Those customers who choose Pezzolato benefit from the advice of an expert partner, who assists them during all purchasing stages, installation and after-sales process.
Customised solutions
Should production requirements call for specific customization, the industrial equipment need standard components and custom-made elements.
Pezzolato, as highly experienced manufacturer, can design, manufacture and install automatic, perfectly integrated solutions.
Key features
S-shaped accumulation belt
In order to increase productivity exponentially, Pezzolato has always proposed processors capable of simultaneously cutting bundles of logs, whether they have homogeneous or different diameters and lengths.
These machines allow a huge amount of cut logs to be fed into the production process and, therefore, it is advisable to integrate a sufficiently large storage section to collect the material while waiting to proceed with screening and splitting. For this reason, Pezzolato has designed and developed over the years the so-called ‘S-belt’: an accumulation and transfer belt for cut logs consisting of a robust electro-welded structure with a closed chain, whose main function is to create a collection lung positioned before the splitting station.
Should it become necessary, the ‘S-belt’ also makes it possible for a single operator to manage the firewood processor independently, dealing with the cutting and splitting phases sequentially.
Double screw with variable passage for the separation of the logs
In order to increase productivity exponentially, Pezzolato has always proposed processors capable of simultaneously cutting bundles of logs, whether they have homogeneous or different diameters and lengths.
When the firewood processors are working on bundles of logs with different diameters, the cut logs need to be screened by size, then assessing whether or not their splitting is necessary.
The double screw with variable passage is a further step in the automation of the firewood production: the logs, once cut, fall into a machine that makes them move forwards to a double endless screw. The two screws work at an adjustable distance, which allows smaller logs (which do not require further splitting) to fall onto a belt that transports them directly to the storage point.
Belt for the loading of the cut timber
Once cut and split, firewood can be conveyed to different types of storage points: boxes, containers, heaps or directly to some means of transport on the road.
Pezzolato designed and developed over the years some belts for loading the cut firewood, ranging from the simplest to the most complex, all of which have in common the fact that they are practically not subject to wear and therefore guaranteed for life.
The discharge belt can be supplied in various configurations and options, depending on the actual production requirements. In fact, the customer can choose whether to integrate certain elements (e.g.: fifth wheel on the ground, motorization of the swivelling wheels, cleaning rollers, …), also defining unloading lengths and heights.
Tower distribution into containers
Among the various solutions chosen by Pezzolato for the unloading and distribution of the cut firewood inside adjacent boxes or containers, we now take into consideration the ‘tower’ system. This solution makes it possible, by means of a series of rubber belts, to bring the processed firewood to an elevated position over the boxes or containers where it will be then stored.
The Pezzolato ‘tower’ system allows the operator to act comfortably from the control panel of the equipment, choosing not only which container to unload into, but even changing the angle and depth of the unloading point. Thanks to a camera system, the operator visualizes the progressive filling of the containers and acts on the belt and its orientation by means of a fifth wheel and of the guides and rails.
The firewood is thus dropped in a precise area of the storage container, allowing an incredible optimisation of time and management costs, avoiding the need to intervene at a later stage in the distribution of the cut logs for the subsequent drying phase.

Screener for vibrating belt
In some plants, firewood is collected in large boxes until the right humidity level is achieved. At this point, by means of an automatic tilting system, the logs are transferred into a vibrating belt that feeds a dedicated screen for the final cleaning of the wood.
The cleaning screen brings the logs forwards. These logs roll and bounce, quickly losing their waste elements. This waste material can be collected by falling into a container or by reaching a storage point by means of a further conveyor belt.
