Abstract (en)
[origin: US5524678A] A leno selvage device for a loom has a leno rotor ring (7) which is directly driven by its own reversible electric motor, for example, through a power transmission such as a gear belt (6) running around a drive gear pulley (5). The controllable electric motor (20) is operated through a respective program for either oscillating the leno rotor back and forth, e.g. through 180 DEG or for revolving the leno rotor for a number of revolutions in one direction and then for the same number of revolutions in the opposite direction and so forth. The arrangement is such that the central rotational axis (5A) of the drive pulley (5) and the central rotational axis (7A) of the leno rotor ring (7) are positioned in different geometrical planes relative to a carrier arm (2), but in parallel to each other and to the weft insertion direction. The carrier arm (2) provides a plurality of bearing rollers which support the leno rotor ring or disk (7) at the outer circumference thereof by at least two, preferably three guide rollers.
