Abstract
Abstract Apparatus and methods for the manufacture of tubular containers of the type comprising a tubular body of flexible packaging material joined to an end closure member wherein the end closure member is first supported on a mandrel, a flat sheet of the body material is fed to the mandrel and folded into a tube around the end closure member and thereafter joined thereto to form a completed container. As a further feature, the apparatus may include means for thermally reflowing a portion of the end closure member if it is of a construction which includes a radially-extending flange that is thermally reflowable to the final position in which it is disposed axially of the container body.
