ABSTRACT:
A tentering oven comprises a heating furnace and a tenter. The heating furnace has multiple plenum ducts juxtaposed above and below a film in a direction perpendicular to the flow of the film for blowing hot air to heat the film. The tenter stretches the film transversely and comprises clip bodies, clip levers and liners provided on linked chains, as well as rails composed of chain directing rail members that progressively depart away from each other and a chain drive member. An oil pan is provided beneath a joint of the rail members and each of the plenum ducts is provided in such a way that the hot air discharge port of the ducts is not positioned immediately below the oil pan so as to ensure that the hot air blown from the plenum duct does not make direct contact with the bottom of the oil pan.
