Abstract
A picker bar includes spindles which are nonaligned in the vertical direction to define two or more offset sets of spindles on the bar and increase the number of spindles per unit length of the spindle bar. A spindle assembly includes a support carrying two spindles driven from a picker bar drive shaft by a single drive gear. Driven spindle gears are spaced on opposite sides of the shaft axis to facilitate close spacing of the spindles. A doffer column includes doffer pads of differing diameters to optimize doffing of the offset sets of spindles.
