-   Cubes cutting machines with a rotating cutting tool, a multi-segment blade and a feed conveyor (see Figures 3 and 5)
-   Cubes cutting machines with a rotating cutting tool and centrifugal force loading (see Figure 6)
1.3   Machine construction
Cubes cutting machines are constructed of a machine frame, a feed intake chamber/magazine, a forward feed plunger or nip roller, a lattice or a rotating cutting tool, a sickle or multi-segment blade, an associated drive and electrical, hydraulic and pneumatic components, depending on machine type.
Cubes cutting machines in the scope of this document may be equipped with:
-   a lid over the feed intake chamber/magazine;
-   a transfer car for the sickle blade/multi-segment blade, cutting blade and lattice;
-   a loading device;
-   a feed conveyor.
