The invention discloses a system (I) for powder coating elements to be coated of considerable length, characterised in that it comprises, within an overall occupied floor space (800), a safety area (50) dedicated to the work activities of personnel, exhibiting a zone dedicated to the stage of loading (100) and a zone dedicated to the stage of unloading (600) the finished elements (1) from the overhead conveyor line (2), said safety area (50) marking the perimeter of a single, central block (101) exhibiting the activities of the production process and the specific units predisposed thereto and identified as a unit (200) dedicated to the pre-treatment of the elements to be coated, a unit (300) dedicated to the drying of the elements to be coated and a unit (500) for the polymerisation of coating powders deposited on the elements to be coated, there being further provided a unit (400) dedicated to coating and an overhead conveyor line (2) for the elements to be coated (1) that extends with a winding path. The invention further discloses a procedure for coating elements to be coated of considerable length (1), characterised in that it provides a coating booth (401) that has a triangular plan schematically identified by a first, a second and a third vertex (A, B and C), and a conveyor line (2) for the elements (1) that enters a side (BC) and extends along a path that brings said elements to be coated (1) toward said first vertex (A) and then returns and has said elements to be coated (1) exit from said side (BC) in a substantially symmetrical position with respect to said first vertex (A), said path being configured so that the elements to be coated (1), in transit in the booth, encounter direct spraying by sets of electrostatic spray guns (10 and 11), and coating powder, which, given that it has not directly deposited on said elements to be coated (1), travels toward a vertical suction inlet (12) located at said first vertex (A), and encounters the array of profiles in transit prior to being suctioned. |
