ABSTRACT:
A method and apparatus characterized by slitting a sheet of material having a natural resilience into a plurality of strips to form a body of such strips and folding each of the strips into a zig-zag shape. The folding step/function is accomplished by advancing the plurality of strips against a restriction acting on the body of strips in such a manner that the natural resilience of the material produces substantially uniform adjacent opposite folds thereby causing each of the strips to assume a zig-zag shape.
