An apron forming apparatus and method for bending and joining the ends of a pair of apron half segments includes a series of four apron support surfaces lying in a common plane. A clamping arrangement is mounted on each of the apron support surfaces for selectively clamping an apron half segment. A bending arrangement is secured to each of the apron support surfaces for selectively bending an apron half segment. Each of the apron half segments is disposed between a clamping arrangement and a bending arrangement on a pair of apron support surfaces such that the apron half segments lie substantially parallel to each other. Each of the bending arrangements is movable into engagement with an apron half segment to bend the apron half segment such that the ends of one bent apron half segment are placed in overlapping relationship with the ends of the other bent apron half segment. A fastening arrangement is provided for joining the overlapped ends of the bent apron half segments while the apron half segments are positioned on the apron support surfaces. A mechanism is supplied for moving the clamping arrangement and bending arrangement on certain of the apron support surfaces along a first axis substantially parallel to the longitudinal axis of the framework and a second axis substantially perpendicular to the first axis so as to provide variously sized aprons.
