To uniformize the interlace bonding between a base fabric and a nonwoven fabric layer at a joint part, maintain the surface character of the joint part at a high level equivalent to that of a needle canvas body through preventing joining loops from deformation and elongation, and to raise the rigidity of the joint part.

The objective joint is characterized in that at the end of the base fabric 10 of 2.5-fold weave design comprising warps 11, wefts 12 (13 and 14) and wefts 15 as an intermediate layer, loops 20 are formed by folding back the warps 11 and additional wefts 21 are woven-in among the wefts 15 as the intermediate layer to make a triple weave design 50, and a single equivalent of the wefts (14) is each woven in the base fabric body side and the joint end side from each of positions 31 facing on the end of extending warps 32 on the joint end side and the end of extending warps 33 on the base fabric body side to effect interlacing the nonwoven fabric layer 60 on at least contact paper surface side.
