Apparatus for producing reinforced plastic sheets and reinforced plastic sheet laminate structures on a high speed continuous basis and which sheets and laminate structures may have widths ranging from relatively narrow to very wide. The apparatus comprises a means for bringing one or more layers of resin impregnated, fiber-containing, reinforced plastic composite material into contact with each other or into contact with surfaces of one or more endwise abutted relatively flat panels.

An apparatus for producing a reinforced plastic composite article on a continuous basis, comprising: (a) means for continuously feeding through said apparatus a plurality of endwise abutted panels with each having a pair of spaced apart first edges and a pair of spaced apart second edges and relatively flat opposite surfaces; (b) winding means for winding a plurality of first strands of fiber reinforcing material about said panels in a direction which is at an angle to the direction of movement of said panels and which strands are in closely spaced relationship to one another about and around said pair of spaced apart first edges and across said relatively flat opposite surfaces, and where portions of said first strands extend across and between flat surfaces of two endwise abutted panels; and (c) means for applying a plurality of second strands of fiber reinforcing material to the first strands on said relatively flat opposite surfaces of said panels and extending between the spaced apart second edges with a predetermined amount of tension on said strands and while said panels are continuously feeding through said apparatus, and where portions of said second strands extend across flat surfaces of two or more endwise abutted panels, said plurality of first strands and plurality of second strands having been impregnated with a curable binder which was cured and bonded to first and second strands and thereby bonding said first and second strands to one another to effect a woven strand sheet and to bond same to said panels.
