ABSTRACT:
A double-clutch coupling for looms, which comprises a first controllable clutch coupling a drive shaft connected to a first member of the loom to a driven shaft connected to a second member of the loom, movable in synchronism with the first and coaxial with the drive shaft. A second controllable clutch couples the driven shaft to an auxiliary motor device. The clutches are equipped with respective actuating electromagnets acting in opposition to springs. The clutches each comprise an annular electromagnet rigidly connected to a fixed support shell inside which the drive shaft and driven shaft are supported with their axes in a fixed position. The electromagnet is at least partly contained by a rotor axially fixed with respect to it and linked with the magnetic flux generated by the electromagnet itself when it is energized. In front of each rotor there is an annular armature, axially movable under the action of the magnetic field generated by the relevant electromagnet in opposition to the spring. The armatures are rotatably locked respectively to the drive shaft and driven shaft and carry the movable members of the clutches.
