same manner as with the cross machine direction yarns 4 this enables the batt to be strongly anchored to the seam in addition the stuffers provide control over differences in the permeability and density between the seam area and the woven fabric fig9 and 10 illustrate the construction of fig8 with selected stuffers removed fig9 illustrates batt material 20 on the paper supporting surface only and fig1 illustrates batt material on both surfaces to place the woven fabric of the invention in service it is fitted around the usual cylinders with the terminal ends 17 and 17 39 of fig7 juxtapositioned the end loops 12 and 12 39 are then intermeshed to form the pintle channel 15 the free ends of respective loops abut the stuffers of the opposite end a pintle 13 is passed through the pintle channel 15 to interconnect the fabric ends although an optimum 90 u00b0 anqle at the loops 12 and 12 39 maximizes the advantages of the invention it is very difficult to obtain such complete control of the yarns in practice loops 12 and 12 39 which form a substantially vertical plane perpendicular to the horizontal plane of the fabric at about 90 u00b0 u00b1 15 u00b0 will provide the benefits of the invention with respect to actual construction of the fabric and the seaming loops it is recognized that the fabric may be flat woven and the seaming loops formed through known loop forming techniques or back weaving or that the fabric.
