Abstract: A method and device for making a weft of a weaving for wigs is disclosed. The method and device makes the weft mechanically, thus uniformly forming wig strands supported by the weft. Both the wig strands, forming the warps of the weaving, and the weaving yarns, forming the weft of the weaving, are made of the same material, such as human hair or synthetic resin material, so that there is no heterogeneity between them and this allows wearers of wigs to have a soft and comfortable feeling. Such weft is made by using an automatic machine without applying any bonding agent on the weaving or sewing the weaving using a sewing machine. Therefore, wigs can produced in commercial quantity while conserving labor cost.
