Abstract
The invention is meant for a cant forming arrangement of the kind with at least two rotational chipping heads with a basic cut off conical form where they each have a basic conical main surface and a small end, whereby the chipping heads are arranged in pairs with the small ends turned opposing one another and equipped with replaceable knives which are arranged on the respective chipping head's main face with the purpose to surface a log on two opposing sides, through length feeding of a log between the chipping heads, while they are rotating, and that the wood which is removed is made directly to chips by the knives. A single knife in at least one spiral set of cutting knives closest to the chipping head's small end, shows a main angled cutting edge which, besides that it in a known way extends substantially parallel with a rotational plane to the chipping heads, is angled 10 to 50 degrees back in relation to a radius through the rotation center and the chipping heads, in such a way that an outer, from the rotational center furthest away end of the main cutting edge is located further back towards the rotational direction in relation to an inner, closer to the rotational center lo…
