Abstract
A roll forming apparatus has an elevatable base that is moved up and down by an elevating mechanism. Carriages are movably mounted on the base on both sides of a forming pass line. Each carriage carries several side rolls that are disposed along the forming pass line. A pair of side roll position adjusting mechanisms are coupled to each carriage. The pair of side roll position adjusting mechanisms move a carriage back and forth to form the desired forming pass. An elevating mechanism is provided to move up and down the base so that the level and inclination of the forming pass line is set as desired.
