The horizontal blade machine is used for cutting up cants from the canter line to reduce their sizes in order to process them more easily in other machines, such as multiple ripsaws.

To meet these needs, Primultini produces two types of beam saws: the DZA and the DZB, which, although similar in construction, differ in that the first cuts into halves heavy planks with only two machined faces, while the latter cuts squared logs with all four sides machined into several pieces.

The frame supporting the blade unit, feed bench and pressure roller unit is composed of large structural tubes to provide greater rigidity and stability.


Each of the two blade shafts is made from special high-strength steel. The structure supporting the shafts and motors is designed to reduce vibrations and noise and the bearings are fitted with locking nuts. Immediately behind the circular blades are the riving knives, which serve the purpose of keeping the cut open to ensure a good surface finish on the boards.


The machine is equipped with motorized toothed pressure/extractor rollers to ensure the stability of the plank during cutting and the removal of the sawn pieces.
