ABSTRACT:
An apparatus for automatic rotational positioning of textile yarn winding tubes about their lengthwise axes while being transported on peg-tray tube carriers along a conveyor belt or other transport path includes a positioning station having a pair of rotatable positioning rollers disposed at the station along one side of the transport path at a sufficiently close spacing to one another to prevent passage of the peg trays therebetween. Each peg tray has a base plate whose annular surface is formed of a magnetically attractable material such as iron and at least the upstream one of the positioning rollers is magnetized to selectively exert a magnetic force on the peg trays at controllable intervals. As desired, the downstream positioning roller can also be magnetized.
