Trapezoid strip shaping process involves cutting parallel strips from core region of round timber, and dividing into triangular-section strips

摘要

The trapezoid strip shaping process produces strips for use in building up a beam (8). Starting from the round timber, the core regions is sawn into parallel pieces, The arc-shaped blanks are then divided into a number of triangular-section strips without core regions. They may be placed asymmetrically in the beam so that there is no common cut point.
