4. One end of the suction tube 14 opens into the inner space of the core 3, and the other end communicates with a negative pressure source, such as a vacuum pump (not shown).

The aperture pattern imparting device 2 includes at least two apertures 13 as constituent elements. The aperture 13
indicates the vertical pleat folding process of the wrapping paper cylindrical body b, which will be described later, at the location where the vertical pleats of the wrapping paper cylindrical body b are to be folded, that is, at the location corresponding to the location where the vertical pleat folding applicator 1 is arranged. It is arranged so that it occupies a position facing the longitudinal central axis of the band c' at a location corresponding to the outer side of the neck of the band c', and is folded by an appropriate means, for example, by folding the longitudinal folds of the wrapping paper cylindrical body b. By attaching the throttle 13 to the tip of the plunger 15a of the air cylinder/plunger device 15, which is arranged at a predetermined position opposite to each other with respect to the vertical center axis of the zone c', it is possible to It moves in a convergent manner towards the neck of c' and returns to the position before the convergent movement. The diaphragm 13 can be a rod having a bifurcated shape from the front.

The pleating process of the head of the container/wrapping paper in the illustrated embodiment of the apparatus of the present invention is as follows.

The wrapping paper to be treated is placed in the 8th container in the cylindrical container a.
It is wound in the state shown in the figure, and at least a part of the overlapping part of the windings is glued. The winding and adhesion treatment may be performed by any suitable method known per se.

Container a wrapped with this wrapping paper is container a
The vertical pleat and crease applicator 1 is placed in a suitable manner, for example by a conveyor system known per se, with the head side facing the side of the longitudinal pleat and crease applicator 1.
The object is brought to the fixed position of the pedestal 16 and placed on the pedestal 16. When this container a is brought in, the vertical pleat folding device 1 occupies a place away from the container head a' to the right in Figures 1 and 3, where the core 3 does not hit the brought-in container a. It has been retreated to a position corresponding to The container a placed on the pedestal 16 is held between this and the pedestal 16 by a presser (not shown) from above. The container a held between the pedestal 16 and the presser foot is aligned with the core 3 of the vertical pleat applicator 1 in accordance with a predetermined design.

Next, the vertical pleat and fold applicator 1 is driven toward the container a by the air cylinder plunger device 6, and the core 3 in the vertical pleat and fold applicator 1 is driven by the forward motion accompanying this drive. It enters the space between the container head a' and the zone c of the wrapping paper tube b wrapped around the container a, which covers the container head a'. When this approach reaches a suitable degree, the vertical pleat applicator 1 is stopped. The start of driving of the vertical pleat applicator 1 may be controlled by an appropriate means, for example, by detecting the bringing of the container a into the pedestal 16 using an optical sensor, and based on the detection.

When the core 3 enters the space, the presser roller 4 and the presser rod 5 occupy positions corresponding to the outer side of the zone c of the wrapping paper tube b.
When the core 3 stops advancing, the presser rollers 4 and the presser rods 5 occupy positions facing the outside of the zone c of the wrapping paper tube b.

When the entry of the core 3 is completed, the lever 12 is rotated in a predetermined direction by the air cylinder/plunger device 9 using the slide block 10 as a working medium, and the presser rod 5 and the presser roller 4 are moved toward the outside of the zone c. The rollers move convergently from the location facing the core 3 toward the center of the circular arrangement of the presser rollers 4. With this convergent movement, the presser rod 5 presses the portion corresponding to the core valley 8 of the zone c against the core valley 8, and the presser roller 4 meshes with the core valley 8. Then, the portion corresponding to the core valley part 8 of the band c is pressed against the core valley part 8. When the band c is pressed by the presser roller 4, it is preferable that the presser rod 5 is already pressing a predetermined portion of the band c against the core valley portion 8. To do this, in the position before the convergent movement,
The presser rod 5 may be arranged with respect to the presser roller 4 so that the presser rod 5 occupies a position closer to the core 3 than the presser roller 4. In this case, the presser rod 5 is flexible (spring-like elasticity). When pressing band c under such specifications, pressing is performed first by presser rod 5, followed by pressing by presser roller 4, and the following vertical pleating process is performed for band c. is carried out effectively.

