ABSTRACT:
This application discloses a method and apparatus for converting thermoplastic web material, flat or tubular, to produce bags. A conventional bag machine produces web segments provided with a group of centrally located holes and each segment is transferred by a conventional rotary transfer device to one of a plurality of platforms which are sequentially located at a stacking station. The platforms are provided with upwardly projecting pins on which the web sections are stacked. After the accumulation of a desired number of web segments on the platform located at the stacking station, the loaded platform is indexed away from the stacking station to a perforating station and then to a cutting or cutting and blocking station to thereby produce two bag stacks, each of which are retained on the associated platform by the pins.
