Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a mold for finishing molding of hosiery-based clothing such as stockings, pantyhose socks, and tights.

(Prior art) It is a well-known technology to mold and finish assembled, offset, and sewn stockings, panty socks, tights, and other sock-type clothing, such as in Utility Model Publication No. 43-5200. , Jikosho 51
-21199 etc. Furthermore, in Utility Application No. 60-89958, the applicant of the present application has proposed that when the thread material is a high-strength eccentric product using, for example, a highly elastic yarn or spandex yarn, the product once fitted into these molds. The finishing formwork has a large restoring force to return to its original shape, and tends to tend to shrink particularly in the length direction of the product, which causes wrinkles and sagging, reducing finished quality. , by providing a structure that effectively suppresses shrinkage in the length direction,
Eliminates the occurrence of wrinkles and sagging in high-power biased products.

Specifically, the finishing form is a set of two frame materials, in which unevenness for locking the finished material is formed at each base of both the frame materials, and the above-mentioned surface is formed between the two frame materials. It has been disclosed that a guide member for pushing the workpiece to be finished is provided corresponding to the locking unevenness.

(Problems to be solved by the invention) In the above-mentioned Utility Application No. 60-89958, in contrast to the conventional finishing formwork, as shown in Figure 4A, the front and rear edges of the base of a pair of frame materials are By providing unevenness and a guide member for pushing between the two frame materials, it is possible to tighten the waist or lumbar region of the material to be finished when making pant-taste tucks or finishing molding of tights using uneven fabric using strong power. By locking and restraining the irregularities and folding the workpiece inward by the guide member, the lower end portion (panty portion) of the workpiece to be fitted can be securely held, allowing free expression of significant contraction. This prevents the formation of wrinkles and sagging due to significant shrinkage in the length direction, and improves the quality of the finish by stably holding the material under moderate tension and suppressing shrinkage. was made so that it could be obtained.

However, knitted fabrics with greater elasticity are often used in panty pants, etc., and knitted fabrics with greater elasticity and stronger elasticity are used for the leg parts in particular, compared to the panty parts. Therefore, many finishing formworks have thin frame widths at the legs, and the balance between the formwork and the material to be finished at the panty section and the balance between the formwork and the material to be finished at the legs are important. As a result, it becomes difficult to reliably hold the fitted lower end portion (panty portion) of the workpiece only by folding it inwardly and supporting it with the guide member.

(Means for solving the problem) In order to solve the above problems, the present invention provides a structure for effectively suppressing shrinkage in the length direction of the finishing formwork. The guide member is designed to securely hold the lower end portion (panty portion) of the workpiece to be fitted, and specifically, a gripping portion with an uneven shape is provided on the side edge of the guide member that comes into contact with the workpiece. A guide member is provided to correspond to the uneven positions provided on both front and rear edges of the base of the pair of frame members of the finishing formwork, and the uneven shape is
By creating a sawtooth shape with a gentler angle on the insertion side of the workpiece and a steeper angle on the exit side of the workpiece, the guide member forms the same circumferential plane for the lower end portion (panty part) of the workpiece to be fitted. It is folded inwards to ensure secure clamping, makes it easy to insert the workpiece into the frame, and makes it difficult to pull out when the workpiece is removed from the frame. It is something.

The uneven holding portions may be appropriately set depending on the size of the material to be finished, rather than depending on the number of uneven portions.

(Function) According to the present invention, as shown in FIGS. 1 to 4, two frame members 1 and 2, which are flat in the illustrated example and have a shape corresponding to the outer shape and outline of the material to be finished, are used. 1
The lower ends of these frame materials 1 and 2 are fixed in parallel with pin shafts 3, etc., and the bases of each of these frame materials 1 and 2, i.e., the waist part of pantyhose, tights, etc. For those with a circumferential part), the frame material 1 of the part approximately corresponding to the waist part,
On both the front and rear edges in the width direction of the workpiece, projections and recesses 5 for locking the workpiece are formed by alternately and continuously forming convex portions 5a and recesses 5b. Although the formation position differs depending on the size and finishing width, at least the lowest protrusion 5a of the unevenness 5 is adapted to fit the lowermost edge (upper edge of the waist part) of the finished material to be fitted.

