SYSTEM FOR FOLDING AND ROLLING OUT A METAL PLATE FOR PRODUCING A STRAKE

摘要

The present invention relates to a system for banding and unrolling metal sheets (45) of various thicknesses for manufacturing strakes, the system (38) comprising a chassis (39) and a series of forming units (40, 41, 42). ), each forming unit (40, 41, 42) comprising: - two drive rolls 50 mounted with the ability to rotate in order to cause the metal sheet 45 to proceed in the direction of travel; - two forming rollers 52 , 53 ; - two pressing rolls 51 arranged to keep the metal sheet 45 pressed against the driving roll 50 and against the forming surface of the two forming rollers 52 , 53 ; and - mounted with the ability to slide relative to the chassis 39 along a vertical axis, the distance between the drive rolls 51 and the drive rolls 50 of the forming units 40 , 41 , 42 being the thickness of the metal sheet 45 a pressing roll support 54 , which is forced toward the drive roll 50 by a resilient urging member 55 to be dynamically applied to the includes
