with dimensions 1,500 x 6,000 mm.
The line also includes a weighing system for nished packs, pro- viding all the essential job data required by the client, including the nal identi cation label with bar code.
One of the most important inno- vations in this system is without a doubt the rotary shear cutter, which in addition to being a sophisticated and highly accu- rate construction, also features an exclusive “oblique angle” cor- rection system, which adjusts the entire shear cutter in the right direction and to just the right extent to correct the defect.
Thanks to this function, the line allows the reduction and elimi- nation, within certain limits, of strips with “chamber” on cus- tomised sheets, representing an important step forward towards improved quality, but also towards overall consistency.
Another important innovation is represented by the levelling roller cleaning device. The consequences of dirt, dust or foreign bodies on rollers are well-known to all, par- ticularly in the case of polished laminates intended for particu- lar applications. In traditional systems, cleaning was performed more or less manually, entrusted to the diligence of operators in charge of the line, and therefore devoid of any real guarantees. In the new Faspar line on the other hand, cleaning is entrusted to a safe system incorporated into the levelling machine itself, which following a request by the oper- ator from the control desk, dis- tributes programmed quantities of a special detergent onto the levelling rollers, which are subse-
quently cleaned of any impurities and therefore able to treat the metal in the best way possible.
A third aspect worth mentioning in this line is the presence of a “quality selection box”, preced- ing the two stacking boxes we’ve already seen. Space has been left in the line to allow the material to be visually inspected by a spe- cialised and expert operator. If a defect is found, the operator sends a signal, which is automati- cally managed by the line PC, and which after taking into account all the parameters, directs the defective sheet into the dedicated box by way of the output con- veyor belt.
Thanks to its careful and accurate construction, and by way of these innovations, the new Faspar line has become the strong point of the new service centre production.
This case, a commendable example of cooperation between system manufacturers and users, with a bene cial and reciprocal exchange of knowledge and experience, demonstrates the high techni- cal level that can be achieved by Italian producers of machinery, and by companies that operate in the processing sector for strips made from noble materials, intended for high-quality uses.
