Abstract (en)

Postural change of a contact roller is accurately controlled even when a fluid pressure cylinder is employed. A yarn winder includes: a base 20; a bobbin holder 24 which is cantilevered by the base 20 and extends in a horizontal direction, bobbins B on which yarns Y are wound, respectively, being attached to the bobbin holder along an axial direction of the bobbin holder 24; a contact roller 25 which extends in the front-rear direction and applies a contact pressure to packages P formed by winding the yarns Y onto the respective bobbins B; a roller supporting member 30 which supports the contact roller 25 to be rotatable; an air cylinder 41 which is configure to posturally change a rear end portion of the roller supporting member 30 at least in the up-down direction; and an intervention mechanism 42 which intervenes between the rear end portion of the roller supporting member 30 and the air cylinder 41 and is configured to increase a load acting on the air cylinder 41 as the air cylinder 41 increases an upward postural change amount of the rear end portion of the roller supporting member 30.
