ABSTRACT:
The roll forming machine includes a base, a motor drive, a power transmission connected to the motor drive, a rafted roll form assembly including a raft plate and a plurality of vertically aligned power rotated longitudinally spaced pairs of complemental rolls, arranged in a set to successively and operatively receive and feed there between elongated strips of stock, and a gear train including a plurality of gears and a drive gear interconnecting the set of rolls. The transmission includes a drive shaft connected to a gear reduction box having a power rotated sleeve aligned with the drive gear of the gear train. In order to change the rafted roll form assembly including the raft plate and the set of complemental rolls carried by the raft plate to another roll form assembly for making another metal part, a quick disconnect structure is provided which includes a drive clutch on the drive gear of the gear train of the raft assembly. The structure includes a normally retracted reciprocal jaw clutch which is slidably keyed to the sleeve and rotatable therewith, and a motor includes a reciprocal member connected to the drive clutch for advancing it into drive engagement with the drive gear.
