Abstract: A device for automatically checking quality of a spool of thread for fabrics is provided. The device has at least one vision system provided with a camera, a frame of the camera defining an analysis area, the camera being connectable to a system for moving a spool of thread to be analyzed and to a computer having an analysis software stored thereon, and at least one lighting system having at least one pair of lights arranged facing each other and transversely in relation to the analysis area, each light of the at least one pair of lights having at least one light source for providing a sidelight to the analysis area.

Abstract: A device for automatic control of color tone of a reel of thread includes a frame supporting an arm on which a reel of thread is loadable, a meter configured to project a measuring beam onto a cylindrical portion of the reel of thread, the meter having a camera and an illuminator aligned with the camera, the illuminator being multispectral and configured to illuminate the reel of thread with different wavelengths. A computer provided with a screen with graphic interface and connected to the meter processes the classification of the reel of thread loaded on the arm on the basis of measurements performed by the meter.
