Example of a customized system for the production of three-layer elements
Laying element materials
Top layer: larch, beech, birch, the species of wood traditionally used for parquet. Intermediate layer: resin layer.
Third layer (intermediate layer): species of wood of secondary quality
Laying element dimensions
Min. width: 140 mm; Max. width: 205 mm – Min. length: 1,020 mm; Max. length: 2,400 mm
Min. thickness: 12 mm; Max. thickness: 22 mm – Type of profile: traditional “tongue and groove"
System output
Max. 25 pieces/min. 1.830 mm for length - Max. 3200 sq m/shift – Max. 700,000 sq m/year per work shift Incoming barrelful dimensions
Max. width: 205 mm – Max. length: 2,400 mm – Min. thickness 12, Max. thickness 22 mm
Machines and execution processes
1 line loading system with extraction of the barrelfuls. 1 lower sizing machine. 1 upper sizing machine. 1 upper sanding machine. 1 longitudinal squaring machine. 1 transversal squaring machine. 1 upper sanding machine in the plank repair process.
1 collet-type unloading system. Automation and alignment of the machines. PLC line management.
System Layout
1. Loading of single barrelful
2. Sizing and sanding
3. Selection and overturning of the planks
4. Profiling, brushes and hopper
5. Straightening and visual quality check
6. Deviation of the planks to be repaired
7. Sanding and formation of the plank pack
8. Formation and stacking of the plank pack
9. Formation of the stack
10. Offloading of the stack

TECHNOLOGY
permits elevated output and permit the use of minimum weight formats with notewor- thy savings of material.
Paint and varnish producers have by now specialized and diversified their products by type of finish and by cycle. This means that acrylic- and UV polyester-base primers and finish coats formulated for extremely short cycles with high abrasion resistance and ex- cellent adherence and elasticity can now be found in the market.
Conclusions
The productive process future, which will most likely be based on automatic fabrication with CAM (Computer Aided Manufacturing) and CIM (Computer Integrated Manufac- turing) management keeps getting closer and closer. It is also an accepted fact that robot- izing certain processing phases, innovative work centers and logistic systems combined with more and more flexible and personal- ized productive cycles and processes will provide considerable advantages in both pro-
ductive (shorter and shorter fabrication times with higher and higher output and ef- ficiency) and economic (lower overheads and rationalized resources) terms, in addition to greater abundance of the offer. In my opin- ion, all this should not lead to standardiza- tion but rather the contrary: the objective and real possibility of access to more innovative single devices, machines and production lines should stimulate entrepreneurs to im- prove the quality of their products.
Even if they are elementary in form, the above is always the result of a specific project that through a precise and analytical technical-pro- ductive procedure that permits the discovery of personalized solutions by involving the company first and foremost of all. These are the forms of personalization that character- ize multilayer parquet and wood flooring el- ements thanks to the quality of the tools, equipment, machines, systems, and lines that permit the fabrication of millions and mil- lions of laths, boards, planks, and maxi- planks for every taste, every day.
