A slitting and rewinding system having a tension stand assembly with at least one pressure pad is provided. The system includes a payoff, a slitter, a tension stand, and a coil rewinder. A roll of material, usually metal, is positioned on the payoff so that it is aligned with the slitter. The slitter is fed the material from the payoff and transforms the relatively wide stock into narrow strips. The strips are untensioned between the slitter and tension stand, and may form a loop. Tension is provided between the tension stand and the rewinder due to both the winding action of the rewinder and a pressure pad provided within the tension stand. The pad exerts uniform pressure on the strips as they pass through the stand, thereby helping to form the loop on one side and provide tensioned strips on the other. The system allows a wide metal coil to be processed without difficulty even if there are variations in thickness in the coil. The tension stand may additionally include an elevating mechanism for raising the pressure pad as the diameter of the rewound metal strips increases.
