ABSTRACT:
A tuned card weight for biasing a stack of cards in a card feeder includes: (a) a base section having a pair of parallel edges, one of the edges having an extension forming an acute angle with one side of the section; (b) an elastomer cantilever coupled to the other side of the base section along the other of the edges, the cantilever having a handle at its free end; and (c) a metal rod extending through the handle for providing the resulting structure with a damped resonant frequency. The resonant frequency is provided such that it is greater than the rate at which the feeder operates.
