ABSTRACT:
An electromechanical actuator device for a sewing machine is described.
The main feature of said device is that it comprises a plurality of electromagnets, each of which is arranged to be put into either a rest state or a working state, depending upon a respective electrical feed signal; at least one actuator member connectable to a fabric conveying foot in the said sewing machine and arranged to assume either a rest position or a working position corresponding respectively to said rest state or working state of each of said electromagnets; a plurality of mechanical coupling means disposed between said plurality of electromagnets and said actuator member, and a drive shaft which is actuated by means of a power take-off and actuates the said mechanical coupling means; each of said mechanical coupling means being arranged to be put either into a respective rest position or working position, depending on the state of a corresponding electromagnet, and to mechanically set said actuator into either said rest position or working position.
