ABSTRACT:
A tenter system designed to be used for simultaneously treatment of two base fabrics for felts for paper machines, or similar products, an upper fabric (3) and a lower fabric (4), comprising a pair of tenter frames (6) for the upper fabric and a pair of tenter frames (7) for the lower fabric being adapted to grip respectively the upper and lower fabric along both edges of the fabrics through the heat treatment zone (5), and to maintain specified stretch in the direction transversally to the direction of fabric movement by allowing the two pairs of tenter frames (6, 7) to move in the transversal direction independently of each other, thereby allowing independent change of width of the two fabrics in the transversal direction.
