<p>The invention relates to equipment (3) for drawing a film made of synthetic material, which includes longitudinal drawing means (11) and transverse drawing means (15) comprising a drawing enclosure (16), an air outlet opening (17) leading into the enclosure and an air inlet opening (18) leading into the enclosure. The transverse drawing means further comprise an air recirculation circuit (19) connecting the air inlet and outlet openings (18, 17) and designed to redirect the air from the air outlet opening towards the air inlet opening. The air recirculation circuit (19) comprises a cyclone separation device (21) including a body (22) defining a separation chamber (23), an inlet port (24) leading into the separation chamber and connected to the air outlet opening (17) of the enclosure so as to enable an air/additives mixture to be introduced into the separation chamber, an air outlet port (25) leading into the separation chamber and connected to the air inlet opening (18) of the enclosure, and an additive outlet port (26) leading into the separation chamber.</p> |
