Description

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

(Prior art) It is a well-known technology to mold and finish assembled, knitted, and sewn hosiery clothing such as panty pants and tights.
Examples include Utility Model Publication No. 43-5200 and Utility Model Number 51-21199. The former, as disclosed in the same publication, involves fixing two elongated wire foot frames, which form the contours of the waist and foot parts of tights, in parallel on a rectangular base frame also made of wire. A push-in frame formed by bending a piece of wire into a curved rectangle is interposed between the front upper parts of the two leg frames, and the tights are fitted from the lower end of the leg frame and pulled up. is flattened along the two leg frames, and the common waist part is fitted outwardly in a slightly bulging shape over the top of each of the two leg frames, and the crotch part of the waist part is pushed inwards along the frame. The folded shape is molded and finished (see the same publication for details), and the latter is used as a pant-taste-tucking foot last to stand parallel to the die border machine (see the same publication for details). Attach one end of the guide member to the inner side of each base of the pair of foot lasts provided, bend the free end (other end) of each guide member diagonally upward and outward,
A pair of foot lasts to which guide members are attached are placed opposite each other so that the guide members are arranged diagonally, and a pantaste fitting is placed over the foot lasts from the waist part, and the waist part is connected to the waist part through the guide member. It is designed to be folded inwards (see the same publication for details). Of course, the above two examples are only one of the many types of foot molds that exist, but as can be seen in both cases, a set of two molded foot molds made of wire or plate material are erected in parallel. Then, the legs of the product to be finished are individually placed on these lasts, and the hips are commonly placed on top of each other, and tension is applied to the legs to give a finishing finish with or without the necessary thermal means.

(Problem to be solved by the invention) In this type of finishing form, if the knitting material of the socks-type clothing is a normal thread material, there will be no problem with the conventional type, but the thread material For example, in the case of knitted products with strong power using highly elastic processed yarn or spandex yarn, the restoring force of the product that tries to return to its original state once fitted into these forms is large, and the product's It tends to tend to shrink significantly in the length direction, resulting in wrinkles and sagging, which poses a problem in that it reduces the quality of the finished product.
In panty pants and tights products that are knitted and produced using special thread materials such as those mentioned above, they are assembled in advance into small sizes, and in the final forming process, they are tightened and set to the normal foot size. Therefore, the above phenomenon occurs frequently.

(Means for Solving the Problems) 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. ,
This product is designed to eliminate wrinkles and sagging in high-power knitted products.
An uneven part 5 for locking the waist part 10a of the material to be finished 10 is formed on each base of both the frame materials 1 and 2 of the finishing formwork, which is a set of two frame materials 1 and 2. The locking uneven portion 5 is provided between the frame members 1 and 2.
Corresponding to this, a guide member 6 for pushing the workpiece 10 is inserted.
This is a finishing formwork for socks, in which the tip of the locking convex portion 5a is located approximately on an extension of the outer edge of the frame members 1 and 2, and the guide member 6 is located at the waist of the material to be finished. In order to pull the portion 10a in the length direction, an inclined portion 6c is formed whose distance from the edge of the frame material decreases toward the tip of the waist portion 10a.

(Function) According to the technical means of the present invention, the waist portion 10a (hereinafter also referred to as the waist portion or the waist portion) of the workpiece 10 fitted into the frame members 1 and 2 is The guide member 6 pressed against the portion is locked to the locking protrusion 5a, and shrinkage in the length direction is prevented.

Since the locking convex 5a does not protrude outward beyond the extension of the outer edges of the frame materials 1 and 2, it does not leave convex marks on the waist portion 10a of the workpiece 10, and the guide member 6
is inclined so as to approach the outer edge of the frame material as it approaches the tip of the waist portion 10a, thereby preventing the waist portion 10a from shrinking in the length direction.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 4, in the illustrated example, two frames 1 and 2, which are flat and have a shape corresponding to the outer shape and contour of the material to be finished, are used as a set. , 2 are fixed in parallel with each other by pin shafts 3 in the illustrated example, and the bases of each of the frame materials 1 and 2, that is, the waist portions of panty pants, tights, etc. In some cases, unevenness 5 is formed by alternately and continuously forming convex portions 5a and concave portions 5b on both the front and rear edges in the width direction of the frame members 1 and 2 in a portion substantially corresponding to the waist portion, respectively.
At this time, the formation position of the unevenness 5 differs depending on the size and finishing width of the target material to be finished.
At least the lowest protrusion 5a in the unevenness 5
is adapted to fit the lowermost edge (upper edge of the waist part) of the finished material to be fitted. The locking convex portion 5
The tip of a is located on an extension of the front and rear outer edges of the frame members 1 and 2, and does not protrude from the outer edges.

