Abstract: Methods and apparatus for spooling a flexible member onto a drum with a spooler assembly. In certain embodiments, a spooler assembly comprises a spooler arm operable to guide a flexible member onto a drum rotating about a drum axis. A first actuator moves the spooler arm in a first direction that is parallel to the drum axis. The first actuator operates in a first mode wherein the flexible member is allowed to free movement in the first direction and a second mode wherein the first actuator controls the movement of the flexible member in the first direction. The spooler assembly may also comprise a second actuator that moves the spooler arm in a second direction that is perpendicular to the drum axis.

Abstract: A thread guide (33) for traversing and guiding a thread (5) in a rotating winding bobbin (1) for producing a cross-wound bobbin in a bobbin winder of a textile machine by controlling vibrations of the thread guide. The thread guide (33) is permanently and directly connected to at least one energy accumulator (20,21) throughout the entire traversing motion. The potential energy of the energy accumulator (20,21) increases continuously after the dead center of the traversing area. A substantially harmonious oscillating mechanical system is thus formed with the thread guide.

Abstract: 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.
