A machine for the continuous binding of books and booklets, includes clamps
mounted on a chain for the transport of groups of sheets to be bound along
various stations. Each clamp is provided with a manual opening mechanism.
A sheet levelling device includes two parallel horizontal plates joined by
connecting elements, the lower of which is permanently fixed to the
