Abstract

THERE IS DISCLOSED A TAPERED MANDREL FOR A PLATE ROLLING APPARATUS IN WHICH THE MANDREL IS ADAPTED TO BE ROTATABLE BETWEEN SUPPORT FRAME ENDS SAID MANDREL INCLUDING A GRIPPER FOR HOLDING A PLATE THEREIN AND A PRESSURE ROLL DEVICE MOUNTED BENEATH THE MANDREL FOR MAINTAINING THE PLATE INCONTACT WITH THE MANDREL SO THAT UPON ROTATION OF THE MANDREL THE PLATE IS FORMED TO FOLLOW THE CURVATURE OF THE MANDREL TO FORM A TAPERED PIPE THE MANDREL INCLUDING A PLURALITY OF INTERCONNECTED TAPERED FRUSTO CONICAL SEGMENTS OF SHORT LENGTH RELATIVE TO THE OVERALL LENGTH OF THE MANDREL, EACH HAVING THE SAME TAPER ANGLE AND A LARGE DIAMETER END AND MATCHING SMALL DIAMETER END OF AN ADJOURNING SEGMENTS AND A SMALL DIAMETER END MATCHING THE LARGER DIAMETER END OF AN ADJOURNING SEGMENT, THUS JOINED SEGMENTS FORMING A TAPERED MANDREL OF A LEGTH TO SUIT SAID PLATE BENDING APPARATUS THE MANDREL HAVING A SMALL AND LARGE DIAMETER TO SUIT THE SIZE OF THE PIPE TO BE FORMED AND INCLUDING INTERCONNECTING PORTIONS AT THE ENDS OF EACH SEGMENT TO INTERENGAGE AND LOCK FOR ROTATION TOGETHER WITH THE GRIPPER PLATE ALIGNED THEREON TO FORM A TAPERED PIPE.(FIG. 1)
