ABSTRACT:
A process for continuously filling a fluid into a plurality of closed bags joined together in the form of an elongated sheet made of two superposed plastics films, the sheet having a baglike flat fluid inlet tube extending longitudinally thereof and formed by heat-sealing the films, the bags being arranged side by side along at least one side of the inlet tube and joined to one another and to the tube, each of the bags being provided inside thereof with a check valve of plastics film adjacent to the tube, the inlet tube being in communication with the bags individually only through a fluid channel of the check valve in each bag. The process comprises the steps of transporting the sheet forward, closing the inlet tube of the sheet by pressing the tube with closing means disposed in the path of transport of the sheet, introducing the fluid into the tube by a fluid supply device having a portion inserted in the tube at a position to the front of the closing means and cutting the tube open longitudinally thereof by a cutter provided on the supply device utilizing the transport of the sheet, filling the bags positioned to the front of the closing means with the fluid introduced into the tube through the check valve, and cutting off a required length of the sheet including the bags filled with the fluid.
