A METHOD OF SEPARATING PREDETERMINED LENGTHS FROM A CONTINUOUS TUBE OF FLEXIBLE MATERIAL, WHICH TUBE IS WEAKENED ALONG A LINE EXTENDING TRANSVERSELY AROUND THE GREATER PORTION OF ITS CIRCUMFERENCE AT SPACED INTERVALS CORRESPONDING TO SAID PREDETERMINED LENGTHS BUT IS INTEGRAL AND UNWEAKENED ALONG A LONGITUDINALLY EXTENDING PORTION THEREOF COMPRISING, PASSING SAID TUBE ALONG A PATH OF TRAVEL INCLUDING: (1) A STRAIGHT-LINE PATH WHEREIN SAID TUBE MOVES CONTINOUSLY AND SAID TRANSVERSE WEAKENED LINES REMAIN CLOSED; (2) A LATERAL PATH SPACED FROM SAID STRAIGH-LINE PATH WITH SAID UNWEAKENED PORTION ON THE INSIDE THEREOF WHEREIN SAID TUBE MOVES INTERMITTENLY AND A V-SHAPED SPACE IS OPENED BETWEEN THE FOREMOST PREDETERMINED LENGTH AND THE REMAINDER OF SAID TUBE, THE UNWEAKED PORTION AT THE APEX OF SAID SPACE REMAINING STATIONARY FOR A TIME INTERVAL DUE TO THE INTERMITTENT MOVEMENT OF SAID TUBE IN SAID LATERAL PATH; AND (3) A PATH AT AN ANGLE TO AND BETWEEN SAID STRAIGHT LINE AND LATERAL PATHS VARIABLE WITH LIMITS WHEREIN THE CONTINUOUS MOVEMENT OF SAID STRAIGHT-LINE PATH CHANGES TO THE INTERMITTENT MOTION OF SAID LATERAL PATH, INSERTING A CUTTING ELEMENT INTO SAID SPACE AND SEVERING SAID UNWEAKENED PORTION AND REMOVING SAID ELEMENT FROM SAID LATERAL PATH WHILE SAID UNWEAKENED PORTION IS STATIONARY, AND SEPARTING THE COMPLETELY SEVERED LENGTH FROM SAID TUBE.
