ABSTRACT:
Laminate layers, such as a label and its liner, are separated by bending lengthwise-adjacent portions of the laminate end in opposite directions 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. The bending is carried out by forcing the laminate end into a narrow cavity with a finger-like member and using the combination of a compressible member and a support to frictionally restrain the laminate longitudinally. In preferred embodiments layer separation means are combined with cutting members for severing a length of laminate from a larger piece thereof.
