  • Machine for producing aluminum foil sheets for hair coloring
    Patent number: 6602177
    Abstract: A machine for cutting and folding sheets of aluminum foil dispensed from a roll. The machine comprises means for mounting a roll of aluminum foil so that aluminum foil can be advanced through the machine. Two adjacent rollers can be electrically driven to advance aluminum foil by frictional force from the roll. The machine further comprises a knife mechanism for cutting off a sheet of aluminum foil after it has passed between the rollers and means for folding an edge of a cut sheet produced by the knife mechanism. A control unit for controlling the knife mechanism ensures that the aluminum foil is cut only during predetermined intervals.
