Abstract

A tenter frame for spreading and treating open widths of a moving fabric which includes a pair of endless tenter chains each of which has a plurality of upstanding pins adapted to engage opposed edges of the fabric for transporting the fabric through the tenter through a first generally horizontal plane. A feed roll is provided for guiding the fabric which has an upper periphery located in a second generally horizontal plane which is higher than the horizontal plane of the tenter chain. A static decurling apparatus is disposed along each side of the tenter frame at a point between the ends of the tenter chains and the feed roll and extends in a generally inclined plane which intersects the first plane and the second plane. The decurling apparatus contacts the edges of the moving fabric and removes the curl, folds and the like from the edges for guiding the fabric towards the tenter chains. Nip rolls are provided which have a nip in the horizontal plane of the tenter chain adapted to receive the moving fabric as it traverses through the decurling apparatus for maintianing the fabric edges in a flattened uncurled condition. An arcuate plane is disposed between the decurling apparatus and the nip rolls for generally bridging the distance between the nip rolls and the decurling apparatus.
