In this study, we research the mechanical properties of Capsule-Chuck which is a product to hold and turn a roll's core. Capsule-Chuck holds roll's core by swelling urethane loading Air pressure. We want to research the performance characteristic of Capsule-Chuck. When the roll's core contacts fixed parts of the capsule by increasing of load, dust is generated and the rolls of products are damaged. For that reason, we have to know the load limits of Capsule-Chuck and research maximum load of Capsule-Chuck by using the new experimental device and try to develop experimental formulas by using Hertz contact theory. So we assay cross-section shape of the capsule to obtain its curvatures for Hertz contact theory.
