Abstract
An expansion joint is provided for a rotary ironer or the like employing concentric cylinders defining a passageway through which thermal liquid passes. The joint comprises a toroidal segment which is secured in fluid-tight engagement to adjacent ends of the concentric cylinders. The provided joint enables one cylinder to be heated in advance of the other and expand while retaining a fluid-tight connection between the cylinder ends.
