A fabric is made up of at least two laps (20, 21), each of which is formed by a series (22, 24) of longitudinal threads of yarn that are interwoven with one or more series (23, 25) of threads of yarn transverse to these. The first (20) and second laps (21) are joined along a common interweave stretch (30), respectively, parallel to the threads of warp yarn (22, 24) or parallel to the threads of weft yarn (23, 25) and in which the threads of weft yarn (23, 25) and of warp yarn (22, 24) of the two laps (20, 21) are interwoven. The common interweave stretch (30) extends laterally to the laps (20, 21) in such a way as to form a sort of third lap of width at least sufficient to guarantee the solidity of the join of the laps (20, 21) along the stretch of joining (30).
