WNS Beading Machines are ideal for duct manufacturers. These machines have one pair of driving rolls and one pair of beading rolls. The sheet is placed on the entry table alongside the guide fences and then passed through the machine, producing stiffening beads. This enables a stronger duct to be formed and in some cases thinner material to be used.
These machines are available in four different sizes: 1275mm, 1550mm, 2000mm and 2500mm.
