Yarn guide for the traversing delivery of a yarn to a rotationally driven takeup bobbin

A yarn guide for delivering a yarn to a rotationally driven takeup bobbin in a bobbin winder of a textile machine, the yarn guide comprising:

• (a) a fork-like yarn guide pivoted about a pivot axis oriented substantially perpendicularly to the axis of the takeup bobbin, and
• (b) an electromagnetic mechanism for driving reciprocal pivoting movement of the yarn guide to impart a traversing motion to a yarn for creating a cross-wound form to the bobbin, the electromagnetic drive mechanism comprising:
• (i) an air gap having at least a first side and a second side and being penetrated by magnetic field lines,
• (ii) a plurality of magnets disposed along the air gap for generating magnetic field lines extending substantially perpendicularly through the air gap,
• (iii) a plurality of yokes disposed on at least the first and second sides of the air gap for conducting the magnetic flux, and
• (iv) at least one electrical coil extending into the air gap and being connected with the yarn guide for reciprocal movement within the air gap with the traversing motion of the yarn guide, wherein current may be controllably supplied to the at least one electrical coil.
