  • A rundown on rolling machines - The FABRICATOR

    You often will see capacities for both prebending and rolling for any plate rolling machine. Prebending is performed on the plate roll at the leading and trailing edges of the sheet (see Figure 2)—and eventually the seam (see Figure 3).. A sheet cannot physically be bent right to the edge, and thus what remains is referred to as the unbent flat (see Figure 4).
