DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a hand-held string laminated with a plastic film used for bags and the like.

[0002]

2. Description of the Related Art Conventionally, a hand strap for a bag in which a vinyl chloride resin, a polyethylene resin, or the like is laminated on the surface of a non-woven fabric is manufactured by using a band-shaped material Z in which a plastic film is laminated on a non-woven fabric as shown in FIG. Was fed from a reel and fed while applying oil into a bending and forming device R formed into a C-shaped longitudinal section, commonly called a wrapper, gradually bent into two folds, and the tip portion was further bent slightly further inward and passed. Later, the string is sewn with a sewing machine M and cut to an appropriate length to manufacture a handbag for bags.

[0003]

In the conventional manufacturing method, as shown in FIG. 2, a band-shaped material Z obtained by laminating a plastic film on a non-woven fabric is forcibly inserted into a bending machine R having a C-shaped longitudinal section. It is necessary to bend while sliding the material Z in the retracting and folding forming machine R, and furthermore, the laminated plastic layer is highly viscous as is well known, and the frictional heat of high heat is generated by the vertical movement of the sewing needle to the sewing needle. Conventionally, before the material Z is fed into the folding machine R, the slipping of the material with said folding machine to produce
And oil was applied to prevent frictional heat of the sewing needle and the sewing machine hook was used to wipe off the oil adhering after sewing.However, the work of applying oil and then wiping the oil was not enough. If the oil is heated and the oil remains, the quality of the bags and the like is affected, so that careful work is required. Therefore, it is not only a troublesome manual work but also the work efficiency is low.

The present invention has conducted various researches and developments to solve the above problems. As a result, the oil application and wiping operations having the above-mentioned problems have been eliminated, and the operation efficiency has been automatically increased without requiring any manpower. It is an object of the present invention to provide a method for manufacturing a hand strap having a plastic film laminated thereon.

[0005]

In order to achieve the above object, the present invention provides a method for manufacturing a hand-held string laminated with a plastic film, for example, a part of an outer peripheral surface around which a water-permeable material is wound while rotating while being submerged. A water adhering device is provided on the outer peripheral surface of the immersion roll to allow the plastic layer side of the belt-shaped material Z to pass therethrough, and after the moisture is sufficiently adhered to the plastic layer side, the material Z is fed to the bending machine. is there.

[0006]

[Function] Since the plastic layer side is attached to the immersion roll which rotates while submerged, water sufficiently adheres to the plastic layer side, and even if the material Z is slid while being bent into a C-shape in the bending and forming machine, it slides smoothly. In addition, since the viscous friction of the plastic layer is reduced by moisture in the sewing machine needle, any adverse effect due to frictional heat can be completely eliminated.

Embodiments will be described with reference to the drawings.
In FIG. 1, a moisture adhesion device 1 is, for example, a cloth,
Alternatively, a submerged roll 2 surrounding a material having water permeability such as a sponge is rotatably supported in a water tank 3. More specifically, the lower half of the immersion roll 2 is immersed in the water 4 in the water tank 3, and the upper half is supported by the bearing 5 so as to rotate while protruding out of the water tank 3. The water tank 3 is provided at a position where the material Z to be fed into the bending and forming device R is unreeled from the reel 6 and proceeds in a belt-like state, and the material Z unreeled from the reel 5 is provided in the upper half of the immersion roll 2. Is fed to the bending and forming machine R after the water is adhered to it. Further, a tray 7 for receiving water drops may be provided at a lower position of the water tank 3. Furthermore, if a few drops of a neutral detergent containing a surfactant component are mixed into the water in the water tank 3, a further effect of reducing friction can be expected and processing of a thick product becomes possible.

[0008]

As described above, the method of the present invention for producing a hand-held string laminated with a plastic film can reduce the sliding friction of the material Z in the bending machine and the generation of frictional heat of the sewing needle due to the viscosity of the plastic. Therefore, unlike oil, it is easy to treat, has little effect on quality, dries naturally after sewing, eliminates the need for manual wiping, and can be expected to be automated with high work efficiency.
