Abstract:
A process for applying droplets of liquid in accordance with a predetermined pattern to a moving sheet of individual yarns arranged in spaced, parallel relation, said process comprising:(a) guiding a moving sheet of yarns along a pre-defined path, said sheet being comprised of individual yarns arranged in parallel relationship, with spaces between adjacent yarns;(b) indexing the movement of said moving sheet along said pre-defined path by generating signals corresponding to the advancement of said moving sheet along said pre-defined path;(c) correlating said signals with pattern data;(d) directing a spray of liquid droplets into said pre-defined path, thereby applying a first portion of said sprayed liquid to said spaced adjacent yarns comprising said moving sheet as said moving sheet moves along said pre-defined path, and projecting a second portion of said sprayed liquid through spaces between said spaced adjacent yarns;(e) collecting and recirculating said second portion of said liquid spray; and(f) pneumatically interrupting said spray of liquid droplets into said pre-defined path in accordance with said correlated signals, whereby said sprayed liquid droplets are applied only to select portions of said moving sheet in accordance with said pattern data.
