The invention relates to an apparatus for transversely sealing packages in which transverse seals are applied to a continuous length of tubular member, in a direction transverse to the length thereof when the tubular member contains a filling such as beverage, whereby an enclosed package is formed between adjacent transverse seals. A plurality of carrier means which operate to hold the tubular member and apply transverse seals is disposed around a rotatable body which is adapted to be continuously driven for rotation. Each of the carrier means includes an inner mold and an outer mold which are disposed inward and outward as viewed in the radial direction of the rotatable body, and the outer mold can be closed against the inner mold or moved to its open position. The tubular member is continuously supplied to the inner mold in the open position of the outer mold, and a transverse seal is applied thereto while it is held between the inner mold and the outer mold. The tubular member is then removed out of the inner mold when the outer mold assumes its open position. In this manner, a high speed operation is enabled while assuring a sufficient length of time during which the tubular member is held in the carrier means to apply a transverse seal in accordance with a printed pattern on the member in a reliable manner.
