An apparatus and method are provided for separating two objects attached to each other in a sandwich structure, such as a stamp and a substrate pressed together in an imprint process. The apparatus includes a support structure, carrying first fastening means having a base surface and first gripping means for supporting and holding a first object, second fastening means, positioned opposite to the first fastening means, having second gripping means for holding a second object, and a pulling force mechanism to provide a pulling force at an angle to the normal direction of the base surface for displacing the two fastening means away from each other. Preferably, the second object is gripped at a periphery portion, and the pulling force is angled inwardly from said periphery portion.
