Needle loom with automatic change of the weft thread

A needle loom with automatic change of the weft thread, comprising:

• a bearing structure (2);
• at least one textile-product (P) forming head (3) installed on the bearing structure (2), said head (3) having a bearing plate (4) for formation of the textile product (P);
• at least two heddle frames (6) for intercepting a plurality of warp threads (O) fed to the bearing plate (4);
• at least one sickle (9) to bring at least two weft threads (T) transversely between said warp threads (O);
• at least two movable guides (11) each of which is adapted to guide one of the weft threads (T) supplied to the sickle (9);
• actuator means (13) to move said at least two movable guides (11) along a predetermined direction (D) and change the weft threads (T) carried by the sickle (9);
• at least one needle (18) to temporarily retain at least one of said at least two weft threads (T) carried by the sickle (9);
• and
• a reed (20) movable between a release position and a compacting position, to compact the weft threads (T) against the already formed textile product (P);
• wherein the actuator means (13) comprises at least two electric motors (21), each of which is connected to a respective guide (11), and motion-transmitting means (24) interposed between each electric motor (21) and the respective movable guide (11);
• wherein each motor (21) pulls or push the respective guide (11) downwards and pull or push the respective guide (11) upwards, to actively move the respective guide (11) in a first way (X) along the predetermined direction (D), upon command of the respective motor (21) and actively move the respective guide (11) in a second way (Y) along said predetermined direction (D), upon command of said motor (21), without adopting passive return elements.
