    Abstract: The invention relates to a chipper knife with at least one cutting edge (6) along at least one of its side edges. The chipper knife is adapted to be mounted in chippers of the kind which are used to cut chips of a desired size and shape from pieces of wood or timber (7) and which comprise a tool, in the form of a plane or conical disc, which is arranged for rotation about an axis of rotation and on which a plurality of such chipper knifes (2) are mountable in such manner that one end of the cutting edge of the chipper knife is located closer to the axis of rotation of the tool than the opposite end of the cutting edge. The cutting edge (6) of the chipper knife is formed between a timber-guiding surface and a chip-guiding surface, the timber-guiding surface having a varying angle along its length in relation to a plane of rotation in such a way that the angle is greater at the end of the cutting edge located closest to the axis of rotation decreases in the outward direction. The chip-guiding surface of the chipper knife also has a varying angle along its length in relation to a plane of rotation in such a way that the angle is smaller at the end of the cutting edge located closest to the axis of rotation and increases in the outward direction in order to obtain a cutting edge angle between the timber-guiding surface and the chip-guiding surface (13) that is essentially constant along the whole length of the cutting edge.

    Abstract translation: 本发明涉及一种具有沿着其至少一个侧边缘的至少一个切割刃(6)的切片刀。 切片刀适于安装在用于从木材或木材(7)切割所需尺寸和形状的切屑的切片机中,并且其包括平面或圆锥形盘形式的工具, 其布置成围绕旋转轴线旋转,并且多个这样的切片刀(2)可以以这样的方式安装在其上,使得切片刀的切割刃的一端位于比刀具的旋转轴线更靠近刀具的旋转轴线的位置, 刀刃的相对端。 切片刀的切割刃(6)形成在木材引导表面和切屑引导表面之间,木材引导表面沿其长度相对于旋转平面具有变化的角度,使得 在最靠近旋转轴线的切割边缘的端部处的角度在向外方向上减小。 切屑刀的切屑引导表面也具有相对于旋转平面沿其长度变化的角度,使得角度在最靠近旋转轴线的切削刃的端部处较小,并且增加 向外的方向,以便在木材引导表面和切屑引导表面(13)之间获得沿切削刃的整个长度基本恒定的切割角度。

    Abstract: The invention relates to a method for forming a round log into a block with two or more flat lateral surfaces. IN the forming, the material to be removed is cut directly into chips in a block-forming assembly which comprises two or more working tools (3). Each of the working tools has the form of a rotary drum or frustoconical body, which on its circumferential surface carries a plurality of chipper knives (4). After the block-forming assembly, the block is fed to a sawing assembly for resawing, and when sawing thick logs the feed rate of the sawing assembly and, thus, also of the block-forming assembly must be reduced. According to the invention, the method comprises removing one or more chipper knives (4) from each of the working tools (3) when sawing thick logs. As a result, the reduction of the rotary speed of the working tools is avoided or limited, which is otherwise necessary to keep the desired chip size. The invention also concerns a blind knife (10) to be mounted in a chipper knife seat (11) instead of a removed chipper knife.

    Abstract translation: 本发明涉及一种用于形成具有两个或多个平坦侧表面的块的圆形木材的方法。 在成形中,要被去除的材料直接切割成块状成形组件,其中包括两个或更多个工作工具(3)。 每个工作工具具有旋转滚筒或截头圆锥体的形式,其圆周表面上装有多个切片刀(4)。 在块形成组件之后,块被馈送到锯切组件以进行解嵌,并且当锯切厚木时,必须减小锯切组件的进给速率,因此还必须减小块形成组件的进给速率。 根据本发明,该方法包括当锯切厚原木时,从每个加工工具(3)中移除一个或多个切屑刀(4)。 结果,避免或限制了工作工具的转速的降低,否则为了保持期望的芯片尺寸是必需的。 本发明还涉及一种安装在切片刀座(11)中的盲刀(10),而不是去除切刀。
