Pexto forming machines included in this section offer a broad variety of shapes and capabilities in forming sheet metal for a combination of uses: beading, crimping, setting down, double seaming, turning, burring, wiring, elbow edging, flanging, and flattening. All are precise in the job they do and are readily adaptable to job requirements. The roll chart is indicative of their flexibility. Most are portable and may be set up at the job with a clamp-on base. These machines include Ogee bead and crimping rolls to provide one pass combined crimping and beading. They are adjustable for deep or shallow beading and for “fade-away” crimping. By replacing the beading rolls with spacing collars (furnished), the machines can be used for crimping only. 3/8″ and 1/2″ Single Bead Rolls are available for the No. 0585 machine.