When the above operations are completed, the presser rod 5 and the presser roller 4 have moved in a convergent manner relative to the core 3, that is, remain in the closed state, and the vertical pleat folding device 1 is moved in the opposite direction to that described above. Accordingly, the presser rod 5 and the presser roller 4 are retracted together with the core 3.

Thus, the zone c of the wrapping paper tube b is pressed against the core valley portion 8 by the presser rod 5 and the presser roller 4, and due to the backward movement of the presser rod 5, the presser roller 4, and the core 3. , a vertical pleating process, that is, a pleating process, is performed to form a vertically pleating and forming band c'.

In this way, the pleat drawing process of the zone c is carried out in combination with the presser roller 4 and the presser rod 5 which is adjacent to the roller in the axial direction of the core 3 and extends along the core valley 8. The pleats are drawn in the zone c without causing any wrinkles or damage other than the pleats.
Also, during this pleat drawing, negative pressure is applied to the interior of the core 3 through the suction pipe 14, and negative pressure is also applied to the interior of zone c through the interior of the core 3. This makes it easier for the band c to form, which improves the results of the pleat drawing process in band c.

The front end of the core 3 (the left end in Figures 1 and 3) is the aperture 13
When the above-mentioned pleat drawing process proceeds until it retreats from the corresponding location to the right in FIGS. 1 and 3, the air cylinder plunger device is then moved while supporting the container a with the pleat-drawn wrapping paper on the pedestal 16. 15, the diaphragm 13 is moved from a location corresponding to the outside of the neck of the vertically fluted zone c' of the wrapping paper tube b toward the longitudinal central axis of the zone c'. Thus, the diaphragm 13 is applied to the neck of the vertically folded zone c' of the wrapping paper tube b which is supported on the pedestal 16, in other words, at the location where the vertically folded and grooved area is to be treated.
is moved in a convergent manner, and the vertically folded groove c' in the region facing the aperture 13 is narrowed from the periphery by the aperture 13, and the groove e is narrowed to the neck of the band.
is added.

In accordance with a predetermined design, this narrowing and sagging process is carried out in such a way that the front end of the core 3 is still in the zone c', and the zone c' is under negative pressure through the inner space of the core 3. Leave it behind. Therefore, the narrowing down patterning is effectively performed.

The wrapping paper cylindrical body b on the container a may be subjected to a folding process at the bottom part d by a conventional method at an appropriate point until the above-mentioned crimp process is completed.

After the above-mentioned pleat drawing process, the presser roller 4 and the presser rod 5 are returned to the state before the convergent movement, that is, the state in which they are opened relative to the core 3, by the air cylinder plunger device 9. The negative pressure load on the suction pipe 14 may be released at an appropriate time after the pleat drawing process.

After the above-mentioned squeezing process, the diaphragm 13 is returned to the position before the convergent movement by the air cylinder/plunger device 15, and the container with the wrapping paper that has been subjected to the pleat drawing process and the squeegee process is transferred from the pedestal 16 to the next position. It is discharged outside the system in preparation for the new folding process of the container and wrapping paper head.

Effects of the Invention As described above, according to the present invention, the container and wrapping paper can be subjected to the crimp treatment on the head part of the container and wrapping paper using mechanical force, and can be done without causing any wrinkles or damage other than the creasing process. A head pleat diaphragm can be provided.

Further, in the present invention, after the head of the container wrapping paper is creased, the neck of the vertically creased band of the wrapping paper is creased. In order to facilitate edge folding or other subsequent processing, the narrowing and sagging process allows the longitudinal pleats and creases applied to the required regions of the container and packaging paper tube to be maintained for a long period of time.

Furthermore, in the present invention, the vertical pleats and creases are applied to a predetermined zone by a vertical pleat and crease applicator, and the neck of the longitudinally folded and ribbed zone of the cylindrical container and packaging paper is located at the point where the creases are applied. Since it is possible to carry out the narrowing and texturing process using the narrowing and texturing device for the paper while the container/wrapping paper tube remains in place at the location where the vertical pleat and texturing process is to be performed, the latter process can be carried out at the end of the former process or immediately after the end of the former process. It is therefore possible to carry out a treatment, thereby making the latter treatment effective and achieving a longer retention of the longitudinal folds by means of the latter treatment.
