The cassette can be mounted on a carriage of the machine by means of two projections projecting from the underneath of the bottom and which are capable of being pivotally mounted in two respective grooves and moving against two co-operating surfaces for oscillating movement about an axis parallel to the roller. A pin on one side of the container can be removably engaged into a seat of a connecting lever of the machine, which is connected to a displacement means.
