ABSTRACT:
A six stage rolling machine for forming endless metal belts from tubular workpieces comprises, a first roll disposed within the workpiece, a second roll disposed outside the workpiece and constitutes, in cooperation with the first roll, a pair of work rolls for effecting one position rolling of the tube into a belt. The first roll is provided with a pair of back-up drive rolls capable of being contacted with the first roll under pressure to play a role as backing up and driving rolls, similarly, the second roll is also provided with a pair of rolls capable of being contacted with the second roll under pressure to play a roll as backing up and driving rolls, that is, the rolling machine comprises a pair of work rolls and four back-up rolls, that is, six rolls in total. The front side of the machine body at one axial end of the first roll and the side from which the finished belt is discharged are open and contiguous and are exposed to the outside the rolling machine, moreover, the portions adjacent these areas are provided with respective subsidiary means, namely, a feeder in which a supply of workpieces waiting rolling are stored and a delivery member for sending out the product belts are disposed, in addition, there is also disposed, at the front of the machine, a transfer means which transfers the workpieces from the feeder to the first roll and finished belts from the first roll to the delivery member.
