ABSTRACT:
Laminate layers, such as a label and its liner, are separated by directing both layers at an end of the laminate around a sharp bend to cause shearing and lengthwise offset between the layers, and then releasing the end, the overall orientation being such that, upon release of the end, a differential in the forces that tend to straighten the layers drives apart the shear-weakened adhesive bond.
