    • In the manufacture of multichamber tubular containers it has been found that the inner divider walls should be bonded to the exterior wall by means of a band sealing method. In the band sealing method there is a band that contacts the upper film and a band that contacts the lower film that are to be bonded. In the present processes the upper band contacts the inner divider wall while the lower band contacts the exterior surface of the outer wall of the tubular container. In order to prevent the marring or otherwise putting a defect into the exterior surface of the outer wall the temperature of the lower band is maintained at a lower temperature than the upper band. This will decrease the temperature of the exterior surface of the outer wall and prevent imperfections in the exterior surface of the outer wall. The advantage is a multichamber tubular container without any imperfections in the exterior surface. This enhances the overall appearance of the tubular container.
    • 已经发现在多室管状容器的制造中,内分隔壁应通过带密封方法结合到外壁。 在带密封方法中,存在与上部膜接触的带和与被接合的下部膜接触的带。 在本方法中,上带接触内分隔壁,而下带接触管状容器的外壁的外表面。 为了防止损坏或以其他方式将缺陷引入外壁的外表面,下带的温度保持在比上带更低的温度。 这将降低外壁的外表面的温度并防止外壁的外表面的缺陷。 优点是多室管状容器在外表面上没有任何缺陷。 这增强了管状容器的整体外观。
