    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.

    摘要： The present invention relates to a sorter (1) and a method for sorting wood pieces and for guiding them to a conveyor means (4). This type of sorter comprises a lower frame (2), a receiving deck (6) for wood pieces, and a feeder (7) for detaching a wood piece from the receiving deck. Said feeder comprises control means (8) for supporting the wood piece (5, 51, 52) during movement directed to it and transferring it substantially vertically from the receiving deck. In that case the control means is traversed by at least two bearers (10) controlled by an actuator (11) for producing the vertical movement of the wood piece. The bearers are arranged to project from an outer surface of the control means (8) by an amount of projection that is adjustable during lifting. The feeder (7) further comprises measuring means (12) for detecting a wood piece of the largest cross-sectional diameter on the bearers and for controlling the projection of the bearers to a position corresponding to this diameter.

    摘要： The invention relates to a method for measuring the volume or the end face diameter of a tree trunk and for quality control. The volume is measured in a prior known manner with laser gauges capable of measuring top and butt diameters as well as a length, which are used for calculating a volume. For quality control, the end face of a tree trunk is illuminated with red light and blue light, and light coming from the end face of the tree trunk is received by a color matrix camera (5). From the red/blue ratio in the camera's (5) signals is identified the proportion of rot or other defect in the end face of a tree trunk. The camera signals can be used for calculating the end face diameters of tree trunks. The method is integrated with a pulpwood pretreatment process upstream of debarking.
