If, on the other hand, the warps P had been called at the point i n the weave indicated in Fig. 1 there would have been a long stretch of pile warp P, which would have crossed the filling between the filling shot 23 and the filling shot 24 and closely adjacent the latter. When the fabric was beaten up, the long stretch of pile warp P would have caught and held the filling and wouldt-have caused f it to be beaten up therewith. As the filling shot 24 is much nearer thefill'ing 'shOtQBafter beating up, this operation wouldproduce surplus filling between the'points 23 an d 24 which surplus must necessarily fQlfl n aLl-oose bend or loop at the edge of the selvage. The formation of these loose bends orloop s at the selvage is effectively avoided inmy improved weave, as above described;

The phrase each having a full setof pile warps therein? asusedin the claims indicates thatthe upper fabric has a full and, complete set of all of the kinds or colors ,of warps used to produce the double fabric and that the lower fabric has an identical but, separate complete setof,war;ps.,
