PROCESS FOR THE LAMINATION OF FINISHED PROFILES OF CRUDE PROFILES THROUGH LAMINATORS, OPERATING IN REVERSIBLE REGIME A process for laminating finished profiles of a raw profile through sets of laminators operating in reversible regime. One of these units is a compact laminating group that consists of two universal laminators with an intermediate settlement laminator arranged in an intermediate position. Another unit is a pre-lamination group that consists of vertical and horizontal laminators or universal laminators. For laminating sheet pile wall profiles, (U) walls, angular profiles or similar profiles, by equipping the laminators of the pre-lamination group and / or the compact lamination group with several selective gauges, selectively insertable in the line lamination, that is, by displacing the laminators, transversely towards the lamination line, 1 a rough profile of dimensions similar to the final product will be pre-molded in the laminators of the pre-lamination groups, in a row of format change steps or reduction of shape with or without the use of selective gauges and then in the compact lamination group, in several steps of modification and reduction of shape, in the entry laminator, in the intermediate settlement laminator, with or without the use of selective gauges, that is to say of adjacent gauges, continue to be molded and subsequently in the exit laminator or in the intermediate settlement laminator it becomes molds to compose the final profile.
