A yarn winder, used for winding various kinds of yarns by automatically setting the moving speed of a bobbin holder so that it is suitable for the increasing size of the yarn package wound onto the winding bobbin holder. In the winder, while a contact roller (7) is pressed onto a bobbin (9) inserted onto a bobbin holder (8) or a yarn layer wound on the bobbin (9), a yarn (Y) is traversed by a traverse apparatus (6), and thus, the yarn is wound on the bobbin. The movement of the contact roller due to increase of the wound yarn is detected by a sensor (16), and the slider is moved based on signals detected by the sensor so as to move the bobbin holder in such a direction that it moves away from the contact roller. The slider is actuated by signals from the sensor detecting the amount of the movement of the contact roller, and the speed of the winder can be varied stepwise or continuously.

Yarn winder

A bobbin holder comprises a rotatable support member, a plurality of bobbin holding devices inserted onto the rotatable support member, and at least one cylindrical member inserted onto the rotatable support member and engaging with the bobbin holding device, so that bobbin holding devices are expanded so as to hold bobbins. A main compression member for radically expanding the bobbin holding devices is disposed at one end of the bobbin holder. At least one supplementary compression member for supplementing expansion force of the main compression member is disposed at an intermediate portion between a bobbin holding device located at the end where the main compression member is disposed and another bobbin holding device located at an opposite end.

Bobbin holder

A lubricating device of a turret type change-over device wherein a plurality of rotating bodies are mounted on a rotatable turret table, comprising: a plurality of bearings adapted to rotate the rotating bodies with respect to the rotatable turret table; a lubricating oil chamber provided in the vicinity of the bearings; and a lubricating oil tank provided within the lubricating oil chamber, the oil tank being rotated in accordance with the rotation of the turret table to retain a lubricating oil therein and supply the same to the bearings.
