The invention discloses a cloth inspecting method. A winding device, an unwinding device, a tensioning device and a cloth inspecting device are included. The winding device comprises a first winding roller, a second winding roller and a driving mechanism. The driving mechanism is used for simultaneously driving the first winding roller and the second winding roller to rotate discontinuously. The driving mechanism drives the first winding roller to rotate clockwise to conduct winding, the second winding roller stays still so that inspecting work can be conducted on cloth arranged on the secondwinding roller, when a driving wheel rotates anticlockwise, the second winding roller rotates anticlockwise to conduct winding, and the first winding roller stays still so that inspecting work can beconducted on cloth arranged on the first winding roller. Thus, the first winding roller and the second winding roller can conduct intermittent winding at the same time, so that the cloth inspecting work is facilitated.
