摘要
A yarn guide imparts a traversing motion to a yarn being delivered to a rotationally driven takeup bobbin in a textile yarn winding operation to create a cross-wound bobbin, or cheese. The yarn guide includes a fork-like yarn guide pivoted about a pivot axis substantially perpendicular to the axis of the takeup bobbin, and an electromagnetic mechanism for driving the guide. The electromagnetic mechanism includes an air gap, a plurality of magnets disposed along the air gap, a plurality of yokes and at least one electrical coil extending into and moveable along the air gap with the traversing yarn guide. The magnets are disposed along the air gap and generate magnetic field lines which extend in a substantially perpendicular direction through the air gap.
