ABSTRACT:
Corn detasseling apparatus is disclosed that comprises first and second sets of cylindrical segments aligned end-to-end to form first and second rollers, respectively, that are mounted on a frame in parallel contacting relationship. The circumferential surfaces of the cylindrical segments of the first roller are in contact with those of the second roller to define a detasseling nip. Since it is preferred that the circumferential surfaces of the cylindrical segments be made of a resilient material, the segments can be inflatable tires that are abutted end-to-end to form a roller, and in which case the circumferential surfaces are on the treads of the tires. In accordance with the present invention, the number of cylindrical segments in a set can be varied to adjust the length of the roller, the location of the segments on the roller can be changed to minimize wear, and damaged or worn segments can be replaced without having to replace an entire roller. The use of cylindrical segments having a relatively large diameter provides satisfactory operation at lower roller speed, better visibility for the operator, greater surface contact for the gripping of tassels, and a wider channel that leads to the detasseling nip.
