ROLL-FORMING MACHINE WITH ADJUSTABLE COMPRESSION

摘要

A roll-forming machine (10) is provided with a base structure (13), a plurality of first roll-forming stations (60a, 60i) that form a first component having a Z-shaped cross section (12a, 12j), and a plurality of second roll-forming stations that form a second component having a C-shaped cross section. At least one of the roll-forming stations has a pair of rotatable arbors (18, 26) adapted to support a plurality of forming rolls (14, 16, 22, 24) and a pair of support structures adapted to support a plurality of bearing assemblies (97, 99). The roll-forming station also includes a pair of adjustment mechanisms (150) that allow the position of some of the bearing assemblies to be adjusted and a pair of compression assemblies (360) that exert a force upon some of the bearing assemblies when the bearing assemblies are moved away from an initial position.
