Abstract

The method of orienting plastic pipe fittings in predetermined positions by passing the fittings downwardly through an inclined, rotating tube having a relatively smooth-walled bore so that the frictional agitation of the gravitating articles permits them to settle into a predetermined position with the center of mass in the lowermost possible position. The rate of rotation and the angle of incline are adjusted for different articles, and tubes of three different sizes are provided for interchangeable use. Two pairs of supporting rollers on opposite sides of the tube position are engageable with axially spaced annular collars on the tubes, the collars being sized to hold the tubes at the same discharge level and one of the rollers of each pair being driven by a variable speed motor to rotate the tube.
