Abstract
A machine for accomplishing the removal of leaves and other unwanted portions from vegetables comprising an elongate shear bar having two opposed, machined edges and a pair of elongate members mounted for rotation in close proximity to the machined edges. Each of the elongate rotary members are of the approximate length of the shear bar, and each has at least one helically configured raised portion extending along a substantial portion of its length, with the raised portion of each rotary member being arranged to operate close to the respective machined edge of the shear bar, such that a shearing action can be accomplished without damage to the vegetables. The direction of rotation of each of the elongate rotary members with respect to the adjacent machined edge of the shear bar, and the angle of the helically configured raised portions are such that vegetables or the like placed on the rotary members are caused to be moved toward one or the other of the machined edges of said shear bar, such that stems, roots or other unwanted components can be sheared from the vegetables as a consequence of the interaction between the raised portions of the rotary members, and the respective mach…
