A device for automatically changing cops in a loom and particularly in a ribbon loom having one or more shuttles and a slay positively driven by a loom main shaft. Said device comprises at least a presser by which a stored full cop is driven to a shuttle seat, wherefrom an empty cop is ejected, said presser being directly and positively driven by a slide link secured to the slay. The operation of said device is pre-set in a preceding shuttle stroke by means of an electric circuit that is closed through the shuttle carrying said empty cop to be replaced, when its weft yarn is substantially woven-off.
