摘要
In the present invention, an air flow controller is disposed adjacent to an upstream side of an entrance of a tenter oven and/or a downstream side of an exit of the tenter oven. The air flow controller includes a box-shaped body cover that extends in a film running direction and has a surface facing a film running surface and being open. The box-shaped body cover includes at least one partition structural body extending in a film width direction inside the box-shaped body cover. The partition structural body separates the box-shaped body cover into a plurality of chambers. Air discharge mechanisms included in at least two of the chambers discharge air to the outside.
