Abstract: A reed monitoring assembly to monitor a weaving reed that have dents juxtaposed along longitudinal direction of the weaving reed. The dents define height direction of the reed and reed gap. The assembly includes an optical device with a first camera array, for taking images of a first portion of the weaving reed, and facing the first longitudinal side of the weaving reed, an illumination device to illuminate the first portion of the weaving reed, and a second camera array, for taking images of a second portion of the weaving reed, and facing the opposite longitudinal side of the weaving reed. The reed monitoring assembly also includes a controller, for controlling the optical device and for receiving image data from the device, and mounting means allowing a relative movement between the weaving reed and the optical device, along an axis parallel to the longitudinal direction of the weaving reed.
