Abstract
The device for cutting textile material and sealing the edges of the cut material comprises a heated resistance wire of round cross section supported in a supporting means. The wire forms a flattened central portion shaped to form a semi-circular bow having a symmetrical shape with a curved outer edge ground to a feather cutting edge, an inner edge and two lateral flat faces parallel to each other along which the edges of the textile material are moved after being cut by combined mechanical and thermal action of the wire. The edges of the textile material are sealed thereby. Since the temperature of the wire can be kept relatively low, no ridges of melted material are formed along the edges of the textile material.
