Abstract:
1. Equipment for drawing a film in synthetic material, comprising: a first fluid circulation circuit in which a heat transfer fluid circulates, wherein the transverse drawing means further include an air recirculation circuit connecting the air inlet and outlet apertures and laid out so as to redirect the air from the air outlet aperture to the air inlet aperture, and wherein the air recirculation circuit includes a cyclone separation device comprising a body delimiting a separation chamber, an inlet orifice opening into the separation chamber and connected to the air outlet aperture of the enclosure so as to allow introduction of an air-additives mixture into the separation chamber, an air outlet orifice opening into the separation chamber and connected to the air inlet aperture of the enclosure, and an additive outlet orifice opening into the separation chamber, wherein the body of the cyclone separation device comprises a heat transfer fluid inlet and a heat transfer fluid outlet connected to the first fluid circulation circuit, and wherein the cyclone separation device comprises a cooling pipe positioned in the body of the cyclone separation device and including a first end connected to the heat transfer fluid inlet and a second end connected to the heat transfer fluid outlet.
