A method for preparing a fibrous laminated strip on an elongated supporting surface, using a continuous fiber shredding apparatus having X shredders each cutting and applying P fibers/min., the strip consisting of N laminated layers of shredded metal fibers having a total weight per unit area of W gr./in2, the fibers having a thickness of f1 in., a width of f2 in. and a density of d gr./cu. in., the fibers of each layer being disposed at an orientation angle theta from the longitudinal axis of the supporting surface; the method comprising the steps: (1) forming a layer having a weight per unit area of w gr./in2 by applying P fibers/min. on the elongated supporting surface in a longitudinal direction, the fibers being disposed substantially parallel to each other and at an angle theta of between 15 DEG and 75 DEG from the longitudinal axis of the elongated supporting surface, the fibers being applied to the supporting surface at a traverse speed of Q in./min. and then (2) forming N layers by applying, at a speed Q, additional layers of loose thin metal fibers substantially parallel to each other within a layer, to cover the previous layer at an angle from the longitudinal axis of the elongated supporting surface alternating between theta and theta ' where theta ' = theta wherein the following relationship exists:
