Rolling a hemmed wire edge into sheet metal.

How to stiffen sheet metal.

To form the operator marks the bend line on the sheet as a guide then lines it up with punch tip and performs a shallow bend. Sheet metal edge bending. The metal in the areas where holes and slots are punched gets stretched and become more tensile which gives more structural rigidity to the sheet metal. The most simplest way is to bend the boundary of the sheet slightly in an l shape wherever possible.

Folding over the edge of a piece of sheet metal will give the metal instant structural integrity. Perfectly for creating stiffening ribs in sheet metal parts as you ve.
