Abstract

PURPOSE:To elevate the productivity of buttons with skin leather so as to fuse a skin on one side thereof by providing a sheet-shaped circular flange section on the circumference of a core material while being cut at the fused part integrally. CONSTITUTION:A button comprises a core material 10 made of a thermoplastic resin and a skin 20 made of a thermoplastic resin covering the outer side of a hemispherical head 11 of the core material 10 and a mounting leg 12 is formed integral roughly at the center of the undersurface of the head 11 of the core material 10. The leg 12 of the core material 12 is fitted securely into a mounting substrate 31 buried into a sheet back and a skin material 20' is placed on the circumferential surface of the head 11. Thereafter, an ultrasonic welder phone 32 is put over it from above to impart an ultrasonic wave so that the skin material 20' is fused on the upper side of a circular flange section 13 of the core material 10' while the skin material 20' and the circular flange section 13 are cut integrally at the fused section along the circumferential shape of the button.

の中で芯材が回転するという問題がある。Such buttons with skins are used as decorative buttons and practical buttons on clothing, sheets, etc. In conventional buttons with skins, a plurality of crimping claws provided on the outer periphery of the core material are attached to the core material. The outer surface of the core material is caulked onto the outer skin covering the outer surface of the core material, and the outer skin is held between the claws, or the core material is sandwiched between two upper and lower skin materials, and both of these skin materials are fused around the outer periphery of the core material. By wearing it, the outer skin is integrated with the core material. For this reason, both of these methods cannot be said to have high productivity, and the latter method in particular has a problem in that the core material rotates within the bag-shaped skin.

The main purpose is to improve the productivity of this type of button with a skin and to prevent the core material from rotating relative to the skin.

付ボタンの製造方法をその要旨とするものである。In order to achieve this object, the present invention provides a method for manufacturing a button with a skin, in which the outer surface of a core material having a predetermined shape is covered with a skin made of thermoplastic resin, and the skin is integrated with the core material. , a thin plate-like annular flange is installed around the outer periphery of the core material, a skin covering the core material is fused onto the -side surface of the annular flange, and the annular flange is attached at the same time as or after the fusion. The gist of the present invention is a method for manufacturing a button with a skin, characterized in that the button and the skin are cut integrally at the fused portion or the outer periphery thereof.

飾模様を付与したものが好ましい。In the present invention, a circular, oval, polygonal, or other synthetic resin core material is suitable as the core material, and in particular, a core material made of the same material as the epidermis is preferable in consideration of fusion with the epidermis. In addition, woven fabrics, knitted fabrics, sheets, films, etc. made of thermoplastic resins such as polyolefin, polyester, polyamide, and polyvinyl chloride are used as the skin, and in particular, the surface is subjected to calendering, embossing, etc. It is preferable to use a decorative pattern provided by printing or the like.

できる。Therefore, in the present invention, when the core material is molded, the skin is fused onto one side of the thin plate-like annular flange part integrally provided on the outer periphery of the core material, and the skin and the annular flange part are integrally cut. Therefore, the productivity of buttons with skins can be improved compared to the above-described caulking means or means in which the core material is sandwiched between two upper and lower skin materials and the two skin materials are fused together. .

が防止される。In particular, in the present invention, if fusing and cutting are performed at the same time (weld cut), the productivity can be further improved. Further, according to the present invention, since the core material and the skin are reliably integrated, rotation of the core material with respect to the skin is prevented.

。The core material 10' includes a thin plate-shaped annular flange portion 13 on the lower end periphery of the head 11 of the core material 1o.
A leg portion 12 is provided approximately at the center of the lower surface. , the core material 10' is molded by injection molding or the like, but the head 11
The one leg portion 12 and the annular flange portion 13 are integrally formed. In this embodiment, an ultrasonic weld cut method is used, and the core material 10' is placed on a jig 31 as shown in FIG. Place the material 20'. After that, an ultrasonic welder horn 32 is placed over the head 11 of the core material 10' and the skin material 20', and the skin material 20' is attached to the annular flange portion 1 of the core material 10' using the tip blade portion 32a of the ultrasonic welder horn 32.
3 and apply ultrasonic waves. The tip blade part 32a of the welder horn 32 has a shape that follows the outer peripheral shape of the button, and simultaneously fuses the skin material 20' to the upper surface of the annular flange part 13 of the core material 10', and at the same time The skin material 20' and the annular flange portion 13 are integrally cut along the outer circumferential shape of the button. That is, the skin material 20' and the annular flange portion 13 are weld-cut using the welder horn 32. As a result, a button (not shown in FIG. 1) consisting of a core material 1o and a skin 20 is manufactured.

Since the paulownia skin material 20' and the paulownia skin material 20' are simply weld-cut at the annular flange portion 13 of the core material 10', the conventional caulking method and the core material are sandwiched between two upper and lower skin materials to separate both skins. The productivity of buttons can be significantly improved compared to methods of fusing materials together. Further, according to the manufacturing method of this embodiment, the core material 10 and the skin 2o are reliably integrated, so that the core material can be bonded to the skin 2o as in the case of a button by means of fusing both skin materials together. There is no rotation relative to the

Further, in the present invention, as shown in FIG. 5, the core material 10' can be used as the annular flange portion 13', which is produced when molding is performed using a mold with low machining accuracy. In this case, there is an advantage that the mold cost for the core material 10' is low and the manufacturing cost of the button can be reduced. Furthermore, in the present invention, in the manufacturing method of the above embodiment, not only the outer surface of the head 11 of the core material 10' but also the lower surface of the head 11 is covered with the skin material 20'.
It can be coated with Even in this case,
A weld cut can be used, and the front and back skins can be securely fixed to the core material, and the core material will not rotate within these two degrees.
