Abstract
An apparatus (10) for welding materials has a flat anvil (12) having a width of at least two inches and a length of at least eighteen inches. A welding apparatus (14) having at least one welding head (22) is mounted on a rail (16) which is parallel to said anvil (12). The apparatus (10) may be mobile. In an illustrated embodiment, welding apparatus (14) is an ultrasonic welding unit, and apparatus (10) is used to weld thermoset materials. As illustrated, the method is used to weld thermoset plastic monofilament fabric (34) to provide a continuous method of treating the monofilament fabric (34).
Claims5
An apparatus for spot welding a tabby of woven material to parallel synthetic or thermoplastic cords or monofilaments oriented longitudinally, the apparatus comprising:
- a flat anvil which is at least two inches (5.08 cm) wide and at least eighteen inches (45.7 cm) long;
- a welding apparatus including a welding head inclined diagonally relative to the longitudinally oriented synthetic or thermoplastic cords or monofilaments;
- a frame for mounting the anvil;
- a rail mounted to the frame and parallel to the anvil, the welding head being attached to the rail and movable on said rail;
- and
- wherein the welding head can be raised or lowered to provide diagonal spot welds at an angle to provide about four welds per each cord to the tabby.
