Abstract
The present invention relates to a method for making pouches providing a continuous web; folding the web to provide confronting side surfaces joined along a bottom edge; forming a vertical seal between the confronting side surfaces, thereby providing a series of adjacent pockets having opposite side walls with each pocket having an unsealed opening along a top edge; filling the pockets through the unsealed opening with material; sealing the unsealed opening. In the inventive method, which facilitates handling of the continuous web forming the pouches, the web is perforated by a perforation between a leading length piece of the web adapted to form a leading pocket and a trailing length piece of the web adapted to form a trailing pocket, and the distance between a trailing edge of the leading length piece and a leading edge of a trailing length piece is increased for tearing the leading and the trailing lengths pieces apart at the perforation.
