting carriage 67. The piercing blade 64 having a relatively thin wall structure is seated in one rod-shaped mount, that is, in the long support 70.
The piercing blade 64 projects from the top of the support 70. The support 70 is lifted in return for the carriage 6.
7 and is fixed to the lifting carriage 67 by fixing bolts 71. Since the anchor bolts are seated in bore holes 72 having a large diameter, the relative position of the piercing blade 64 or the support 70 can be changed in the longitudinal direction of the lifting carriage 67.

The lifting carriage 67 or the urging cylinder 69 is located on the base 73 (lower side) and is releasably connected to the machine frame. The biasing cylinder 69 is supported in an adjustable manner, that is, supported by an adjustment bolt 74 in a concave portion located substantially at the center of the base portion 73. This adjustment bolt 74
Can be adjusted under the base 73 with the aid of a suitable tool and an adjusting screw 75. The penetration depth of the piercing blade 64 in the material web 29 is:
An adjusting screw 75 and an adjusting bolt 7 are provided via a biasing cylinder 69 which performs a lifting movement which is firmly fixed in advance.
4 can be set.

Guide rod 6 for lifting carriage 67
8 is similarly fixed to the surface of the base portion 73.

During the piercing cut, the material web 29 or blank is held in place by the piercing blades 64, and in particular by the piercing blades 64, which are sandwiched between clamping members having a large area. Said clamping member comprises, on the one hand, a lower clamp plate 76 below the material web 29 and an opposing clamp plate 77 opposite or above the material web 29 and facing the clamp plate 76. The opposing clamp plate 77 is fixedly connected to the guide rod 68.
The (lower) clamp plate 76 can be moved up and down. The piercing cut is performed by pressing the web of material 29 against the lower surface of the opposing clamping member 77 by the upward movement of the clamping plate 76 in the area of the piercing blade 64.

The clamp plate 76 is provided with the drilling blade 6.
4 and is mounted on the surface of the lifting carriage 67 for the purpose of this vertical movement. During the upward movement of the lifting carriage, the clamp plate 76 is first pressed against the material web 29 or the clamp plate 77,
Thereafter, while the lifting carriage 67 further continuously moves up, the perforation blade 64 further moves up to the position shown in FIG. 5 or 7 to perform perforation cutting.
It is connected to the lifting carriage 67 in an elastically movable manner.

For this purpose, the clamping plate 76 is lifted by a lifting bearing 67 by means of a load bearing bolt 78.
Connected to. This load bearing bolt 78 is freely seated in a borehole of the lifting carriage 67. The clamp plate 76 is supported by a spring 79 in an elastically free manner. A helical spring 79 surrounds each load bearing bolt 78. During the upward movement of the lifting carriage 67, these springs 79 are pressed to the upper end position where the lifting carriage 67 can reach (right side in FIG. 5).

The material web 2 where the piercing blade 64 is running
9 or to make a perforated cut freely in the blank,
The clamp plate 76 has a slit 80 extending in its longitudinal direction, through which the perforated blade 64 or blade tip 65 penetrates. On the opposite side, the opposing clamping plate 77 is provided with an elongated groove 81 extending in its longitudinal direction, into which an area of the blade tip 65 passing through the material web 29 can enter.

The punching unit 30 having such a structure
After passing through the web of material 29-similar to the exemplary embodiment of Fig. 3-is fed by winding the deflecting rollers 82 of the pendulum 32. On the opposite side (outlet side) there is another diverting roller 83, which supplies the material web 29 (with perforation 27) to the cutting unit 31.
