ABSTRACT:
In a method of edging boards and of cutting the wane edge of the board into chip form in connection therewith, there is used an edging-mill (2) having a circular sawblade (3) which separates the wane from the board (1) in the form of a so-called rib (1a). Located downstream of the circular sawblade (3) in the feed direction of the board is a chipping module having a cylindrical milling head (15) which is provided with cutters and which is intended to reduce the rib (1a) to chip form. For the purpose of feeding and guiding the board, there is provided between the circular sawblade and the milling head at least one upper and one lower feeding and guiding roller in addition to infeed rollers and outfeed rollers which are located in the feed direction upstream of the circular sawblade and downstream of the milling head respectively.
