PURPOSE:To improve accuracy of zigzag folding by creasing a baseboard tape sticked with electronic parts then feeding the baseboard tape through a classifying means to radial rotary vanes and folding the baseboard tape. CONSTITUTION:A baseboard tape 1 sticked with electronic parts and fed from upstream is creased alternately through a folding machine 6, then fed through a baseboard feed roller 7 to a classifying unit 8 in a guide box 3. The classifying unit 8 comprises a classifying guide 9 and a swivel table 10 which is rotated to the right or left through a rotary actuator so as to swing the baseboard 1 to right and left fixed guides 13. The baseboard 1 contacts with impellers 4, 5 having a pair of radial rotary vanes, and folded while being held by upper and lower vanes 4a, 4b and 5a, 5b then guided to the rear of the guide box 3 and stacked therein. Consequently, the baseboard can be folded in zigzag through simple structure.
