Summary:This disclosure relates to an apparatus for forming from a flat blank a tubular body having a longitudinal side seam. The flat blank is first shaped into the form of an unseamed tubular body, after which the unseamed tubular body is transferred to a transfer mechanism wherein edges of the tubular body to be seamed are moved into spaced relation and thereafter, the expanded unseamed tubular member is moved into position relative to a guide rail whereat the unseamed tubular body is released and the edges thereof are freed to spring back together with the edges engaging the guide rail and positioning the unseamed tubular body with respect thereto. The unseamed tubular body is then moved along the guide rails through a suitable side seam forming mechanism, such as a welding mechanism.
