Tube making mechanism having a fill tube for depositing a ceramic powder into the tube as it is being made

摘要

A fill tube for filling a seam-welded tube with a ceramic powder as the seam-welded tube is being made by a tube making mechanism. The fill tube has a guide tube for directing the ceramic powder from a location upstream of a seam welder to a location downstream of the seam welder. A mounting bracket is attached to the upper end of the guide tube and has a powder channel directing the ceramic powder received from an external powder source into the guide tube and a wire channel directing wires received from an external source into the guide tube. A wire guide is disposed at the opposite end of the guide tube which locates the wires in the seam-welded tube as it is being filled with the ceramic powder.
