An article transporting, and preferably also color and/or weight sorting, assembly and method, support the articles (.g. apples or like pieces of fruit), and effect precise rotation (e.g. within about 5.degree.) of all apples transported thereby. This allows accurate determination of the apple's color by color sensing equipment (e.g. a color camera). The assembly comprises a support element, and two sets of cones mounted to the support by rotatable shafts, each set comprising first and second cones having a tapered exterior surface, the cones on each shaft facing each other and tapering to an imaginary substantially common midpoint. The cones support an apple essentially without the apple engaging the shaft. The cones may be of soft yieldable plastic or rubber with a first taper of about 25-35.degree. (e.g. about 28.degree.), and optionally one or more steps of different taper. The shafts are positively rotated substantially in unison by a gear mounted to the end of each shaft and engaging a stationary gear rack, so that for each 360.degree. revolution of a shaft an apple supported by the cones rotates substantially 120.degree.. The rack is designed to have only half or less the life of the gears.
