<p>A sheet feeding method and apparatus particularly suited to handling plastic sheets having a tendency to adhere to each other under electrostatic action, in which the uppermost sheet (M) of a stack is fed by first lifting the rear edge of the sheet into a generally arcuate configuration and translating a lifting member (34) forwardly under the lifted rear edge to progressively separate the uppermost sheet from the rest of the stack. The lifting members preferably in the form of an idler roller which translates to a position in cooperation with a drive roller (44, 46) so that the sheet becomes sandwiched between the two rollers for final feeding from the stack. The mechanism features a pick assembly (124) particularly suited for engaging and lifting the rear edge of each sheet into a predictable arcuate configuration.</p> |
