When using a rolling mill, the sheet should be supported in one hand, whilst the other turns the handle, thus drawing the sheet through the rollers. The sheet should be caught as it comes through, and its thickness checked using a vernier/calliper. Then, using a rolling mill machine again, reroll your sheet to achieve the required thickness.
