Tool to clean heat treatment tubes in fast synthetic thread spinning

摘要

An apparatus for cleaning tubes used in a heater device for the heat treatment of running threads is a cylindrical shell (14, 15, 20) which has an outer diameter (19) slightly larger than the inner diameter of the heat treatment tube (7). A slot (18) extends over at least part of the shell length starting from its front end face (22), and on its opposite rear face (23) it is equipped with an extension (16, 20) for connecting and disconnecting a driving rod.
