(54) Device for feeding a sheet for duplex copying and associated method of operation


(57) The device for feeding a sheet in equipment for generating images on both faces of said sheet, is of the type in which a stack of sheets (P1), (P2) and (P), having a first image on one face, is first stored in an intermediate tray, wherein it is piled step-like staggering each sheet by a determined distance, and comprises a flexible plate (50) having a first, substantially flat part and a second part, the continuation of the first part, inclined with respect to the first part by a determined angle, which is capable of assuming an idle position and a working position wherein it is raised by a loop formed by the bottom sheet (P1) of the stack, thus raising all the other sheets of the stack above the feeding rollers and permitting feeding of the bottom sheet (P1) only.
