Abstract
An oven 1 includes a nozzle module 4 which is constructed such that a plurality of nozzle units 6 are alternately connected to an opposing pair of air chambers 5 arranged on the opposite sides of a conveyor 2. Each nozzle unit 6 has an upper nozzle 10 and a lower nozzle 11 both of which base end sides are pivotally supported to turn about support shafts 13 and 15 and of which foremost end sides are operatively supported by opening/closing units 16. Each opening/closing unit 16 has an elongated flexible member 17 suspended from a sprocket 18, and the opposite ends of the elongated flexible member 17 are operatively connected to the foremost end sides of the upper and lower nozzles 10 and 11. As the sprocket 18 is rotated, the upper and lower nozzles 10 and 11 are turned in the upward/downward direction, whereby each nozzle unit 6 is opened or closed in the vertical direction. A radiator 7 is arranged on the conveyor 2 side relative to each air chamber 5 while extending in the vertical direction.
