Basic explanation - shear two step process:

 Step 1: Sheet metal stock is fed directly into the shear until contact is made with the adjustable back gage. The  shear is then activated, material hold downs clamp the sheet metal in place while the shear blade comes down and cuts the sheet metal into desired width strips.
 
 Step 2: Sheet metal strips from step one are collected and then held against the squaring arm to keep the strip edges square with the shear blade. One at a time the strips are fed into the shear until contact is made with the adjustable back gage, each time the back gage is contacted the shear is activated and the strips are cut a second time into rectangular shaped blanks of the desired size.
