Wrapping machine for layered vessels

A wrapping machine for use in constructing layered vessels having at least one layer formed of adjoining vessel sections wherein vessel sections are welded together along adjoining longitudinal edges thereof by weldments, comprising:

• band means adapted to encircle sections of the layered vessel for positioning the vessel sections adjacent one another on a layer therebelow for forming one layer of the layered vessel;
• tightening means for tightening said band means about the adjoining vessel sections to insure close engagement of the adjoining vessel sections with the outer surface of the layer therebelow;
• said band means being interlooped for applying concentric loading of the layered vessel by said tightening means when drawing the vessel sections together;
• and,
• anti-galling means for preventing galling of said band means by the longitudinal edges of the vessel sections or weldments thereof as said tightening means constricts said band means about the vessel sections, said anti-galling means mounted with said band means.
