A system for controlling parameters of polymeric film in a continuous melt forming apparatus , the system comprising: an extruder configured to create a polymeric melt ; a die in communication with the extruder for receiving the polymeric melt from the extruder , the die having a gap (G) extending transversely along a discharge end thereof and plurality of regulators positioned transversely along the die proximate the gap (G) for selectively regulating the size of the gap (G); a cooling cylinder located downstream of the die in a machine direction (MD), the polymeric melt extending from the die to the cooling cylinder ; at least one haze generator located proximate the gap (G) and upstream of the cooling cylinder , the at least one haze generator being configured to create at least one haze lane (14, 14', 14") in the polymeric melt at a respective origin point (P1, P2, P3) proximate the gap (G) during production of the polymeric film ; a haze sensor system being located downstream from the gap (G) in a measuring location of the haze lane (14. 14', 14") where the polymeric melt has been quenched to form the polymeric film , the haze sensor system being configured to locate a transverse point (LP1, LP2, LP3) for the respective haze lane (14. 14', 14") in the polymeric film at the measuring location ; and the haze sensor system being in communication with the plurality of regulators to adjust the size of the gap (G) based on a correlation of haze lane (14, 14', 14") position at the respective origin point (P1, P2, P3) and the respective transverse point (LP1, LP2, LP3) at the measuring location , characterized in that the at least one haze generator is moveably positionable transversely along the die . an extruder configured to create a polymeric melt ; a die in communication with the extruder for receiving the polymeric melt from the extruder , the die having a gap (G) extending transversely along a discharge end thereof and plurality of regulators positioned transversely along the die proximate the gap (G) for selectively regulating the size of the gap (G); a cooling cylinder located downstream of the die in a machine direction (MD), the polymeric melt extending from the die to the cooling cylinder ; at least one haze generator located proximate the gap (G) and upstream of the cooling cylinder , the at least one haze generator being configured to create at least one haze lane (14, 14', 14") in the polymeric melt at a respective origin point (P1, P2, P3) proximate the gap (G) during production of the polymeric film ; a haze sensor system being located downstream from the gap (G) in a measuring location of the haze lane (14. 14', 14") where the polymeric melt has been quenched to form the polymeric film , the haze sensor system being configured to locate a transverse point (LP1, LP2, LP3) for the respective haze lane (14. 14', 14") in the polymeric film at the measuring location ; and the haze sensor system being in communication with the plurality of regulators to adjust the size of the gap (G) based on a correlation of haze lane (14, 14', 14") position at the respective origin point (P1, P2, P3) and the respective transverse point (LP1, LP2, LP3) at the measuring location , characterized in that the at least one haze generator is moveably positionable transversely along the die . <EOS>
