The invention relates to a machine (1) for giving three dimensions to (forming into volumes) trays (2) each comprising a base, particularly a flat base, as well as a peripheral rim, these trays being produced by successive folding of flaps of a blank (9) of pre-cut-out material, which machine consists of at least: - one frame (1a), - a magazine (24) for storing a plurality of blanks (9) organised in at least one stack (25), - a station (30) for giving three dimensions to (forming into volume) at least one blank, particularly employing devices (31, 32) for raising the end and lateral flaps above a plane defined by the bottom of the tray, - a device (33) for removing a blank from the magazine and then introducing this blank into the station for giving three dimensions (forming into volume), which device comprises at least one gripping member (34), - a device (35) for ejecting each tray which has been given three dimensions (formed into volume) towards a discharge device (36), the said ejection device also comprising at least one gripping member (37). <IMAGE> |
