Abstract:
1. A triple pass tunnel fabric finishing apparatus, comprising: a conveyor having a serpentine conveyor path; a first, a second, and a third linear tunnel arranged in a continuous, side-by-side manner and defining a portion of the serpentine conveyor path, the tunnels defining a first U-turn of the conveyor path at an entrance to the first tunnel, a second U-turn of the of the conveyor bath between an exit of the first tunnel and an entrance of the second tunnel, and a third U-turn of the conveyor path between an exit of the second tunnel and an entrance of the third tunnel, wherein said U-turns provide a curved pathway while conveyor paths though the first and the third tunnels are generally parallel and a conveyor path through the second tunnel is generally anti-parallel to the conveyor paths through the first and the third tunnels; a steam injector disposed in the first linear tunnel and positioned adjacent an outer curve of the first or second U-turn; and a hot air chamber disposed in at least one of the second and third linear tunnels.
