Aaa read this before brow - Comparison of a Folder & a Press Brake, ID#FOLDERS VS PRESS BRA
Folding: Bending sequence
During the folding sequence the blank rests on the sheet support table. A gauging system positions the part to the bend line. The upper and lower beam clamp the blank. During the bending cycle the folding beam moves up around a pivot point. On up-down acting machines, the folding beam moves upwards or downwards, depending on the bending direction.
The part rests on the table (no fatigue, short cycle times)
The gauging system positions the part to the bend line (operator training finished in no-time)
Upright posture, easy operation (no health problems)
Usually one operator is sufficient even for large, cumbersome and heavy parts (low labor/parts costs)
