ABSTRACT:
Disclosed is an open-end spinning machine which comprises a feed roller and a top roller for positively feeding a spun yarn from a spinning unit, a traverse guide for traversing the spun yarn in a direction perpendicular to the spun yarn feeding direction, a winding drum for frictionally rotating a conical surface bobbin for winding the traversed yarn to form a conical cheese, a guide or guides for absorbing yarn path length variations caused by the traverse motion of the spun yarn and by the conical angle of the conical cheese during the winding operation, a device for adjusting the guide in response to the conical angle of the conical cheese. By utilizing this machine, a good-shaped conical cheese of an open-end spun yarn having a uniform hardness along the axial direction of the cheese is obtained. Furthermore, this machine can be utilized for winding of various cheeses having various conical angles.
