A guide is adapted to be positioned for encirclement by a helical formation of rod rings free falling from the delivery end of a conveyor. The guide comprises a vertically projecting mandrel terminating at its upper end in a nose cone. The nose cone has a horizontal profile defined in part by at least one element having an outer edge separated by a variable radial distance from a central axis of the mandrel.

An aluminum plate coiling device capable of coiling an extruded and rolled aluminum plate without generating distortion or deformation of the aluminum plate is disclosed. The aluminum plate coiling device has a simple structure, thereby being capable of achieving a reduction in installation space and a reduction in installation cost.

The invention relates to a method for preventing shape changes in metal coils, in particular for preventing a collapsing of newly wound hot coils. In the method, a metal coil, in particular a newly wound hot coil, is rotated about its longitudinal axis intermittently in a first rotational direction and then rotated back in a second opposing rotational direction, or further rotated in the first rotational direction.
