<p>PURPOSE:To permit the continuous feeding of films without needs to discontinue the feeding by a method in which a carriage is moved by the tensile force of a continuous film put between holders and the continuous film is heat-sealed by a heat sealer. CONSTITUTION:When an air cylinder 15 is driven and upper plates 8H and 9H are lowered, a continuous double bag is put between pairs of plates 8H and 8L and 9H and 9L. The tensile force of the continuous bag 1 is transmitted to the plates 8H, 8L, 9H, and 9L and the carriage 10, and the carriage 10 is moved in the feeding direction of the bag 1 and heaters 7H and 7L are also moved integrally with the carriage 10, where the feeding speeds of the continuous film 1 are equalized. Afterwards, the air cylinders 11H and 11L of the heaters 7H and 7L are driven and the bag 1 is put between the heaters 7H and 7L. The bag 1 can thus be put between the heaters 7H and 7L, the continuous inner bag 3 can be heat-sealed, and the bag 1 can be fed continuously.</p> |
