    Abstract: A method of underwinding strip on a drum along the passline of a hot reversing mill comprises positioning the drum in a receiving mode, passing the strip through the mill at a given thread speed, detecting the presence of the strip at a given position in relation to the drum, activating the drum in an underwinding direction at a given time delay representative of a distance in which the strip is through the drum slot and internal of the drum, and speed matching the drum and the strip in an initial surface winding mode and a subsequent center driven tension mode. The apparatus includes a pair of drums, each positioned on an opposite side of the hot reversing mill, a pair of gates, each positioned along the table rolls to deflect the strip into the drum slots, a tilt table roll assembly on each side of the mill adapted to pivot into engagement with the drum downstream of the slot to retain the strip against a portion of the drum, detection means positioned between the drum and the mill to detect the presence of the strip, activation means for causing each drum to rotate in an underwinding direction when the strip enters the slot, and to speed match each drum to the strip, and a converting means for converting each drum from a surface winding mode to a center driven tension mode after a given number of wraps.
