It is positioned so as to overlap the center in the width direction, that is, the hole 23. In each of the side areas Q and R, approximately 50% of the area overlaps the film-like object F1. In this steady state, the air force from the side opening provided in the side region Q is balanced with the air force from the side opening provided in the side region R. The force of air from the holes 23 provided in the side regions Q and R acts on the film-like object F1 as a force for maintaining the steady state.

  On the other hand, as shown in FIG. 7D, the film-like object F1 that is conveyed while being levitated by the levitating conveyance device 10 has both ends in the width direction in the side regions Q and R in a meandering state for some reason. It is located so as to deviate from the center in the width direction. In each of the side regions Q and R, more than 50% of the region or less than 50% of the regions overlap the film-like object F1. For example, in the side region Q, about 80% of the region overlaps the film-like object F1, and in the side region R, about 20% of the region overlaps the film-like material F1.

Big in comparison. The air force as the entire side opening provided in the side regions Q and R acts in the direction from the side region Q to the side region R, that is, the direction in which the film-like object F1 returns to the steady state. This force increases as the deviation of the film-like object F1 increases, and decreases as it approaches a steady state. The film-like object F1 that has meandered in the direction of the side region Q returns to a steady state or further meanders in the direction of the side region R. The air force as the entire side opening provided in the side regions Q and R gradually decreases as the side region approaches the steady state, and finally returns to the steady state.

  When the film-like object F1 meanders in the direction of the side region R, the air force from the side opening provided in the side region R is the force of the air from the side opening provided in the side region Q. Big in comparison. The force of air as the whole side opening provided in the side regions Q and R acts in the direction from the side region R to the side region Q, that is, the direction in which the film-like object F1 returns to the steady state. The film-like object F1 that has meandered in the direction of the side region R returns to a steady state or further meanders in the direction of the side region Q. The air force as the entire side opening provided in the side regions Q and R gradually decreases as the side region approaches the steady state, and finally returns to the steady state.

  The force of air from the hole 23 provided in each side region Q, R is applied to the film-like object F1 as a force for preventing meandering in the direction of the other side region Q, R after returning to the steady state. Works.
