Abstract A system for preparing an elongated laminated strip having a plurality of layers of metal fibers with the fibers of each layer being disposed at angles to the fibers of adjacent layers, including at least two fiber cutting shredders which are mounted on a movable carriage above a conveyor belt. The movable carriage travels back and forth over a short segment of travel of the conveyor belt and the shredders are rotatably mounted on the carriage for dropping successive layers of metal fibers onto the conveyor belt with the fibers of each layer being disposed at angles to each other. At the end of travel of the carriage in each direction the shredders are rotated to different angles and the belt simultaneously moves a short increment of travel, whereby a continuous multiple layered strip of metal fibers is produced. At another work station on the belt an adhesive binder is applied to the strip so that upon leaving the belt the strip may be wound upon a reel for storage and handling.
An apparatus for preparing a laminated strip of layers of metal fibers with the fibers of each layer disposed at an angle to that of an adjacent layer, comprising a conveyor belt, a carriage alternately movable in forward and reverse directions of the direction of travel of the belt, at least one shredder of metal foil being mounted on the carriage, the shredder being rotatable on an axis perpendicular to the plane of the belt, means for rotating the shredder between two positions at angles to each other and operable at the end of travel of the carriage in each direction, means for moving the belt at segmental distances synchronized with the end of travel of the carriage in each direction, whereby one layer of fibers is layed at one angle on the belt as the carriage moves in one direction and another layer is layed at another angle on the one layer as the carriage moves in the opposite direction.
