Abstract
This invention relates to a transverse sealing mechanism for use in producing bag-packed products by packing products in tubular film. The transverse sealing mechanism comprises compression-and-heat sealing means and compression-cooling and compression-cutting means disposed immediately below said sealing means, each of these means having a mechanism which can increase its compressive force infinitely. The packed bag transverse sealing mechanism provides for storing and perfect seals.
