Patent ID: 7770417

Claim:
A selection device for hosiery knitting machines or the like, wherein it comprises a magnetic actuator according to one or more of the preceding claims, with said at least two poles of the main magnet arranged sequentially along an actuation direction and selection elements which can be attracted magnetically and can move along said actuation direction with respect to said selection actuator in order to face sequentially a first one of said poles of the main magnet, then said discontinuity and said at least one pole of the selection electromagnet and then a second one of said at least two poles of the main magnet; said selection elements being movable from a first position, in which they are kept adjacent to said poles by the magnetic attraction applied by said poles, to a second position, in which they are further spaced from said poles with respect to said first position; said coil being suppliable with electric power in order to keep each selection element in said first position or allow the passage of each selection element from said first position to said second position upon its passage at said discontinuity and at said at least one pole of the selection electromagnet.
