Abstract
A system for making self-supporting scrim is described. The apparatus includes a net forming means in which scrim yarns are arranged in overlapping pattern such as a criss-cross net; a net carrier and support for continuously advancing the criss-cross yarn net along a path; an adhesive supply means positioned along the path for applying an adhesive onto the advancing yarn net between the criss-cross yarns; and, an adhesive setting means positioned along the path for advancing the yarn net along the path while maintaining the individual yarns of the net substantially immoveable with respect to one another until the adhesive sets. In a preferred embodiment of the invention the adhesive setting means includes a pair of endless belts which engage surfaces on opposite sides of the yarn net so as to apply sandwiching pressure to the yarns and to advance the net. The various aforesaid means are inter-connected in series which together result in continuously stringing or arranging the yarns in a criss-cross or overlapping pattern, applying adhesive between the criss-cross yarns, and carrying the overlapped yarns from the adhesive supply means through the adhesive setting means to a finished scrim accumulator.
