ROLL FORMING MACHINE

摘要

A roll forming machine which includes an outboard housing (96) having dual t urrets (98-99), each turret carries a pair of rotatable arbors (113-114-115-116) which can carry forming rollers (117-118). The outb oard housing is slidable along guide rails between on-li ne and off-line positions. In the off-line position the turrets may be indexed to bring the second pair of arbors into a working alignm ent and thus reduce changeover and down time of the roll forming line.
