  • Patent number: 4265104
    Abstract: In a method for simultaneously cutting three continuous double-comb components from a metal strip the strip is moved forward stepwise. At each stop, a row of notches is made along each edge to form teeth and a row of crosses is removed from its central part, the crosses being made up of two portions of the central part and two teeth facing notches and separated therefrom by a portion of the central part. After the teeth have been bent, the comb-shaped components can be used to reinforce rubber packing or linings, more particularly in the car industry.