Between the two frame members 1 and 2, the locking unevenness 5
Correspondingly, as shown in FIG.
The upper and lower portions are formed vertically with b as the boundary, and the whole is approximately dogleg-shaped toward the center of the frame, and the inclined portion 6c has an uneven gripping portion 7 ( Fig. 4B) is provided, and the uneven shape has a sawtooth shape with a gentler angle on the insertion side of the workpiece and a steeper angle on the exit side of the workpiece, so that the workpiece can be When it is fitted into the frame, it is folded inward by the pushing guide member 6, and the lowermost edge (upper edge of the waist part) of the material to be finished is marked with reference numeral 1 in FIG.
0, it is supported so as to form the same circumferential plane and is held between the locking unevenness 5 and the gripping part 7 located at a position corresponding to the unevenness 5, and is securely grasped and placed at the base of the workpiece. There is no significant shrinkage in the length direction of the product due to the restoring force, no wrinkles or sagging, and no deterioration in finish quality, resulting in a beautiful finish, and when fitting the finished material into the frame material. is easy to insert, and difficult to remove when separating the finished material from the frame material.

(Example) Next, an example of the present invention will be described with reference to the drawings. In the illustrated embodiment, the frame members 1 and 2 are shown as being in the form of plates; however, unlike the formwork disclosed in Utility Model Publication No. 43-5200, which is the conventional example mentioned above, this is not a plate body but a wire. The same effect can be obtained with frames using other wires or bars, and the frame materials 1 and 2 can be made of plate materials such as aluminum or hard plastic, or wires or bars. In the embodiment, the formwork for panty tights 8 is shown, but it goes without saying that this formwork can have a contour suitable for each shape of the object such as tights.

This embodiment shows a structure in which the lower ends of the bases of the two frame members 1 and 2 are fixed by one or more pin shafts 3, but depending on the finishing method, for example, a bellows type It is also possible to use a connecting structure (see Japanese Utility Model Publication No. 51-21199) in which the two frame members 1 and 2 can be moved toward and away from each other.

In the embodiment, a rail groove 4 for movement is provided at the lower end of the base of frame materials 1 and 2 as a formwork installed in an automatic finishing machine.
As shown in Fig. 1, guidelines 9 are provided on the outside of each of the frame members 1 and 2 to regulate the insertion position of the finished material, but these are determined by the finishing method and type. It can be freely adopted depending on the object of the frame. In the unevenness 5 formed on both front and rear edges in the width direction of the frame members 1 and 2 at the base thereof,
The number and size of the convex portions 5a and the concave portions 5b are not particularly limited. However, as shown in Fig. 2 as an example, the uneven shape has a gentle angle on the insertion side and a gentle angle on the opposite side so that once the workpiece is inserted and engaged, it is difficult to come out. The angle on the side should be a little tighter than this.

In addition, the removable mounting structure of the guide member 6 for pushing is free to use a structure other than the one in the embodiment, and the upper sloped portion 6a of the guide member 6 is sloped in a direction that allows the workpiece to be easily received. be. Further, the bending angle a at the bending apex 6b, which is the center of the substantially doglegged shape, can be changed arbitrarily, but it is appropriate that the bending apex 6b be located in front of the unevenness 5. Next, the side edge of the guide member 6 that comes into contact with the workpiece, specifically, the lower inclined portion 6c of the guide member 6 is provided with an uneven gripping portion 7 consisting of a convex portion 7a and a concave portion 7b. The grip portion 7 corresponds to the position of the projections and depressions 5 provided on the bases of the frame members 1 and 2.

Instead of the gripping portion 7, as shown in FIG. 4C, a convex portion 7c may be provided on the sloped portion 6c of the lower half of the guide member 6, corresponding to the convex portion 5a of the unevenness 5, with the same effect. .

In the embodiment, the guide member 6 is installed on one side (rear side) of the frame members 1, 2, but it is also possible to provide two guide members 6, 6 facing each other on both sides. be.

(Effect of the invention) According to the invention, the conventional finishing formwork has an uneven shape 5 on the front and rear sides of the base of the pair of frame members 1 and 2, and the pushing guide member 6 has an uneven grip portion 7. The uneven shape has a sawtooth shape with a gentler angle on the insertion side of the workpiece and a steeper angle on the exit side of the workpiece. When performing taste toking and final forming of tights, the waist or lumbar region of the material to be finished is held and restrained by the unevenness 5, and is held inward by the uneven gripping portion 7 provided on the guide member 6. By fitting and gripping in a folded manner, the lower end portion of the fitted material to be finished is supported and securely held so as to form the same circumferential plane, and the free expression of significant contraction is prevented, making it suitable for use. It is possible to obtain a finishing molding effect, suppress the occurrence of wrinkles and sagging due to significant shrinkage in the length direction, and improve the finish quality by stably holding and suppressing shrinkage under moderate tension. It is an excellent product that can be used to finish forming pant-like pants, tights, etc. that are unevenly made using elastic threads or strong elastic threads such as spandex threads, and can also be used to finish forming finished materials without any problems. It is easy to insert when fitting into the frame material, and difficult to remove when removing the finished material from the frame material.
