Description

  The present invention relates to a method for manufacturing a bag with a hand strap.

If a hole is made in the front and rear walls of the bag and the hand strap is passed through, there is a risk of tearing from the hole portion. Bags are often formed from this base paper for bags.
As a method for forming such a hand-drawn string body, an adhesive is applied to one side of a continuously fed belt and is transferred along a cylinder, and the string continuously fed to the adhesive application surface is staggered. While swirling, the adhesive is applied from the upper surface of the string, and another band is stacked, and these three members are bonded by pressing between the cylinder and the pressing roll, and then the adhesive is divided into two from the center and 2 A method of cutting the divided adhesive in a direction perpendicular to the flow direction is known (see Patent Document 1).

However, the hand strap string formed by this method is pressed from both sides by the cylinder and the press roller when the strap is pressed, so that both the two pieces of paper are raised at the strap portion, The space between the strings is depressed.
When such a hand strap is pasted on the bag base paper, the depressed portion of the paper piece is lifted from the bag base paper, resulting in poor adhesion, and when the article is stored in the bag, the hand strap string is caused by its weight. There is a worry that I can take it.

Japanese Patent Publication No.49-23035

  The problem to be solved by the present invention is that one of the two pieces of paper sandwiching the hand strap is formed smoothly, and the hand portion is removed from the bag by sticking the smooth piece of paper to the bag base paper. An object of the present invention is to provide a method for manufacturing a bag with a hand-drawn string that is easy to maintain by preventing the take-off and positioning a pressure roll for application above the belt.

  In the method for manufacturing a bag with a hand strap according to the present invention, a continuous strap is meandered on a first strip having an adhesive applied to the upper surface, and the curved top portions on both sides thereof are both sides of the first strip. After the second belt is stacked on the second belt via an adhesive, the first belt, the string and the second belt are pressed with a pressure roll from above the second belt. By bonding the band 2 and then cutting the adhesive along the center line, the left and right strips separated by cutting are cut to appropriate lengths on both sides of the curved top of the string. , A handbag portion formed by sandwiching a curved handbag string between a first paper piece formed from the first band and a second paper piece formed from the second band, and the first of the handpieces A piece of paper is affixed to the base paper for the bag, and is fitted on the surface of the pressure roll on the portion where the string is disposed. The relief grooves are formed, when pressurized with pressurizing roll, characterized in that fitting the disposed portion of the cord in the relief groove.

According to the present invention, when the pressure roll rotates and pressurizes from above the second band, the string arrangement portion is fitted into the relief groove of the pressure roll, so that the pressure applied to the string arrangement portion is other than As a result, the second band is raised at the portion where the string is arranged, but the first band remains smooth, and as a result, the first band is cut and formed. When the first piece of paper is pasted on the base paper for bag, it can be securely adhered in a wide area without a gap between the base paper for bag and the hand holding portion, and the hand holding portion can be prevented from being removed.
Furthermore, since the pressure roll for sticking is located above the band, it can be easily touched from the outside, and the maintenance is facilitated.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 6, the bag 1 with a hand strap manufactured by this invention has the bag main body 2, and the hand-holding part 3 with which the front-and-back wall inner surface of the upper-end opening part was each mounted | worn.
The handbag 3 is formed by sandwiching both ends of a handbag string 6 that is curved by a first paper piece 4 and a second paper piece 5, and the first paper piece 4 is attached to the bag body 2.

The hand-held part 3 is manufactured as follows.
As shown in FIG. 1, the first band 7 wound around the roll is guided by the guide roll 10 and sent out onto the lower roll 8 via a gluing device (not shown). In the gluing device, an adhesive is applied to the upper surface of the first band 7.
A string 6 ′ made of paper or synthetic resin is wound around a roll, continuously fed onto the first strip 7, and superimposed on the upper surface of the first strip 7 on the lower roll 8. It is done.

