The main feature consists in having a fixed head, where cotton/sisal brushes for processing are mounted.
With an extremely robust, especially studied structure, absolute flatness of profile surface is ensured to guarantee always the same finish along the entire profile. Moreover, suction is excellent since it remains fixed in the same servicing spot, as the dust collector is linked directly to the head where the finishing cycle takes place, and where the paste-spraying guns are mounted. The machine is equipped with a main mobile pallet/base and 2 mobile platforms on which profiles are placed. The platforms shift initially on the main pallet/base and this occurs longitudinally, until the fixed head is reached, where the polishing cycle takes place. The structure is equipped with slides for the shifting wheels. Then, being the machine provided with a double mobile platform, loading and discharging operations from one platform take place while the other platform is being employed in the finish cycle.
The speed of the main pallet/base is controlled by an inverter and varies from 0 to 20 metres/ min., thus optimizing the production cycle. The processing cycle, handled by an Allen Bradley PLC, is extremely simple given the system’s top automation level. To ensure a wholly safe processing cycle, the pallets/bases are equipped with aerial clamps to lock profiles during processing. Besides assuring absolute profile locking, this pneumatic system is advantageous in that it polishes short and long profiles without intervening manually on the strokes
