ties 50 and 60 located closest to the web edges 40 and 42 an expanded puckering action concentrates the tensile forces 78 through these remaining ties 50 and 60 resulting in their rupture and a complete separation of scrip sheet 12 a from the scrip sheet 12 b as shown in fig3 d although all of the ties 50 52 54 56 58 and 60 can be initially stressed by the tensile forces 78 applied along the centerline 38 the relative weakening of the centermost ties 54 and 56 together with a controlled distortion of the web 14 permits the tensile forces 78 to break the remaining ties in a succession of tie pairs 54 and 56 52 and 58 and 50 and 60 the breakage of the ties 50 52 54 56 58 and 60 in the prescribed succession significantly reduces the overall magnitude of the tensile forces 78 required to separate the scrip sheet 12 a from the remaining portion of the web 14 with respect to the overall magnitude of the tensile forces required to achieve the same objective by breaking all of the ties 50 52 54 56 58 and 60 at once the overall magnitude of the tensile forces 78 is comparable to the overall magnitude of tensile forces 80 applied manually along the edge 40 of the web for rupturing the ties 50 52 54 56 58 and 60 according to a more conventional tearing action depicted in the drawing fig4 a 4d here the tearing begins at the tie 50 located closest to the edge 40 and proceeds one by one through the remaining ties in their listed order 52 54 56 58 and 60 without regard to the relative strengths of the ties.
