Reed monitoring assembly, drawing-in machine incorporating such a reed monitoring assembly and process for monitoring a reed with such a reed monitoring assembly

A process for monitoring a weaving reed with a reed monitoring assembly, said weaving reed having a first longitudinal side, a second longitudinal side opposite to the first longitudinal side, a plurality of dents juxtaposed along a longitudinal direction of the weaving reed and two reed profiles surrounding two ends of the plurality of dents, the plurality of dents defining a height direction of the weaving reed and, between each pair of two adjacent dents of the plurality of dents, a reed gap, the weaving reed defining also a transverse direction perpendicular to the longitudinal direction and to the height direction, wherein said reed monitoring assembly comprises a controller and an optical device comprising a first camera array and a second camera array, each camera array being formed of several optical sensors adjacent to one another and the respective fields of view of two adjacent optical sensors overlapping in the reed height direction and wherein the process includes at least the following steps:

• A) taking at least a first image of at least a part of each reed profile, a part of two dents of the plurality of dents and one reed gap in-between, on the first longitudinal side of the weaving reed, with the first camera array of the optical device of the reed monitoring assembly;
• b) taking at least a second image of at least a part of each reed profile, a part of two dents of the plurality of dents and one reed gap in-between, on the second longitudinal side of the weaving reed, with the second camera array of the optical device of the reed monitoring assembly;
• c) sending, to the controller of the reed monitoring assembly, image data corresponding to the first image;
• d) sending, to the controller of the reed monitoring assembly, image data corresponding to the second image;
• e) moving the weaving reed with respect to the optical device, along an axis parallel to the longitudinal direction of the weaving reed.
