<p>At industrial sewing of knitted fabrics e.g. for T-shirts, dresses and skirts, the problem exists that the edges of the fabric curl so that they cannot be sewn directly on a sewing machine. Prior to entering under the pressure foot (17) and becoming sewn the edges can be uncurled by a device which preferably comprises two counter driven smooth rollers (7a, 7b) placed in connection with the pressure foot of the sewing machine at the feeding end of the fabric and at an angle transversely to the pressure foot. If the edges of two pieces of fabric curl towards each other then the fabrics are guided at each side of the rollers, and if they curl away from each other then the fabrics are guided between the rollers.</p> |
