Description

前記エプロン駆動ローラへ前記通気エプロンを押圧する押圧ローラをさらに備え、前記押圧ローラと前記最終送出ローラ対とで一部のローラが共通に設けられている。この構成によれば、通気エプロンと最終送出ローラ対との間を繊維束が移動する際に、繊維束は常に共通ローラと接触する状態で移動する。そのため、集束した繊維束の繊維配列が乱れることが抑制される。また、繊維束集束装置を構成する部品点数が少なくなる。また、前記エプロン駆動ローラと前記最終送出ローラ対とで一部のローラが共通に設けられている。 Further comprising an apron pressing roller for pressing the apron to the drive roller, a part of the roller in the previous SL pressing row La and the final delivery roller pair are commonly provided. According to this configuration, when the fiber bundle moves between the ventilation apron and the final delivery roller pair, the fiber bundle always moves in contact with the common roller. Therefore, disorder of the fiber arrangement of the bundled fiber bundle is suppressed. In addition, the number of parts constituting the fiber bundle focusing device is reduced. In addition, some rollers are provided in common for the apron driving roller and the final delivery roller pair.

前記エプロン駆動ローラと前記最終送出ローラ対とで一部のローラが共通に設けられている場合に、前記吸引パイプがトップ側に設けられていることが好ましい。吸引パイプが、トップ側に設けられていると、共通のローラはボトム側に設けられるため、繊維束集束装置を構成するボトム側のローラの数が少なくなり、風綿が溜まり難くなる。
If some of the rollers are commonly provided between the apron driving low la and the final delivery roller pair, it is preferable that the suction pipe is provided on the top side. When the suction pipe is provided on the top side, since the common roller is provided on the bottom side, the number of rollers on the bottom side constituting the fiber bundle concentrating device is reduced, so that the fluff is less likely to accumulate.

Claims
