の張力を検出し、これに基づき巻取機の巻取条件の設定
変更をなす場合の張力検出、測定がある。As an example of a case where it is necessary to detect and measure the tension of a traveling yarn, when winding a fiber yarn, the tension of the yarn traveling to a winding machine is detected, and based on this, the winding conditions of the winding machine are determined. There is tension detection and measurement when changing settings.

この場合、巻取機において綾振りされる糸条を、張力検
出端に、間欠的に接圧せしめ、この接圧力を検出する技
術が、従来用いられて来た。In this case, a technique has conventionally been used in which the thread being traversed in a winder is brought into contact with a tension detection end intermittently and the contact pressure is detected.

これを図を用いて説明する。This will be explained using figures.

。In FIGS. 1a and 1), the thread 1 passes through the traverse fulcrum guide 2, is traversed by the traverse guide 8 of the traverse device 12, and is wound around the bobbin 10 to form the package 9.

が、巻取機１４のスピンドル軸１３の駆動部（図示省略
）の回転数を制御することによって行なわれる。The winding tension control at this time is such that the traversing yarn 1 intermittently contacts the detection guide 3 of the tension detector 6 near the traversing end as it traverses, causing distortion of the spring-like body 4. The gauge 5 is strained, and the tension controller 7 is operated in accordance with the amount of strain, and its output is controlled by controlling the rotational speed of a drive section (not shown) of the spindle shaft 13 of the winder 14.

このようにして巻取張力は所定値に制御される。In this way, the winding tension is controlled to a predetermined value.
