The corrugated conveyor (17) containing the cores (4), the chain wheels (61, 62, 63, 64) and the at least two chains forming closed loops. Each chain lays at least three chain wheels (61, 62, 63, 64) and each buckle (4) is a joint with at least two chains. At least in the horizontal section of the corona conveyor (17), the roots (4) and / or the chains are movably movable along at least one guiding path. Advantageously, the roots (4) comprise a customs surface and, if at least one cross section of the rooster (4) has the shape of a trapezoid, the longer base of which is the cross section of the customs surface of the root (4).
