Apparatus for producing reoriented glass fibre material

Abstract From the Canadian patent

A method and apparatus for producing a fibrous material product by advancing a mat of glass fibers arranged in laminations extending at least substantially parallel to opposite major surfaces of the mat along a gap extending between successive driven conveyors which engage the opposite major surfaces of the mat to control the advance of the mat alone the gap, and driving the conveyors at progressively slower speeds along the gap so that the laminations are deformed in at least two separate stages into a reorientation in which at least a major portion of the laminations extend across the thickness of the mat. The resulting product has an improved compression strength.
