Enhanced safety attachment for cutting machine

The safety attachment provides preferably 4 video cameras mounted around a bandsaw blade and looking parallel to the blade direction. Each camera CCD sensor is partly scanned in mode 1. In mode 1 an axis corner of each scanned area is aligned with the camera axis, produced to the table, defining a c...

Zusammenfassung:	The safety attachment provides preferably 4 video cameras mounted around a bandsaw blade and looking parallel to the blade direction. Each camera CCD sensor is partly scanned in mode 1. In mode 1 an axis corner of each scanned area is aligned with the camera axis, produced to the table, defining a corner of a parallel-sided protected volume including the entire exposed blade. The blade is rapidly braked when the attachment detects a glove intrusion. In the alternative fully scanned mode 2 the protected area extends outside the mode 1 area and a warning only is emitted on intrusion.
