    • A knife holder (402) for a tube cutting unit is adapted to receiving a rotating tube fed out from a tube manufacturing device in a feed direction (316). The feed direction is parallel with the tube's longitudinal direction and the rotation takes place about an axis in the tube's longitudinal direction. The knife holder is adapted to following the rotating tube in the latter's longitudinal direction and to bringing a knife element into contact with the tube in a cutting direction and thereby creating in the rotating tube a cut at right angles to the longitudinal direction of the tube. The knife holder is further provided with at least a first bearing element (414) and a second bearing element (415) configured to engage in respective brackets (416, 417) in the tube cutting unit. The bearing elements are so disposed relative to one another that the perpendicular direction (464) to a plane (462), which plane runs in the cutting direction through the bearing elements, and the longitudinal direction of the tube deviate from being parallel.
    • 用于管切割单元的刀保持器(402)适于接收沿进给方向(316)从管制造装置送出的旋转管。 进给方向与管的纵向平行,并且围绕管的纵向方向的轴线进行旋转。 刀架适于在后者的纵向方向上跟随旋转管,并使刀元件沿切割方向与管接触,从而在旋转管中产生与管的纵向方向成直角的切口。 刀架还设置有至少第一轴承元件(414)和第二轴承元件(415),该第二轴承元件构造成与管切割单元中的相应托架(416,417)啮合。 轴承元件相对于彼此设置成使得垂直方向(464)到平面(462),该平面(462),该平面在切割方向上通过轴承元件延伸,并且管的纵向方向偏离平行。
