本发明涉及一种装置（50）用于具有接触侧面中的一个（51）石膏板面板（6）上产生倒角成搁置在广角端（7）的石膏板（6）和连接边缘（52），用于抵靠一窄侧的 石膏板（6）形成的导向凹部（53）和交叉的设备上的多个在一个倒角角度（α），所述导向凹部（53）（50）连接，每一个在相对于支撑侧面的相交的假想线（53“）不同的距离（51） 与轴承侧面（52）具有叶片（54，55,56），其特征在于，所述叶片（54,55，56），每个夹紧出口开口的支承斜面（52）在切割方向上的切削刃之前（54 '55' ，56'）（57 ，58,59）。 根据本发明的窗户ringsumschlossenen的夹紧出口开口形成，其中，在形成位于远离所述支撑边缘肢体的一个窗口（51）延伸的腹板（60）的支承斜面（52）的边缘。

The invention relates to a device (50) for producing a chamfer on a gypsum board panel (6) having one of a contact flank (51) to rest on the wide side (7) of the gypsum board (6) and an attachment edge (52) for bearing against a narrow side of the gypsum board (6) formed guide recess (53) and a plurality in a chamfer angle (α), the guide recess (53) intersecting on the device (50) attached, each at a different distance relative to an imaginary line of intersection (53 ') of the support flank (51) with the bearing flank (52) having blades (54, 55, 56), wherein the bearing flank (52) in the cutting direction before the cutting edges (54 ', 55', 56 ') of the blades (54, 55, 56) each clamping outlet openings (57 , 58, 59). According to the invention the clamping outlet openings of ringsumschlossenen windows are formed, wherein a window of a limb located in remote from the support edge (51) edge of the bearing flank (52) extending web (60) is formed.
