A sandwich buttering machine comprises a hopper 11 containing butter which is to be deposited via an applicator roller 15 on slices of bread 18a, 18b being carried by a conveyor belt 19. A lifting device 20 brings each slice into contact with the applicator roller. The lifting device 20 is actuated in response to a signal from sensor 25 that senses the arrival of a slice of bread 18a.
