Abstract
An air injection nozzle has an air injection face with a number of air injection holes arrayed at an interval (Py) in first and second staggered rows. The first row and the second rows are positioned at an interval (Px). The air injection face and the sheet running face confront each other at a distance (L). The air injection holes in the air injection face have a diameter (D). The interval (Px), the interval (Py), the distance (L) and the diameter (D) satisfy Formula (1): 6≦(L/D)/(Px/Py)≦9, and Formula (2): 4≦L/D≦8. This air injection nozzle is employed as a resin film heat treating apparatus in a tenter oven to be used for manufacturing the resin film.
