Jacquard device to selectively shift thread guides in a textile machine

A jacquard device (1) for selectively shifting thread-guides (2) in a knitting machine, comprising:

• at least one supporting element (3) provided with a plurality of housing seats (4) for a plurality of thread-guides (2), said supporting element (3) being a thread-guide bar of jacquard type for a warp linear knitting machine and being moving with respect to at least one bed (5) of needles (6) for selectively feeding the needles (6) of said bed (5) with a thread (7),
• a plurality of thread-guides (2) having each at least one mounting seat (2a) where they are fixedly mounted onto said supporting element (3), and at least one thread-guide portion (2b) selectively moving at least between a first and a second operating position and apt to guide said thread (7);
• at least one actuating element (12) operatively acting upon at least one of said thread-guides (2) for shifting said thread-guide portion (2b) of said thread-guide (2) between said first operating position and at least said second operating position;
• characterized in that it further comprises:
• at least one electropneumatic actuating device (15) operatively connected to said actuating element (12) for shifting said actuating element (12) and thus said thread-guide portion (2b) of said thread-guide (2) between said first and said second operating position.
