Abstract: An improved loom of the shuttleless type, which comprises for each weft inserter a magnetic guiding device mounted in the slay of the loom and having a ferromagnetic core, of elongated shape, with a coil wound longitudinally around the core. A pair of plates is engaged longitudinally on the opposite sides of the core and laterally delimiting the coil. The plates are positioned in planes perpendicular to the upper base of the slay and face a direction parallel to the direction of motion of the weft inserters. There are also provided a pair of non magnetic spacing plate members placed between the plates so as to define together with the plates themselves a rectangular housing within which is enclosed said coil. The plates thus define with their edges past the spacing plates, as the current passes through the coil, a magnetic guiding path within which run the weft inserters moving over the slay of the loom.
