Slitting Lines

Metal slitting machines can shear and cut sheet metal into specific dimensions and lengths. VX-LLC carries an impressive inventory of slitting lines available for purchase.

What Is a Slitting Line?

A steel master coil is cut longitudinally along a slitting line to predetermined thinner widths. These smaller coils, or “mults,” are then delivered to downstream operations that will use the material in their finished goods, including metal stampers, tube manufacturers, or roll-forming processes. Slitting lines can often handle coils that are 8” to 96” wide, 5 to 60 tons in capacity, and .006” to 1.00” thick. Speeds of 100 to 2,000 feet per minute can be achieved, depending on the material thickness and yield strength.

How Slitting Lines Work

Metal coil is loaded onto the uncoiler, which then feeds the material to edge guides before the flattener and leveler (if applicable). Then the slitter, which consists of two parallel arbors mounted with rotary cutting knives, partially penetrates the coil stock causing a crack or fracture on both sides of the stock, separating the mults from one another.

The coil’s outer edges are trimmed after being slit, where a scrap winder collects this edge trim. If the material to be slit is very thin, a looping pit can be employed to accommodate the variable thickness of the mults.

The recoiler then takes up the slit mults. There, the finished slit mults are banded on the outside and pushed off the recoiler mandrel onto an awaiting coil car or turnstile.
