Claims

[Scope of Claim for Utility Model Registration] (1) In a roll forming machine in which a roll shaft installed horizontally on each roll stand is rotationally driven via a gear mechanism by a line shaft in the forming direction, a predetermined roll stand on the downstream side The diameter of the roll shaft is larger than the diameter of the roll shaft of the roll stand on the previous stage, and the roll reference diameter of the roll stand on the rear stage is larger than the roll reference diameter of the roll stand on the front stage, The line shaft is divided into a front-stage line shaft and a rear-stage line shaft, and both line shafts are connected via an eccentric shaft joint that transmits rotation by shifting the shaft center by a predetermined eccentric distance in the height direction. . A roll forming machine, comprising: a drive device for driving either the front-stage line shaft or the rear-stage line shaft. (2) In a roll forming machine in which a roll shaft installed horizontally on each roll stand is rotationally driven via a gear mechanism by a line shaft in the forming direction, the diameter of the roll shaft of a predetermined roll stand on the subsequent stage is determined by The diameter is larger than the roll shaft diameter of the front roll stand, and the roll reference diameter of the rear roll stand is larger than the roll reference diameter of the front roll stand, and the roll stand corresponds to the rear roll stand. A roll forming machine characterized in that the output shaft of the gear mechanism and the roll shaft are connected via an eccentric shaft joint that transmits rotation by shifting the shaft center by a predetermined eccentric distance in the height direction.
