ABSTRACT:
A picker spindle is provided having a barb angle of about 50 degrees or less with respect to the spindle axis. A shallow land angle, substantially reduced compared with prior art spindles, and a short gullet area between barbs prevent tight winding of the cotton between barbs. A gentle slope is defined for sliding the cotton easily in the axial direction off the end of the spindle. Less force is needed to unwind the cotton and remove it from the spindle and, as a result, the cotton doffs easier and doffer life is increased. The interval between doffer adjustments is also lengthened.
