Method for making seam of bag body

The invention relates to a method for manufacturing a seam of a bag body, in particular to a bag body made by sewing a stone paper with environmental protection characteristics as an innovative invention application.

According to the modern and highly developed industrial and commercial society, the demand for most people to carry a variety of personal belongings in a simpler and lighter way has been greatly improved. For example, in order to reduce the environmental protection purpose of plastic bags, when shopping in a shopping mall It should be provided with an environmentally-friendly shopping bag, and it is generally made like a bag of a shopping bag. Generally, a long strip and two side fabrics are cut out. When making, the three consecutive edges of the side cloth are corresponding and long. One side of the strip is sewn together, and the other side of the strip is stitched together with the other side of the long strip, and then the handle is sewn to complete the production of a carryable bag; however, The above is a soft cloth manufacturing process, which can complete the sewing technology in a large area at one time.

Further, it is necessary to protect the built-in items when the items are placed in the bag. The weather is changeable. In order to avoid the rainy season due to climate change, the bags have been replaced with rain-proof materials, so that the built-in items are not wetted, and the general waterproof materials are made of plastic, but due to the plastic material. It is not environmentally friendly and has pollution problems, so it has gradually eliminated the selection of plastic materials.

Due to the above problems, a more environmentally friendly paper has been developed, which is stone paper, which is a new material between paper and plastic, which can replace traditional partial functional paper, professional paper, and Replaces most traditional plastic packaging. It has the characteristics of low cost and controllable degradation, which can save the user a lot of cost and no pollution. From the perspective of replacing traditional paper, it can save a lot of forest resources for the society and reduce the secondary pollution generated in the papermaking process. From the perspective of replacing traditional plastic packaging, it can save the country a lot of strategic resources. The product can be degraded after use without causing secondary white pollution. The environmentally-friendly new material stone paper industry is widely used, and the product upgrading, technology upgrading, and expansion of the application field are very broad. It is a sunrise industry with strong vitality.

However, because stone paper has a suitable hardness and non-softness, it is not easy to be bent. Therefore, when using stone paper as the bag body sewing, it is not easy to implement the traditional cloth sewing method, which increases the difficulty in processing. It is also impossible to form the seams smoothly, and after the forced seaming, there will be unnecessary creases on the surface of the stone paper, resulting in a phenomenon that the product is not beautiful.

Today, the inventor has years of experience in the design, development and practical production of the relevant industries, and has researched and improved the existing structure to provide a sewing process for the bag body. Methods, in order to achieve better practical value for the purpose.

SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for manufacturing a seam of a bag body, which is intended to be produced by sewing a stone paper having environmentally friendly characteristics.

The main purpose and effect of the method for manufacturing the seam of the bag body of the present invention are achieved by the following specific technical means: the stone paper material is mainly used to form a bag body, which comprises a long base material and two side sapwoods, wherein The long substrate is divided into a bottom layer region and two side edge regions, and the two side sap materials are respectively fixed to the two end edges of the bottom layer region of the long substrate to be applied to the first stage sewing processing program, and then, The two side edges of the long base material are respectively fixed corresponding to the edges of the side sapwoods to perform the second stage sewing process; thereby, a three-dimensional shape of the bag body is completed, so that the whole body can be used. More practical convenience.

The method for manufacturing a seam of a bag body as described above, wherein the side sapwood is previously processed to have a edging strip at the top edge.

The method for manufacturing a seam of a bag body as described above, wherein the pre-processing comprises further comprising a edging strip on the outer edge of the two side edges of the long substrate.

The method for manufacturing a seam of a bag body as described above, wherein the side edge material is further processed to include a handle with a handle at the top edge.

It can be seen from the above components and implementation description that the present invention has the following advantages as compared with the prior art:

1. The sewing method for the bag body of the present invention can be processed by a two-stage process The stone paper material with hardness is evenly sewn into a bag body, and an environmentally friendly storage bag is completed.

2. The method for manufacturing the seam of the bag body of the invention can be processed by the two-stage processing sewing, so that the stone paper material with hardness can be easily processed, and the utility model has the advantages of convenient and rapid application.

For a more complete and clear disclosure of the technical content, the purpose of the invention and the effects thereof achieved by the present invention, the following is a detailed description, and please refer to the drawings and drawings: First, please refer to 1 to 6 is a block diagram showing the flow of the sewing process of the bag body of the present invention, which mainly uses stone paper to cut into a long substrate (1) and The two side sapwoods (2) are sewn into a bag body, and the steps are as follows: A) First stage sewing - dividing the long substrate (1) into an underlying region (11) and two side regions (12), The bottom edges of the two side sapwoods (2) respectively correspond to the two end edges of the bottom layer region (11) of the long substrate (1), and respectively cover the edging strips (3) and are fixed by sewing to form separately Standing support bar (S); B) second stage sewing - the two end edges of the two side edges (12) of the long substrate (1) respectively correspond to the two end edges of the two side sapwoods (2) Cover the edge strip (3), and then fix the seam to form a bag body (A).

Referring to the first to eighth figures, when the bag body of the present invention is manufactured, the two side sapwoods (2) are first subjected to a pre-processing step before the stage sewing, and the pre-processing step includes The edging strip (3) is wrapped around the top edge of the side sapwood (2) and the outer edge of the two side edges (12) of the long substrate (1) for sewing, and at the same time, the handle (4) is also corresponding The sewing seam is fixed at the top edge of the side sapwood (2) so that the top edges of the two side sapwoods (2) are completely covered and each has a carrying handle (4).

Next, the first stage sewing step is performed, and the long substrate (1) which is divided into the bottom layer region (11) and the two side edge regions (12) corresponds to the two side sapwoods (2), and the two side sapwoods (2) The edges of the bottom substrate (11) are respectively adhered to the edge edges of the bottom layer (11) of the long substrate (1), and are fixed by the wrapping edge strips (3) corresponding to the seams to sewn the two side materials (2). It is fixed to the bottom layer area (11) of the long substrate (1) so that the two sides of the sewn seam form a support strip (S) with strength and standing; after that, the second stage sewing step is carried out, Two ends of the positioned two side sapwoods (2) and the two sides of the long substrate (1) The two end edges of the zone (12) are fitted together, and then the edge strips (3) are respectively wrapped, and the seams are fixed to form a bag body (A), thus forming a three-dimensional bag body with a handle (A).

It can be seen from the above components and implementation description that the present invention has the following advantages as compared with the prior art:
