Abstract: In a packaging apparatus, when replacing a preceding single-faced corrugated fiberboard (wrapping material) with a subsequent single-faced corrugated fiberboard, a draw-out roller is operated such that the preceding single-faced corrugated fiberboard is drawn out to its trailing end. At this time, a reserve roller, around which the single-faced corrugated fiberboard is trained, is moved such that the single-faced corrugated fiberboard, which has been drawn out, is accumulated thereat. Then, the trailing end of the preceding single-faced corrugated fiberboard and a leading end of the subsequent single-faced corrugated fiberboard are joined together at a joining device. In this way, the preceding single-faced corrugated fiberboard can be used up until its final end, and thus there is no waste of the single-faced corrugated fiberboard.
