Abstract

A placement component rapidly moves individual bag blanks from a pack or magazine to a conveyor system in uniformly spaced relationship. Each bag blank has opposite surfaces. While the conveyor system continues to move the bags, opening tabs are automatically applied to opposite surfaces of each bag, followed by high speed application and cutting of sideways extending flexible closure strips. The bag blanks are moved continuously from the placement component to the high speed cutting section, as compared to incremental movement, for high speed manufacturing of specialized bags.
