ABSTRACT:
In the manufacture of cylindrical tubes for containers, a foil web and at least one fibre web are helically wound on a heated, rotating mandril. The foil web is wider than the fibre web and its edges lie outside the long edges of the fibre web. The foil web and the fibre web are fed in to the mandril at an angle such that the free edges of the foil web are placed against each other and welded together.
