Description

[Detailed Description of the Invention] Is the present invention one? This invention relates to a method for manufacturing a hooked elephant, in which multiple pairs of carpet hooks and female hooks are attached to the opening of a synthetic wood goods sheet armor booklet coated with heat bathed on behalf of RV.

Conventionally, the above-mentioned bags with hooks have been manufactured through the following steps.

■ One synthetic resin sheet is transported intermittently in the width direction■
Rinishi, that one? r#) The sheet is immersed in a heat bath at a position corresponding to the 941 edge of the rental body when the intermittent transfer is stopped, and the sheet is cut at the hot bathing part to create a rental body. A predetermined number of sheets are bundled and sent to the marking process (in most cases, this is a small-scale workshop like Ashiuchi Industrial, which is separate from the rental company's !+1! manufacturing factory).

■ In the marking process, the bundled binding body is
Peel off the pieces one by one, and mark the opening edge of each main body to indicate the positions where the male and female hooks should be fastened. Then, the binding bodies that have undergone this marking process are bundled again and sent to the two rods.

Q) In the hook-setting process, place one male (or female) small peck on one side of the opening edge of each main body, aligning it with the mark mentioned above, and then attaching two on the other side. Place seven female (or male) hooks at a time, aligning them with the above marks.

Conventionally, the hooks were attached after the binding body was manufactured, which increased the number of man-hours and was extremely inefficient.Moreover, the hooks were attached after the binding body was manufactured, and it was extremely inefficient. A very tedious manual process was required, such as enlarging the opening in honey-soaked blowing acid for each case.
It had drawbacks such as high cost.

In addition, the process of attaching the male and female hooks according to the marks itself is tedious and requires considerable skill.Moreover, the male hooks are attached at each location by 71mm, and the female hooks are attached at each location at 71mm. Because of the work of fixing each hook one by one, it is easy for the positions to shift, and even if the hook fixing position in any one part is shifted, when the male hook and female hook are mated, the position between the multiple pairs of hooks This causes the sheet to loosen or twist, making it look bad.
It will lose its value as a product.

In particular, when using a thin sheet, cut off diagonally both shoulders of the opening including the bath shield of the main body, and remove the seam of the opening.
Since it is necessary to fold the M portions inwardly and secure the hooks to the folded edges, the work is labor-intensive and costs are further increased.

The method of the present invention was developed in view of the above circumstances, and is capable of accurately fixing the *# pair of hooks in a predetermined position without causing any displacement of the fixing hitches, and
The aim is to efficiently and inexpensively obtain bags with hooks, and the synthetic resin sheet that is intermittently transported in the longitudinal direction is folded into one piece in the width direction, followed by a -C or two-folding process. , while the intermittent conveyance of the sheet is stopped and the folded sheet is cut in the heat bath and heat bath shield portions, a plurality of male hooks are attached to one of both edges of the sheet; It is characterized in that it is fastened at one o'clock, and a plurality of female hooks are fastened at the same time at positions corresponding to the fiber hooks at the other end.

Hereinafter, the w weave pattern of the method for manufacturing a hooked elephant according to the present invention will be explained based on illustrative drawings.

First, the bag manufacturing apparatus will be explained. 1 is a sheet feeding section that includes a pair of rollers 2.2 that rotate intermittently, and 3.4 is a pair of rollers 5, 5, 6, and 6 that rotate intermittently around a horizontal axis.
In a sheet drawer section equipped with Intermittent transport at corresponding pitches. Between the sheet 1 output part 1 and the sheet drawer part 3, there is a first sheet folding part 8 for folding and bonding both edges of the sheet a, which is intermittently transported, in one direction, and a first sheet folding part 8 for folding and bonding both edges of the sheet a, which is intermittently transported, to one side, and V −) V in cross-sectional view of g? In addition, the folded edge Fa" * A2 is folded back so that they do not touch each other, and the folded edge Fa"*1g of the inner edge of the folded edge by the second folding part 8 is defined as a fold line at a position offset from the center in the width direction. The second sheet folding section 9 is folded in two as
are provided in this order. These first and second sheet folding parts 8.9 are configured, for example, by folding the keratin on the axis of rotation in different ways for each small keratin, a plurality of pairs of rollers, a guide for defining the position of the folding line, etc. The loaf group of the first sheet folding section 8 is provided with a roller for applying adhesive.

In the second sheet folding section 9, there is also a lower side in the sheet transport direction.
While the conveyance of the single folded sheet is intermittently stopped, a plurality of male hooks A, A are attached at a predetermined interval to the upper folded edge 1 at the same time. Tick hitting that sticks 1111
G and a hook driver 11 that simultaneously fastens the same number of female hooks B, B at a predetermined interval on the lower folded edge 2 at a sheet transport pitch or an integral multiple thereof in the sheet transport direction. They are placed at intervals.

The hook making machines 10.11 may be installed in any order, and the female hook B,
B may be configured with a guard so that the male vines A, A are fixed to the upper folded edge -2.

Reference numeral 12 denotes a heat welding section, during which the sheets processed into single folded sheets are fixed in pairs and are intermittently bonded at the sheet folding section in the middle of nine hook groups X and X while the sheet conveyance is stopped. 11i is a cutting section which cuts the sheet e in synchronization with the heat bath bonding operation of the heat welding section 12.
is cut at the part that has been previously heated in a hot bath.

14 is a chute, and 15 is a collection section.

As shown in No. 4-, the male hook AFi is composed of the male fitting member south and the rivet member A2 integrally connected to the male fitting member south, and the female hook B is also #! The mold fitting member is composed of a rivet member B2 and is entirely made of synthetic resin acid.

According to the device described in item 1, the synthetic resin is intermittently transferred;
In the process of folding S/-F-, while the conveyance of the sheet 1 is intermittently stopped, a plurality of male hooks A, A are simultaneously fastened to one of both dense parts of the sheet g,
A plurality of female hooks B, B with the same number ζ are fastened to the positions corresponding to the other first-order male hooks A, Heat I between multiple pairs of ivy groups X and X.
At the same time as vyII is applied, the seam)g is cut at the preceding heat welding part, and a bag with a hook is manufactured.

Incidentally, the hook making machine 10.11 is installed above the second sheet folding part 9, and before folding the V-toe once, male hooks A,
#C may be configured to fasten A and female hook 1.1, but in the case of jin, between male hook and female hook,
For either one, a so-called reverse hook setting machine is required, which performs hook setting by reversing the vertical relationship between the male (or female 5) fitting member and the rivet member.

Also, 1 reporter 91! In the example, sheet a has a folded edge a
1. The object was to form a2 and fasten hooks A and B to that part.
It is also good to target something that makes B stick.

As described above, the method of the present invention includes a series of steps of completely folding an intermittent conveyed sheet into two, thermally welding the electric binding sheet F, and cutting the hot-bath bonded portion.
While the conveyance of the sheet is stopped, a plurality of male hooks and female hooks are attached to form a bag with hooks, so that the bag with hooks can be manufactured extremely efficiently. , since the IJI is to fasten several male hooks and female hooks at the same time, and since it is easy to establish a correlation between the simultaneous fastening layer of the hooks and the sheet that is intermittently transported, It is extremely simple and easy to align the relative positions of the hook and female hook as specified.This prevents the sheet from loosening or twisting at the bag opening, and improves the overall performance. It has become possible to provide inexpensive bags with hooks that look good and have a high value.
