Abstract
The present invention concerns a method for forming longitudinal undercut grooves in wood products. It also concerns a cutting blade (5, 12, 14, 15) that could be used in the method. According the invention a longitudinal straight groove (4) is formed in a wooden work piece (1) in a first step, for instance by means of a circular saw blade (2). In a second step the work piece (1) is moved pass the cutting blade (5, 12, 14, 15) to form an undercut groove (7, 8, 9, 10), which undercut groove is either symmetric or asymmetric. The cutting blade (5, 12, 14, 15) has a number of cutting heads (6). The cutting width of the cutting heads increase from a first cutting head (6a) to a last cutting head (6b).
