摘要： A turret type precision winder having a turret disc on which a pair of bobbin chucks are held for carrying a working bobbin and an empty bobbin, respectively. A yarn winding operation is carried out on the working bobbin to form a package while a contact pressure is being applied on the package through a pressure roller. The pressure roller is controlled to be maintained at substantially a fixed position while the bobbin chuck of the working bobbin stepwisely moves away from the pressure roller. A positional relationship between the pressure roller, the bobbin chuck and a swingable member for supporting the pressure roller is defined so that a radial component f.sub.1 of the contact pressure reduces as a package diameter increases.

摘要： A turret type yarn winder comprising a first detecting means (32) for detecting the arrival of an empty bobbin at a yarn-transfer position (F) and outputting a signal, a second detecting means (46) for detecting the arrival of a traverse guide (5) at one turning point and outputting a sinal, a third detecting mean (47) for detecting the arrival of the traverse guide (5) at another turning point and outputting a signal and a pneumatic cylinder mechanism (42-45) for axially shifting a yarn traverse cam (4a) momentarily by a predetermined distance, whereby the traverse guide can be traversed while exceeding a yarn holding device (38) on the base end of a bobbin. The respective bobbin chucks (1a, 1b) are driven by a common motor via the respective clutch mechanisms (50, 167); the clutch mechanism (50, 167) being selectively maintained at one phase of either a full engagement, half engagement, or disengagement during he path of an orbital motion.
