Form fixing machine particularly for wool fabrics

摘要

The fixing machine comprises a fabric impregnation/wringing area (30) and a form fixing area (40). Such area (40) includes a heated rotating metal drum (6) and a first form fixing endless back piece (7) of rubber material concordantly rotatable with the drum (6) and having an operational portion 31 partially trained about drum (6) and pressed against a fabric made to pass between drum (6) and first back piece (7). A second closed-ring back piece (8), substantially not yielding to traction, is arranged with an operational portion (32) thereof pressing against portion (31) of piece (7) with a predetermined pressure higher than of piece (7) against the fabric and metal drum (6). The exit extremity of portion (32) of piece (8) is further back with respect to the corresponding extremity of portion (31) of piece (7) so as to impart to the fabric a sharp temperature reduction which stabilizes the form attained.
