Means, secondary polymerization means, and primary cutting means, and the post-process portion comprises secondary cutting means, delivery means, tri-fold means, and sealing means.
Both the primary cutting means and the secondary cutting means are composed of a rotating roll and a cutter, and the dynamic inertia during operation is always in one direction, so that energy loss is extremely small and high-speed operation is possible. , Can increase productivity. Then, the main body of the panty liner is manufactured in the pre-process portion, and the three-fold packaging is performed in the post-process portion. That is, 2
Since the panty liner body and the release film are temporarily bonded and integrated by the next cutting means, the panty liner body and the release film are individually separated by three-fold means for folding in three and sealing means for heat-sealing both side edges of the release film. Since there is no need to handle it and it is sufficient to handle it as an integral object, the work content is simplified, and the work can be performed accurately and quickly. For this reason, the tri-fold sealing operation can be performed in one continuous process, and the operation process is greatly simplified.
