ABSTRACT:
A method and apparatus for continuously weaving fibers or filaments, particularly glass fiber filaments, into a scrim cloth, to serve as reinforcement in the fabrication of filament reinforced foam insulation slabs. The scrim cloth consisting of uniformly spaced filaments in the X (longitudinal) direction and Y (transverse) direction is fabricated by traversing the Y filaments between hooks attached to long moveable oppositely spaced side panels and by paying off bands of spaced X filaments at various locations between the Y traversing mechanism. One layer of scrim cloth is fabricated at each station, the desired number of stations for the respective layers being located sequentially along the length of the machine. In fabricating a single layer of cloth at any station, a rotatable vertical tube through which a continuous Y filament is payed from a remotely mounted spool, is moved on a cross slide mechanism transversely back and forth between the hooks on the side panels of the machine, the filament from the lower end of the tube being initially tied to the first hook. The motion of the cross slide and an arm mounted on the rotatable tube orients the Y filament on one hook or set of hooks on one side panel as the cross slide changes direction, and after traversing the distance between the side panels the cross slide and arm on the tube orients the Y filament on an oppositely facing hook or set of hooks on the opposite side panel. The X filaments for each layer are inserted as a band of spaced filaments, each such X filaments moving in the direction of longitudinal side panel travel and resting on the Y filaments.
