An automatic interlayer trimming assembly is provided with an abrasive belt that contacts the edge of a windshield assembly after lamination to remove any interlayer that has extruded out from the windshield edge during lamination. The belt is supported and advanced by a plurality of rollers and the windshield edge is moved in the same direction as the advancement of the belt. In addition, the belt may oscillate in a direction perpendicular to the belt advancement to help remove the interlayer.