Further, between the two frame materials 1 and 2, a guide member 6 for pushing the material to be finished is formed with inclined portions 6a and 6c above and below with the bent top portion 6b as a boundary, as shown in FIGS. The entire guide member 6 is approximately dogleg-shaped toward the center, and the guide member 6 is shown in the figure as follows.
The notch 7 formed at the lower end is made to straddle the fixing pin shaft 3 of the frame members 1 and 2, and the holding shaft is removable via the threaded portion 8a, mounting hole 9, etc. between the frame members 1 and 2. 8 to hold it in a fixed state and interpose it. That is, the guide member 6 has an inclined part 6c that presses the crotch part of the workpiece fitted into the frame members 1 and 2 and prevents the waist part from being pulled upward by the contractile force. The sloped portion 6c is sloped so that the distance from the outer edge of the frame material decreases as it goes below the frame members 1 and 2, that is, toward the tip of the waist portion, while the sloped portion 6a decreases as it goes toward the tip of the foot. It approaches the outer edge of the frame material and protrudes outward, and guides the waist portion so as to correspond to the inclined portion 6c when fitting the material to be finished onto the frame materials 1 and 2.

As a result, as shown in FIGS. 3 and 4, for example, the panty pants 10 can be
The stockings 10 are fitted into the pair of frame members 1 and 2 from 0a and pulled down downwards, so that both leg portions 10b and 10b of the stocking 10 are fitted into the frame members 1 and 2.
The waist part 10a is divided into two parts and fitted together.
3 and 4, is guided inward by the guide member 6 in a convoluted manner, and the waist portion is fitted around the two members 1 and 2 by the frame member It is locked by each unevenness 5 formed on both the front and rear edges of the bases 1 and 2, and together with the guide member 6, it is stably held under appropriate tension. Therefore, even when subjected to the finishing molding process, shrinkage in the length direction is appropriately suppressed by the waist portion 10a being locked and restrained by the unevenness 5, and the high elasticity processed yarn is This makes it possible to prevent the occurrence of wrinkles and sagging that occur after forming and processing of high-power knitted fabrics using spandex yarn, etc., and to prevent deterioration in finished quality.

In the illustrated embodiment, the frame members 1 and 2 are shown as being in the form of plates; The same effect can be achieved with a frame made of wire or other wires or bars.
Further, as the material of the frame materials 1 and 2, for example, a plate material such as aluminum or hard plastic material, wire, or bar material can be used. In the embodiment, a formwork for pantaste packing 10 is shown. It goes without saying that the shape and outline of the product are appropriate for the shape of the tights and other target products. In addition, 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 movable 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 formwork installed in an automatic finishing machine is shown in which a rail groove 4 for movement is formed at the lower end of the base of frame members 1 and 2, and as shown in FIG. Guideline 11 for regulating the insertion position of the finished material on each outside of the
are provided, but these can be freely adopted depending on the finishing method and the object of the formwork. In the unevenness 5 formed on the front and rear edges of the frame members 1 and 2 in the width direction at the base thereof, the number and size of the protrusions 5a and the recesses 5b are not particularly limited, but as shown in the example in FIG. In addition, the uneven shape has a gentle angle on the entry side so that it is difficult for the material to come out once it is inserted and engaged, and on the other hand, the angle on the exit side is slightly smaller than this. It is appropriate to make the angle tight. Furthermore, the removable mounting structure of the pushing guide member 6 may be any structure other than the one in the embodiment, and the upper inclined portion 6a of the guide member 6 is inclined in a direction that facilitates the reception of the workpiece. be. In addition, the bending angle α at the bending apex 6b, which is the center of the dogleg shape, can be changed arbitrarily, but the position of the bending apex 6b may be set to correspond to or in front of the uneven portion 5. Appropriate. 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.

(Effects of the invention) According to the invention, by providing the unevenness 5 and the guide member 6 for pushing on the front and rear side edges of the base of the pair of frame members 1 and 2 in the conventional finishing formwork, When knitting panties with strong power or finishing forming tights, the waist or lumbar region of the material to be finished is locked and restrained by the unevenness 5 and folded inward by the guide member 6. By fitting and supporting the workpiece, it is possible to securely hold the lower end of the fitted material and prevent the free expression of significant shrinkage, thereby achieving a suitable finish forming effect and preventing significant shrinkage in the length direction. It suppresses the occurrence of wrinkles and sagging, and improves the quality of the finish by stably holding it under moderate tension and suppressing shrinkage. This is an excellent product that can be used to finish knitted pantyhose, tights, etc. without any problems. In addition, the locking convex portion 5a locks the workpiece by the contractile force of the workpiece and the pressure of the guide member 6, but its tip is located approximately on the extension of the outer edge of the frame members 1 and 2. Therefore, it is possible to further improve the finishing quality without leaving too many convex marks on the material to be finished, and the distance between the guide member 6 and the edge of the frame material decreases as it approaches the tip of the waist portion. Slanted portion 6c
Therefore, the inclined portion 6c itself also has a function of preventing shrinkage of the material to be finished in the length direction, and shrinkage control can be more reliably performed.
