High speed automatic machine for side-cut cable and standard cable chain. The side-cut chain is particularly suitable to be combined with Bismark machines with more than one row, avoiding powder welding (necessary with traditional machines), with remarkable advantages as far as the uniform chain pitches, the saving on the productive cycle and the guarantee of the karat are concerned. The motorpowered base, the electronic speed regulator, the patented rotating head centering device, the synchronized air blower and the led lamp complete the current equipment of the machine.
