Abstract: A device for transmitting motion between the rotor of a synchronous permanent-magnet motor and the working part, having an increased free rotation angle, which comprises at least two motion transmission couplings which mutually cooperate in a kinematic series. Each coupling is constituted by at least one driving element which is eccentric with respect to the rotation axis and is rigidly coupled to a first component of the motion transmission system and by at least one driven element, which is also eccentric with respect to the rotation axis and is rigidly coupled to the component arranged kinematically after the preceding one. The angle covered by the elements of each coupling is, as a whole, less than a round angle. The intermediate components of the kinematic transmission have both a driven element and a driving element for receiving the motion from the preceding one and transmitting it to a subsequent one.

Abstract: The invention relates to an abrasive-supporting head for honing machines comprising an assembly which rotates around a vertical axis which is substantially perpendicular to the plane of arrangement of a slab being worked. The rotating assembly supports a plurality of abrasive-supporting elements which oscillate around axes arranged radially with respect to said vertical axis. The abrasive-supporting head furthermore comprises a three-dimensional bucket cam which engages with bilateral continuous contact rollers which are moved by said cam with a harmonic motion of the sinusoidal type for the oscillation of each abrasive-supporting element.

Abstract: A full-width scouring station particularly for delicate printed fabrics is described which comprises, within an outer housing, a tank containing a scouring liquid, at least one rotating drum, and a plurality of spray nozzles located above said drum and adapted to direct scouring liquid jets on a fabric resting on the drum, pumping means for supplying the scouring liquid to the spray nozzles and a drive means for rotating the drum.
