フアスナは閉じる。 Here, the guide gear 9 meshes with the side surface of the pawl F 1 and forcibly adjusts its posture, so the opposing pawls F 1 hardly make any frictional contact with each other.
They mesh together smoothly. Therefore, the wear of the nails is extremely low. Further, the fastener is located between the running gear and the backup roller 8 and the guide roller 2.
Since it is held between 0 and 20, the fastener closes smoothly.

に大略平行となるので、布面からの歯車の突出高
さが低くなり、魚網のごとく、表裏共に充分な場
所（空間）を確保できる時に特に有利である。 With the second configuration, since the driving gears mesh from both sides of the fastener, the transmission force per gear is halved, the gear can be made smaller by that much, and smooth movement of the fastener can be obtained. In addition, since the circular end surface of the gear is approximately parallel to the fabric surface of the fastener part, the protrusion height of the gear from the fabric surface is reduced, which is especially advantageous when sufficient space can be secured on both the front and back, such as in a fishing net. It is.

不能などの不都合が激減する。 With the third configuration, the claws individually attached to the fabric portion can be aligned even if their directions are disturbed due to collision with a foreign object, etc., and the claws facing each other and close to each other can be smoothly engaged. Therefore, inconveniences such as wear and inability to mesh are drastically reduced.
第４構成により、バツクアツプローラが駆動歯
車から伝つた圧力角に相当する分力を受けて正確
な歯の噛み合いを促す。 With the fourth configuration, the back-up roller receives a component force corresponding to the pressure angle transmitted from the drive gear, thereby promoting accurate tooth meshing.
第５構成により、案内歯車を駆動歯車と同期し
て回転させると、よりスムーズな動きとなり、歯
車１個当たりの動力を半減でき、小さな歯車とす