A plurality of string guide protrusions 9 are provided on the upstream side in the vicinity of the lower roll 8. The string guide device 9 has a substantially semicircular shape, and the arcuate side surfaces are alternately arranged in opposite directions.
Further, these string guide devices 9 are alternately moved in the opposite direction of the width direction so as to intersect the conveying direction of the first band 7 in the direction of the arc-shaped side surface, Move in parallel.
Then, it reaches both sides of the first strip 7 just before the lower roll 8, and then descends to deviate from the transport path of the first strip 7 and returns to the original position.

These string guide projections 9 approach the lower roll 8 while hooking the continuously fed string 6 'on the upstream side of the lower roll 8 with its arcuate side surfaces and alternately moving sideways in the opposite direction. .
Accordingly, the string 6 ′ is superimposed on the first strip 7 in a meandering state, and the curved top portion of the string 6 ′ protrudes on both sides of the first strip 7.
Further, the second band 11 wound around the roll is guided by the guide roll 10 ′, and further overlapped on the string 6 ′ stacked on the first band 7 through the gluing device 20. The second band 11 has the same width as the first band 7, and an adhesive is applied to the lower surface of the second band 11 in the gluing device 20.

A sticking pressure roll 12 is installed above the lower roll 8. The pressure roll 12 presses the laminated first band 7, the string 6 ′ and the second band 11 from above the second band 11, and cooperates with the lower roll 8 to form the first band 7. , The string 6 'and the second strip 11 are bonded.
Further, a plurality of escape grooves 13 are formed on the surface of the pressure roll 12 at a position that matches the portion where the string 6 ′ is disposed.
Since the portion sandwiched between the strips 7 and 11 of the meandering string 6 is slightly inclined with respect to the width direction of the strips 7 and 11, each escape groove 13 has an inclination angle of the corresponding string 6 ′. Correspondingly, it is formed on the pressure roll 12 with a slight inclination with respect to its axial direction.

Moreover, the depth of the escape groove 13 is formed slightly shallower than the diameter of the string 6 ′. Then, when the pressure roll 8 rotates and pressurizes from above the second strip 11, the portion where the string 6 'is installed is fitted into the escape groove 13 as shown in FIG.
Since the depth of the escape groove 13 is slightly shallower than the diameter of the string 6 ′, the portion fitted into the escape groove 13 is also pressurized, and the string 6 ′ is bonded to the first band 7 and the second band 11. However, since the pressure applied to this portion is very weak compared to the pressure applied to the other portions, the second strip 11 is raised at the portion of the cord 6 'and the space between the raised portions is depressed. The first strip 7 is kept in a smooth state.

As shown in FIG. 3, the adhesive obtained by laminating the first band 7, the string 6 ′, and the second band 11 passes through a slitter roll 14 installed downstream of the lower roll 8 and the pressure roll 12. To do. A blade 15 is attached to the central portion of the outer peripheral surface of the slitter roll 14 along the circumferential direction, and the adhesive is cut along the center line by the blade 15.
The left and right strips 16 and 16 ′ cut and separated by the blade 15 are respectively guided by a plurality of guide rolls 17 and fed into the cutting device 18.
As shown in FIG. 4, the strips 16, 16 ′ sent to the cutting device 18 are appropriately cut at both sides of the curved top of the cord 6 ′, and the cut cord 6 ′ becomes the hand strap 6. The first paper strip 4 to the first paper strip 4 and the second paper strip 11 to the second paper strip 5 are formed, and the hand-held portion 3 is obtained.

The handbag 3 thus obtained is transferred to the next step, and the first paper piece 4 is attached to the bag base paper 19 as shown in FIG.
Since the first paper piece 4 formed from the smooth first belt 7 is flat and has no depressed portion, it is securely bonded to the bag base paper 19 in a wide area.
The bag base paper 19 to which the handbag 3 is attached is formed into a handbag string-attached bag 1 having an arbitrary shape in a bag making machine.

Note that a plurality of sets of lower rolls 8 and pressure rolls 12 may be installed along the transport direction of the laminated first band 7, string 6 ′, and second band 11.
Further, the device for meandering the string 6 is not limited to that of the above embodiment, and a crank device or the like that reciprocates left and right by guiding the string 6 can also be used.
