<p>The fmishing station (1) of variable structure comprises two plates (36, 36'), joined integrally to each other and able to slide along two vertical shoulders (44) which support a plurality of forming rollers (29) mounted on shoes able to slide in radial guides (30) formed in the plates (36, 36'). The shoes that support the forming rollers (29) are moved by levers (32) hinged to the plates (36, 36') and connected to each other by connecting rods (34), two of which are hinged to levers (35) hinged to the plates (36, 36') and secured to the ground. A further forming roller (40), situated in the lower part of the plates (36, 36'), is preferably secured to the ground. In the inner part of the two forming rollers (29) situated in the upper part of the finishing station (1) a disc blade (46) is formed to control the position of the edges of the bent strip of sheet metal during the finishing operation.</p> |
