Abstract:
1. A method of decelerating and temporarily accumulating a hot rolled product moving longitudinally along a receiving axis at a first velocity V 1 , said method comprising: directing said product through a curved delivery guide having an entry end aligned with said axis to receive said product, and an exit end spaced radially from said axis and orientated to deliver said product in an exit direction and at an exit angle ∞ with respect to a reference plane perpendicular to said axis; continuously rotating said delivery guide about axis in a direction opposite to said exit direction and at a rotational speed at which said exit end has a velocity V receiving and temporarily accumulating said helix on a cylindrical drum aligned on said axis; rotating said drum about said axis in a direction opposite to the direction of rotation of said delivery guide to thereby unwind the product accumulating temporarily on said drum; arranging a receiving guide at an initial position to receive a front end of the product unwinding from said drum; upon receipt of said product front end by said receiving guide, rapidly moving said receiving guide from said initial position and along a linear path parallel to said axis through an initial distance X=L·sin θ where: the movement of said receiving guide through said initial distance being accomplished in the time that elapses between 1 and 3 revolutions of said delivery guide.
