ABSTRACT:
A method and apparatus is disclosed for decelerating and temporarily accumulating a hot rolled product moving longitudinally along a receiving axis at a first velocity V1. The product is directed through a curved guide having an entry end aligned with the receiving axis to receive the product, and an exit end spaced radially from the receiving axis and oriented to deliver the product in an exit direction transverse to the receiving axis. The curved guide is rotated about the receiving axis in a direction opposite to the exit direction of the product and at a speed at which the guide exit end has a velocity V2, thereby decelerating the product being delivered from the guide exit end to a reduced velocity V3equal to V1−V2. The curvature of the guide and the orientation of its exit end is such as to form the delivered product into a helix deposited and temporarily accumulated on a cylindrical drum. The drum is rotated in a direction opposite to the direction of rotation of the curved guide to thereby unwind the product from the drum.
