摘要： A method for manufacturing a plywood panel (150). The method comprises peeling a secondary peeler log (100b) with the veneer lathe (200) to form a secondary veneer (110b); cutting the secondary veneer (110b) to form veneer sheets (120); drying the secondary veneer (110b) and/or the veneer sheets (120); stacking veneer sheets (120) on to each other and arranging adhesive (144) in between veneer sheets (120) to form a veneer sheet stack (130); and pressing the veneer sheet stack (130) to form the plywood panel (150). The method further comprises peeling a primary peeler log (100a) with a veneer lathe (200) to form a primary veneer (110a); imaging a surface (112) of the primary veneer (110a) with an imaging device (310) to form a first signal (S 1 ) indicative of a profile of the surface (112) of the primary veneer (110a); and by using the first signal (Si), determining that the surface (112) of the primary veneer (110a) has a peeling defect (114). In addition, a system configured to perform the method.
