However, in panel benders,the bending work is performed by the blades, while the blank holder holds the sheet still during bending. The blades are thus able to perform different types of folds, upwards or downwards,beginning with the outermost bends of one side, before then automatically performing the bend sequence towards the innermost bend. All of these movements are controlled by electric servo drives that guarantee maximum positioning accuracy in the bending trajectory, thus ensuring an optimal result.
