摘要： PROBLEM TO BE SOLVED: To prevent tapes from being twisted or entangled when they are delivered from a packing box for use by achieving the packaging by alternately changing the direction of the rotational force to be given to the tapes while they are dropped into the packing box in the forward direction and the opposite direction at every specified number of revolution. SOLUTION: Tapes 1 are held and taken in by a pinch roll 2, and while the are passed through in a blow-off pipe 3 having a bent part, the rotational force in the forward direction or in the opposite direction is given to the blow- off pipe 3 by a drive pulley 7 to be rotated by the power to be transmitted from a motor 8 through a belt 9. The number of revolution for each change from the forward direction to they opposite direction, or vice versa, is at least one, preferably 3-6. The tapes 1 after passing through the blow-off pipe 3 having the bent part are dropped in an arc shape turning to the right or to the left between a center part of a packing box 4 and is side wall, and stacked.
