Abstract

A method for coiling thin metal strip, especially hot-rolled or cold-rolled thin steel strip, on a coiler mandrel which is adjusted in diameter. At the beginning, the inner windings of the coil are coiled on the adjusted coiler mandrel diameter and, after the final winding of the coil, the coiler mandrel is pulled out or the coil is taken off. At least the first inner winding is joined over a large area with the second inner winding by introducing adhesives, fillers, pieces of metal, bonding agents, or the like into an angular space between the inner windings.
