Apparatus for feeding and withdrawing a support member for a fusing operation of film end portions in film packaging is described wherein sheet member is interspersed between the support member and the film in the fusion position. The sheet member is normally out of contact with the support member until the support member is moved into the fusion position. When the support member is moved from the fusion position back to the normal position, the sheet member prevents the support member from entering into frictional engagement with the film. The sheet member may be arranged on both the front and rear surfaces of the support member so that damage is avoided due to direct contact between the support member and both the film and the article being packaged.
