ABSTRACT:
In a currency alarm pack, greater flexibility is achieved by multiple circuit boards and an alarm device, connected together by a thin, flexible substrate having printed conductors. The components are movable relative to one another for realistic flexure of the stack. At least two of the components are slidable relative to the stack along its direction of elongation as the stack is flexed. Portions of the substrate have tabs which extend laterally between opposed peripheral portions of adjacent intermediate sheets of the currency pack so that the alarm components are supported and can slide longitudinally as the stack is flexed. Adjacent components are connected by narrow portions of the substrate, which permit torsion of the stack. These narrow portions extend transverse to the surfaces of the currency sheets to allow the alarm components a high degree of relative movement. Compressible foam pads conceal the presence of the alarm components. The intermediate sheets of the pack are stitched together loosely by threads to permit shear motion of the pack while maintaining its integrity. The threads have loops extending laterally across the outermost intermediate sheets to hold flexible covers removably. In another version, each opening of the central cavity is covered by two flexible flaps pivoted near the ends of the alarm packs.
