Abstract: A multi-end revolving type automatic winding machine exhibiting high operationality, threading operability and space efficiency, and arranged such that two turret tables (3, 3?) are disposed on the opposite sides of a yarn passage, rotational directions of a press roller (9) provided for one turret table (3) and a press roller (9?) provided for the other turret table (3?) are reversed, rotational directions of one turret table (3) and the other turret table (3?) are reversed, and the center of each press roller (9, 9?) touching a bobbin holder or a yarn being wound during winding of yarn is located between an imaginary line c connecting the centers of two bobbin holders (4, 5) projecting from one turret table (3?) and an imaginary line c? connecting the centers of two bobbin holders (4?, 5?) projecting from the other turret table (3?).

Abstract: A yarn winder is provided for winding the yarn on a plurality of bobbin holders (4), (5), (4?), and (5?) at the same time, a plurality of traversing support point guides (12) and (12?) is arranged in parallel to a direction that is orthogonal to an axial direction of a bobbin holder at an upstream position of traverse devices (30) and (30?), the plurality of traversing support point guides is arranged in parallel to the direction that is orthogonal to the axial direction of the bobbin holder during hanging up of the yarn so as to wind the thread on the plural bobbin holders at the same time, and the plurality of traversing support point guides can be aligned in the axial direction of the bobbin holder when hanging up the yarn on the traversing support point guides.

Abstract: A bobbin holder mounted on a yarn winding machine includes a plurality of chucking members disposed at an outer periphery of the holder. The chucking members are expanded radially outwardly so as to engage an inner side of a cylindrical bobbin coaxially inserted onto the holder when they are longitudinally compressed. The chucking members release the bobbin when they are moved radially inwardly. The portions on the holder for receiving the chucking members are formed as concaves, with a part of each chucking member inserted into a respective concave.
