WELDING Welding is the performed by high-frequency presses and electrodes placed according to the drawings. The C.B.M. kits allow side conveyor or restraining V-guides - up to 2.000 mm long - as well as sidewalls and transversal profiles in several sizes to be fixed. They can also be welded on belts supplied with either V-guides or edges. Many other types of applications are also available, such as open or closed vertex herringbone, arcuated profiles, simple or double-rabbet negative-rake profiles, fingers and marble pits.
