Abstract

PURPOSE:To obtain shoulder pads without contact due to stepped parts by sandwiching sheetlike materials of a different size having the peripheral part cut into a wavy form between two sheetlike materials of an optional shape consisting of various fibers and needle punching the sandwich and cutting the resultant pads into the shape of a pair of left and right shoulder pads. CONSTITUTION:Sheetlike material plates (1b), (1c) and (1d) of respective different sizes, not always limited by fibers and shapes of the lowermost and topmost sheetlike materials (1a) and (1e), but preferably having the peripheries cut into a wavy form are sandwiched between the lowermost and topmost sheetlike materials (1a) and (1e) using fibers prepared by mixing one or more of synthetic fibers with cotton, wool, hemp, etc., and at least one of plate units of a circular, square, triangular or a shape nearly resembling thereto and the resultant sandwich is needle punched with needles 2 having many prickles, integrated and cut into a pair of left and right shoulder pads to afford the objective shoulder pads.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to the manufacture of shoulder pads used for adjusting clothing.

(Prior art) ■ Conventionally, shoulder pads were manufactured using needle punching, but the material used for shoulder pads was wool,
Materials such as hemp, cotton, synthetic fibers, etc. are cut into disk shapes or similar shapes, quadrilateral shapes or similar shapes, triangular shapes or similar shapes, etc., and into different sizes such as large, medium, and small. The most suitable method for mass production has been to stack the materials in the order of large, medium, and small in the middle of a large material and needle them from above to form a single piece, and then cut this into a pair of left and right shoulder pads. .

(Problem to be solved by the invention) However, according to the conventional needle punch method,
There is a tendency for a step to appear on the outer periphery of each material made of different materials, and even if the step collapses slightly due to needling, the difference in step is often still clearly visible. For shoulder pads, it is desirable that this step be collapsed to create an inclined surface between the thick and thin areas.

(Means for Solving the Problem) In order to solve the above problem, in this invention, the edges of the intermediate large, medium, and small materials, excluding the top and bottom materials, are made corrugated so that the leading edge of the material is corrugated. The gradually tapered, almost triangular part is the lengthened part of the outer periphery where there is no internal pressure, and by needling, the part that tends to collapse outward is lengthened, thereby avoiding the occurrence of a stepped part that forms a negative line. This is what I am trying to do.

(Function) A disk-shaped or quadrilateral shape with rounded corners is placed between the top and bottom materials in the order of large, medium, and small.
When you put the largest top material on top of - and ring it from above to knee 1, you will be stabbed from above with many barbed needles, so the center part will be hardened due to strong pressure from the force being pushed from above. The peripheral part of the intermediate material can release the force applied from above to the outside, so the fibers forming the intermediate material lose their shape outward and are able to release the pressure from above. Become. In the case of this invention, the periphery of a circular, quadrilateral, or triangular shape is made into a corrugated shape, so the length of the periphery is doubled, so the periphery of the material pressed by the many barbed needles is The fibers around the material that have become long and compressed will escape the pressure and the portions that tend to collapse outward will become longer, and most of them will collapse without forming a step, creating an inclined surface. Therefore, after needling, the integrated mass of material does not have any steps around the large, medium, and small materials, and forms a sloped surface on the periphery, and after breaking into left and right pairs, there is a convex high part on the shoulder Ayk. A suitable inclined surface will be created around it.

(Example) A large IC 1b, a middle IC 1 and a small IC 1d are placed between the top two-face plate 1e and the bottom board 1a made of approximately circular synthetic fiber.
In this order, the synthetic fiber material is generally circular in shape, but the periphery is carved into a wave shape. When this is needle-punched with a needle punching machine, it is pressed by the needle 2 with many barbs, so the topmost part, The central parts of the lowest parts 1e, 1a and the intermediate materials 1b, 1c, ]d harden due to the pressing force, but the peripheries of the intermediate materials 1b, 1c, 1d can escape outward from the pressing force, and are wave-shaped. Since the edge line that can escape outward is twice as long, it collapses outward against the pressing force and escapes, forming a broken section, as shown by the arrow in Figure 3. Instead, an inclined surface is formed on the outer periphery.

This needle punching creates an ideally shaped, integrated shoulder center material with a high central portion and a sloped and low peripheral portion. This is then cut into a pair of left and right shoulder pads to create a shoulder pad with a semicircular shape with a high center at the cutting line and gradually lower edges.

In the present invention, the materials 1a, 1b, 1c, 1d, and 1e may be cotton, linen, wool, synthetic fibers, or a mixture thereof, and their shape may be not only disc-shaped but also quadrilateral or triangular.

(Effect) As described above, according to the present invention, when manufacturing shoulder bars, the large, medium, and small material plates between the bottom material board and the top material board are overlapped and stacked. During needling, the outer periphery of the intermediate material collapses and forms a slope due to needle punching, eliminating the occurrence of bumps and steps at each peripheral edge of the intermediate material as in conventional manufacturing methods. .

Figure 1 is a perspective view of the constituent materials when carrying out this invention, and Figure 2 is a diagram of the stacked constituent materials being needle-punched from the top with a needle pointing downward (the topmost material has been removed for clarity). ) FIG. 3 is a perspective view showing where the wavy (triangular) portion at the periphery of the intermediate material tends to collapse outwards due to needle punching. In the figure, 1 is a material plate, and 2 is a needle with several barbs.

Claims (1)

[Claims] The bottom and top panels are made of one or more of synthetic fibers, cotton, wool, linen, or a mixture of two or more of these, and are made of a type of plate in a circular, quadrilateral, triangular, or approximately similar shape. Needle punching is performed by sandwiching plate-like materials of different sizes with wave-shaped peripheral edges, although the fibers and shape of the lowermost plate-like material are not necessarily restricted between the upper plate-like materials. A method for manufacturing shoulder pads, in which the pieces are made into one piece and then cut into a pair of left and right shoulder pads.
