To provide a longitudinal seal tape sealing mechanism, a longitudinal sealing mechanism, and a liquid paper-made container forming device capable of ensuring required heat-seal strength.
In a device for forming a liquid paper-made container covering a joint with a longitudinal seal tape 6, two or more heater heads 4 for heating one edge 1a in the longitudinal direction of a strip-like packaging material 1 are arranged on a longitudinal seal tape sealing mechanism 18 for heat-sealing one edge 1a in the longitudinal direction of the strip-like packaging material 1 to the longitudinal seal tape 6 in series to the flowing direction of the packaging material 1; and two or more heater heads 12 for heating the inner surface of the other edge 1b in the longitudinal direction of a tubular packaging material 11 are arranged on a longitudinal sealing mechanism 26 for heat-sealing one edge 1a and the other edge 1b in the longitudinal direction of the tubular packaging material 11 formed of the strip-like packaging material 1, and the longitudinal seal tape 6 heat-sealed to the one edge 1a and extending from the edge 1a and the other edge 1b in series.
