Abstract

PURPOSE:To prevent the unevenness of the cut lengths of fruit stems and the slant cutting of the stem, by attaching a pair of aligning plates to a fruit supporting table of a conveyor, and carrying out the longitudinal and transversal alignments of the stem at the same time. CONSTITUTION:A fruit (B) is set on the holding bed 2a of the fruit supporting table 2. When the fruit stem (b) and the neck part (c) of the bag (C) fixed to the stem (b) with the fastener (D) are deviated from their correct positions along the direction of the conveyor or the transversal direction, the oppositely placed aligning plates 8,8 are closed to effect the intermeshing of the notched parts 81, 81. The stem is shifted longitudinally or transversally by the slant edges of the notched parts 81, 81 toward the center of the holding bed 2a. The longitudinal and transversal deviations of the stem are corrected at the same time by this operation, and the stem is held with the stem-holding and transferring device. By the above process, the angle of the stem is maintained to a definite state, and the cut length and the cut angle become uniform.
