Hem Roll Set for Bead Rollers\u003c\/h2\u003e\n\u003cp\u003eHemming folds the edge of a sheet-metal panel back over onto itself. It does two things at once: stiffens a thin panel along its edge, and turns a raw, sharp cut into a clean, safe, finished edge. These rolls run in a standard bead roller and form the hem in three progressive passes rather than one hard bend, which keeps the metal from cracking or distorting.\u003c\/p\u003e\n\u003cp\u003eThe three steps build the hem in sequence:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep 1\u003c\/strong\u003e forms the metal to 90°.
