Weaving device and method capable of changing warp and weft density on line

The invention provides a weaving device and method capable of changing warp and weft density on line. The device comprises a weft density on-line changing mechanism and a warp density on-line changing mechanism. The weft density on-line changing mechanism comprises a first single-chip microcomputer, and the first single-chip microcomputer is connected with a control panel of a weaving machine. The warp density on-line changing mechanism comprises a variable density reed, a transmission control device and a second single-chip microcomputer. The variable-density reed is connected to a sley of the weaving machine through the transmission control device, and the transmission control device is connected with the second single-chip microcomputer. According to the weaving device and method capable of changing the warp and weft density on line, cloth with different warp and weft densities in different areas can be woven, and the weaving device and method can be used in some occasions with special requirements. 本发明提供一
