A method of slicing a loaf of bread by means of a bread slicer, said slicer comprising: - a loading compartment having a support surface for placing a loaf of bread to be sliced, the loading compartment being connected to a receiving compartment with a bottom, - a bagging pallet provided in the receiving compartment, this pallet being movable between a receiving position, in which the pallet extends along the plane of the bottom of the receiving compartment, covering a recess provided in this bottom, and a bagging position, in which at least one end of the pallet is raised relative to the plane of said base so that the recess is accessible from the receiving compartment, according to the method, the loaf of bread to be cut is placed in the loading compartment and, in a cutting step of the method, the loaf of bread is advanced in a direction of movement towards the receiving compartment and successive slices are cut from the loaf of bread during its movement towards the receiving compartment by the movement of a cutting blade along a cutting plane extending between said compartments (1, 4) and substantially transversely with respect to said direction of movement, the slices cut from the loaf of bread are advanced until they are on said bagging pallet which is held in the receiving position and, after the loaf of bread has been completely cut, the bagging pallet is moved towards the bagging position while freeing said recess in the bottom of the receiving compartment, this method is characterised in that the cutting step is preceded by a cleaning step in which a pusher is moved from the loading compartment towards the receiving compartment, when the bagging pallet is in the bagging position, to push, by the movement of the pusher, remaining parts of a previously cut loaf of bread towards said recess until they fall into this recess, the movement of the pusher then being reversed and the bagging pallet is returned to the receiving position. - a loading compartment having a support surface for placing a loaf of bread to be sliced, the loading compartment being connected to a receiving compartment with a bottom, - a bagging pallet provided in the receiving compartment, this pallet being movable between a receiving position, in which the pallet extends along the plane of the bottom of the receiving compartment, covering a recess provided in this bottom, and a bagging position, in which at least one end of the pallet is raised relative to the plane of said base so that the recess is accessible from the receiving compartment, according to the method, the loaf of bread to be cut is placed in the loading compartment and, in a cutting step of the method, the loaf of bread is advanced in a direction of movement towards the receiving compartment and successive slices are cut from the loaf of bread during its movement towards the receiving compartment by the movement of a cutting blade along a cutting plane extending between said compartments (1, 4) and substantially transversely with respect to said direction of movement, the slices cut from the loaf of bread are advanced until they are on said bagging pallet which is held in the receiving position and, after the loaf of bread has been completely cut, the bagging pallet is moved towards the bagging position while freeing said recess in the bottom of the receiving compartment,
