    • The invention relates to a knife drum (1, 2) for a machine for cross-cutting lines of material, especially paper or card, comprising a roll-shaped supporting body. Said supporting body consists of two tubular shells (12, 13) arranged above each other concentrically. Said shells consist of fibre composite material. The fibres in the inner shell (12) are rolled crossways to the axis of rotation (11) of the supporting body in a positive and negative angle of 30 DEG to 60 DEG , preferably 45 DEG , and the fibres in the outer shell (13) are rolled in a positive and/or negative angle of less than 30 DEG , preferably less than 10 DEG to the axis of rotation (11) of the supporting body. At least one groove (7) is worked into the cover surface of the outer shell (13) by means of a cutting process, especially milling, said groove extending over the length of the drum. The knife holder (6) is then fixed in the groove.
    • 的叶片滚筒(1,2)用于交叉材料织物的机器,特别是纸或纸板幅材,包括一圆筒形支承体,两个管状,由纤维复合材料制成的同心叠加壳(12,13)构成的。 在30℃的正和负角度的内壳(12)到60℃,优选45°的纤维中,在支承体的旋转(11)的轴线卷绕横向,且在正的纤维在外壳(13)和 /或小于30°,优选小于10 DEG的负角度,支撑体伤口的旋转(11)的轴线。 在外壳的外表面(13)是通过减成法并入,特别是通过铣削,至少一个延伸在所述桶槽(7),在该刀架(6)被固定的长度。
