THE METHOD FOR MAKING NON-WOVEN, CRISS-CROSS STRAND NETTING OF A PREDETERMINED FULL WIDTH ON A PAIR OF LATERALLY, SPACED APART ROWS OF LONGITUDINALLY SPACED, LOOP-RECEIVING ELEMENTS WHICH DEFINE A LONGITUDINAL PATH FOR SAID NETTING WHICH COMPRISES THE STEPS OF: ADVANCING SAID ROWS UNIDIRECTIONALLY, EACH IN A CLOSED LOOP AND BOTH IN A COMMON PLANE THROUGH A LOOPING ZONE, A SPREADING ZONE, AND A STRIPPING ZONE ON SAID PATH; CLOSELY SPACING SAID ROWS IN PARALLELISM AT A DISTANCE APART, SUBSTANTIALLY LESS THAN SAID FULL WIDTH IN SAID LOOPING ZONE ON SAID PATH; ALTERNATELY LOOPING A PLURALITY OF INDIVIDUAL STRANDS FIRST AROUND ELEMENTS IN ONE SAID ROW AND THEN AROUND ELEMENTS IN THE OTHER SAID ROW, WHILE SAID ROWS ARE CLOSELY SPACED IN SAID LOOPING ZONE, T FORM A RELATIVELY NARROW CRISS-CROSS NETTING THEREBETWEEN; THEN DIVERGING SAID ADVANCING ROWS, IN REAR OF SAID LOOPING ZONE, IN SAID SPREADING ZONE ALONG SAID PATH, UNTIL THEY ARE SPACED APART THE FULL WIDTH OF THE SAID NETTING; AND THEN CONVERGING SAID ADVANCING ROWS IN REAR OF SAID SPREADING ZONE, IN A STRIPPING ZONE ALONG SAID PATH UNTIL SAID ROWS ARE AGAIN IN PARALLELISM AT A DISTANCE APART SUBSTANTIALLY EQUAL TO THE SAID PREDETERMINED WIDTH OF SAID NETTING.
