ABSTRACT:
A device (10) for extracting and feeding sheets from two trays, comprising a first tray (20) to contain a first ream (21a) of sheets (21), a second tray (30) to contain a second ream (31a) of sheets (31), and a feeding member (50, 53, 53a, 53b) for extracting and feeding one sheet (21, 31) at a time from said first ream (21a) or from said second ream (31a), wherein the two trays (20, 30) are positioned one on top of the other on the same side of the feeding member (50), and the second tray (30), in an intermediate position between the first tray (20) and the feeding member (50), comprises a fixed wall (32, 32a, 32b), to support the second ream (31a), which is configured in order to define an opening or cooperation zone (41) between the first tray (20) and the feeding member (50), so that, when the second ream is not present in the second tray (30) the feeding member (50, 53, 53a) and the first ream (21a) are intended to cooperate in contact with each other, through said cooperation zone (41) in order to extract and feed a sheet (21) from the first ream (21a) contained in the first tray (20). The device of the invention has a compact, inexpensive structure and is realized with a limited number of parts, and guarantees an accurate and silent functioning, reliable in time.
