<p>A control mechanism of a heald frame in weaving looms is disclosed, of the type comprising a frame hinged to an articulated linkage capable of converting the substantially rectilinear motion of a control bar (B) into a vertical motion of the frame, characterised in that said bar (B) is provided with a permanent magnet body (M) and in that an electric-coil structure (C) is further provided, in whose proximity said magnet body (M) is intended to slide, fixed in respect of the loom and forming the armature of a linear electric motor of which the magnet body (M) represents the mobile part. Some preferred arrangements of a plurality of such mechanisms in a weaving loom are further disclosed. <IMAGE></p> |
