Abstract

Rivelatori di periferia sono disposti strettamente giustapposti lungo la direzione longitudinale del tronco che deve essere fatto ruotare di un giro attorno ad un centro virtuale, per cui una pluralità di periferie di sezioni trasversali lungo la direzione longitudinale sono rivelate per il tronco. La direzione del cilindro circolare retto più grande viene determinata conformemente ai cerchi inscritti massimi per le periferie di tre sezioni trasversali, cioè quelli adiacenti a entrambe le estremità del tronco e quello a metà del tronco, e il cilindro circolare retto massimo o più grande viene esso stesso determinato conformemente alle periferie di tutte le sezioni trasversali rivelate, per cui la linea centrale di detto cilindro circolare retto massimo viene adottata come il centro di rotazione. Le posizioni di una coppia di travi inclinate o bracci oscillanti sono regolate per annullare la deviazione tra il centro di rotazione e il centro virtuale. Inoltre, il raggio massimo della rotazione del tronco attorno al centro di rotazione è determinato da tutte dette sezioni trasversali rivelate, per cui la tavola della piallatrice è posizionata nella posizione di attesa o riposo in cui la tavola della piallatrice non invade o contrasta mai detto raggio massimo di rotazione del tronco.
