Abstract
Flat metal strip of indeterminate length is apertured in a punch press having a flying die set to define a lengthwise succession of identical workpiece blanks connected by strap-like portions of the strip adjacent to its longitudinal edges. That press, each time it operates, makes two apertures that define respective end edges of a blank. The strip is pulled lengthwise through that press by roller forming apparatus which imparts a predetermined transverse profile to it and propels it through a flying shear press whereby each blank is severed from the rest of the strip. On a conveyor having two stretches bridged by the severed blank and moving faster than the strip the severed blank is carried to a folding press. There a ram rises from between the conveyor stretches, lifting the blank off of the conveyor and clamping it against a folding die. The ram raises the blank and the die until the die is stopped, whereupon the ram rises somewhat more to fold the blank, then descends to bring the workpiece down onto other conveyor stretches that carry it away.
