Abstract

A winding apparatus is disclosed which includes a rotatable revolver having at least one spindle mounted thereon, with the spindle being adapted to coaxially mount one or more bobbin tubes. The revolver is rotatably mounted to the frame of the apparatus by a circular bearing surface of substantial diameter, which provides a very stable and durable mounting. The apparatus also includes a traversing mechanism for traversing an advancing yarn and so as to form a cross wound package on the tubes at the winding position. Also, a contact roll is mounted between the traversing mechanism and the winding position so as to be adapted to rest upon the surface of the package being formed. The contact roll is movable a limited distance radially away from the package being wound, and its position is sensed. To accommodate the build of the package, the revolver is positively rotated in response to the sensed position of the contact roll and so that the distance between the axes of the contact roll and the spindle is increased and the pressure between the contact roll and the package may be maintained within a small range of variation.
