ABSTRACT:
A device for achieving a continuous forming of a metal rod or bar as it emerges from an extruder to impart desired repeating design characteristics therealong. The device includes a pair of co-acting motor driven forming rollers with complementary design portions formed in their engaging peripheral surfaces to engage the rod therebetween and to impart the forming roller design thereto. The forming rollers and variable speed drive motor are mounted on a carriage trolley movable on a track toward and away from the extruder in alignment with the extrusion emerging therefrom. The piston rod of a pneumatic piston and cylinder assembly is fixed to the carriage to impart a predetermined degree of pressure thereto in alignment with and in the same direction as the pressure forces of the metal rod extrusion. The drive motor is operated at a predetermined R.P.M. to create a condition whereby the driven forming rollers engagement with the extrusion substantially counterbalances the combined P.S.I. forces of the extrusion and piston rod permitting the trolley carriage to drift back-and-forth on the track in accordance with normal fluctuating P.S.I. forces of the extrusion without imparting deforming forces to the extrusion.
