PURPOSE:To make it possible to rapidly and continuously seal an opening of a vessel with a sealing film which is formed from a belt film perforated by an intermittent motion, by heat-sealing the opening of the vessel kept in a vessel holder of a seal head apparatus with said sealing film by a film sealing device. CONSTITUTION:Two transfer tables 9 are arranged. The circulating route A of a film holder 89 is overlapped in a required transfer section D of the film in the circulating route C of a seal head apparatus. The transfer table 9 is intermittently turned by the adsorption of a discontinuously perforated sealing film 5 at air holds 101 on the film holder 89 and synchronously transferred in the film transfer section C at the same speed as the seal head apparatus revolving continuously to securely deliver the sealing film 5 to the film holder of the seal head apparatus. The seal head apparatus holding the sealing film 5 is turned to receive a vessel at a vessel holder and to closely contact the sealing film at the opening 3 of the vessel 1 and further to seal with pressure the opening 3 by a pressing ring 204 and a sub-heater block 205. |
