摘要

The invention relates to a knife holder (402) for a tube cutting unit (400), which tube cutting unit (400) is adapted to receiving a rotating tube (2) fed out from a tube manufacturing device (1 ) in a feed direction (316). The feed direction (316) for one length unit is parallel with the longitudinal direction of the tube (2). The rotation of the tube (2) takes place about an axis (310) in the longitudinal direction of the tube (2). The knife holder (402) is configured to be adapted to being movable via bearing elements (414) on the knife holder (402) which communicates with fastening elements (416) disposed on the tube cutting unit (400). The knife holder (402) comprises first and second shaft-bearing parts (410, 412) between which a shaft (408) supporting a knife element (404) with cutting edge (406) is fitted.
