Abstract
An arrangement for winding material onto a coiler drum along a passline of a hot reversing mill comprising an apparatus having two pivotal arms mounted on a common shaft and movable in a different arcuate path toward and away from the coiler drum. Rollers at the end of the arms tightly enwrap the material around the drum when the arms are positioned against the drum as the material is being underwound onto the drum. The roller of one of the arms may act as a deflector roller when positioned away from the drum as the material is being overwound onto the drum. The other arm consists of two wrapper rollers on a pivotal mounting for their proper orientation around the drum and for flat passes of the material through the mill. This other arm is positioned away from the drum below the passline to allow a retractable table roll assembly consisting of a plurality of table rolls to be positioned in the passline for supporting the material.
