Abstract

MéTODOS PARA REDUZIR EMPENO EM MADEIRA SERRADA DERIVADA DE UMA TORA, E PARA OTIMIZAR COMERCIALIZAçãO DE TRONCO São providos métodos para reduzir potencial de empeno de madeira serrada derivada de uma matéria-prima, tais como uma tora ou tronco. Os métodos envolvem examinar a tora ou tronco com relação a propriedades de contração e/ou propriedades de grã espiralada. A localização das propriedades de contração e/ou propriedades de grã espiralada determina como a tora está orientada em relação a um dispositivo de corte. Em uma outra modalidade, essas características determinam qual padrão de corte é selecionado para criar a madeira serrada. No caso de um tronco, essas características determinam como o tronco será seccionado.
