【発明の詳細な説明】
本発明は時計用らせんバンド原料の加工方法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for processing a raw material for a spiral watch band.
従来の方法によれば第１図に示すように芯金１が線材２
に対し相対的に矢印方向に回転し、ａｌの位置で巻きは
じめられたものが芯金１が１８０゜回転するとａ２、更
に３６０°（１回転）回転するとａ３というように順次
送り紙されていく。According to the conventional method, as shown in FIG.
When the core metal 1 rotates 180 degrees, it rotates in the direction of the arrow relative to the arrow, and the paper that starts winding at the position al is fed sequentially, such as a2 when the core metal 1 rotates 180 degrees, and a3 when it rotates another 360 degrees (one rotation). .
そのため巻き上げられた線材は回転軸と直角方向に対線
材中×−
し、θ−ｊａｎ ’−□−’のリード角が形成されバ
ンド巾
る。Therefore, the wound wire is twisted in the pair in the direction perpendicular to the rotation axis, and a lead angle of θ-jan'-□-' is formed and the band width is formed.
このリード角は第３図に示すように時計ケース４に上記
の原料を用いたらせんバンド３ａを取付けるとθの角度
分だけバンドの線材間の合わせ目に傾斜が現われること
になり、外観品質が損なわれる。As shown in Fig. 3, when the helical band 3a made of the above-mentioned raw material is attached to the watch case 4, the lead angle will be inclined by an angle of θ at the seam between the wires of the band, and the appearance quality will deteriorate. be damaged.
本発明は上述の問題を解決するためのものである。The present invention is intended to solve the above-mentioned problems.
図面に示す実施例により、本発明を詳述する。The invention will be explained in detail by means of embodiments shown in the drawings.
第２図は回転軸Ａ−Ｂに対し、芯金１の平面形状中心線
をリード角０分の角度をもたして取付、矢印方向へ芯金
を回転させ巻き上げたときの状態図であり、第２図Ｉの
ｂｌの位置で巻きはじめられた線材は芯金１が回転軸を
Ａ−Ｂとし１８−０°回転すると同図Ｈの状態となりｂ
２へ、更に１８０゜回転すると同図Ｉのｂ３へと順次移
動し、リード角は同図Ｉの場合は芯金中心線に対しては
直角に、同図Ｈの場合はθの２倍となって現われる。Fig. 2 is a state diagram when the core metal 1 is mounted with the planar center line of the metal core 1 at an angle of 0 minute lead angle with respect to the rotation axis A-B, and the core metal is rotated in the direction of the arrow and wound up. When the core metal 1 rotates 18-0° with the rotation axis A-B, the wire rod started to be wound at the position bl in Fig. 2 I will be in the state shown in Fig. 2 H, b
2, and then further rotated by 180°, it moves sequentially to b3 in I of the same figure, and the lead angle is perpendicular to the center line of the core metal in the case of I in the same figure, and twice as much as θ in the case of H in the same figure. It appears.
同図Ｉの面を表にしてこの原料を使用すれば表面のりド
角は解消され、このようにして作られたバンド３ｂを時
計ケース４に取付ければ第４図のように線材の合せ目に
リード角の現われない外観のよいバンドが得られる。If this raw material is used with the side I in Figure 4 facing up, the surface glide angle will be eliminated, and if the band 3b made in this way is attached to the watch case 4, the joint of the wire will appear as shown in Figure 4. A good-looking band with no lead angles can be obtained.
本発明によればらせんバンドの宿命とされていた線材の
合せ目のリード角を解消することができその効果は顕著
である。According to the present invention, it is possible to eliminate the lead angle at the seam of the wire, which is the fate of a helical band, and the effect is remarkable.
