To provide an efficient method for recovering wastes in a weaving machine with warp openings arranged in series.

A system in which wastes 1, 2, 14 and 10 from plural weaving machines are recovered in one part and transported to recovery lines 11 different or the same corresponding to the materials of the wastes is provided. A fly 10, a weft waste and the wastes 1, 2 and 14 are individually separated so as to transport these wastes by air flow in each batch. These batches are transported to the different recovery lines 11 by conveyors 8 and 9 placed at fixed positions by using an air flow 12 as a transporting means. Consequently, the objective ideal waste recovery method not requiring a change every time woven fabrics are changed is provided.
