A machine for processing food products, which comprises a chamber (1) for conveying food products to be processed in which a pusher (2) is accommodated and is provided with a piston (3) that can be actuated for translational motion along a movement direction (3a) in order to push the food products toward an output end of the conveyance chamber (1); the conveyance chamber (1) has at least one variation in the dimension of its transverse cross-section with respect to the movement direction (3a); the pusher (2) has means for adjusting its transverse dimension with respect to the movement direction (3a) which are adapted to produce an automatic expansion or contraction of at least one lateral portion (4) of the piston (3), with respect to a longitudinal axis (3b) of the piston (3) which is substantially parallel to the aforementioned movement direction (3a). |
