ABSTRACT:
The loom includes a reed constituted by a plurality of blades which are in alignment and parallel to each other. These blades have respective substantially circular apertures which have the same diameter and are aligned with each other to form a straight passage for guiding the pneumatic insertion of the weft. The portion of each blade between the aperture and the side of the blade facing the fabric (T), in use, has a substantially horizontal slit which extends from the aperture to the side of the blade. Between each pair of adjacent blades are interposed first and second spacer elements which are arranged respectively above and below the aperture and the slit of the blade. The loom includes drive means which, when activated, cause translational movement of the reed perpendicular to the longitudinal axis of the passage formed by the apertures in the blades of the reed.
