Abstract
Abstract A loom having a deflection beam at the side of the warp for the warp ends and a deflection beam at the side of the cloth for the woven cloth, the deflection beams essentially delimiting the weaving plane containing the shed forming mechanism and the reed. A cover arrangement extends only above the weaving plane essentially from the deflection beam at the side of the warp up to the deflection beam at the side of the woven cloth.
