Shape Defects Machine Concepts

Virtually all shape defects in flat rolled strip are caused by non uniform dimensions and most can be corrected. When flat metal strip is really flat all the dimensions of the strip are equal. This means that thickness is uniform, the length of the strip is uniform from edge to edge and in line with the strip. If any of these dimensions
