Zusammenfassung:	A method and apparatus for fabricating a resin impregnable flexible liner for lining a lateral pipe which leads into a main pipe having at one end a flexible collar for installation at the location where the lateral liner meets the main is provided. The seal is formed using a pipe template with an opening conforming to the lateral to be sealed. A tubular portion of liner is inserted into the opening and a ring of flexible impregnable material is bonded to the tubular portion about the opening. An expandable plug holds the elements in position during bonding.
