The cutting line (10) comprising an inner core (12) covered by an outer skin (14) has the skin made from a material with a higher melting point than the core to prevent adhesion, especially caused by friction. The cutting line (10) comprising an inner core (12) covered by an outer skin (14) has the skin made from a material with a higher melting point than the core to prevent adhesion, especially caused by friction. The core's melting point is between about 190 and 220[deg]C, while that of the skin is between about 250 and 300[deg]C. The thickness of the skin is between about 5 and 25 per cent of the line's mean radius. The line has a typical diameter of 1.2 to 5 mm and can be made with circular or other cross-sections. |
