ABSTRACT:
Upright pouches are successively severed from the leading end portion of a continuously advancing strip of interconnected pouches by a pair of coacting blades which track the strip and which momentarily move at the same speed as the strip. At that time, one blade is shifted laterally toward the other blade to cut the leading pouch from the strip. Prior to the cutting, a notch is formed in the upper edge portion of the strip between adjacent pouches to impart a desired shape to the upper corners of the pouches and to enable the use of a relatively simple stationary splitter for keeping the two upper edge portions of each pouch separated from one another.
