Apparatus for forming rigid web-reinforced composites

Claim 1

Apparatus for forming rigid web-reinforced extruded composites comprising: an extruder having an extrusion die conforming in shape to a pair of said composites joined in mirror image relationship to each other, web supply means for feeding a pair of reinforcing webs into said die in spaced parallel relationship, supply means for feeding a curable elastomeric material into said extruder, a curing station positioned adjacent the output end of said die along the path of travel of the pair of extruded composites, a slitting knife positioned along the path of travel at the point of division between the pair of extruded composites to cut the elastomeric material and to separate the same into individual composites by continuous longitudinal splitting, drive means engageable with the edge portions of said reinforcing webs to draw said webs from the web supply means, through said extruder die, and past said slitting knife, and cutting means positioned at the end of the path of travel of the extruded composite for periodically cutting both of said pair of extruded composites to finished lengths wherein indexing notches are provided along the peripheral edge of said reinforcing webs to activate said cutting means at desired intervals.
