Beschreibung
Zusammenfassung:	This application discloses a method and apparatus for converting thermoplastic web material, flat or tubular, to produce bags. A bag machine produces web segments provided with a group of centrally located holes (54) and each segment is transferred by a rotary transfer device (44) to one of a plurality of platforms (50) which are sequentially located at a stacking station (52). The platforms are provided with upwardly projecting pins (56) on which the web sections (WS) are stacked. After the accumulation of a desired number of web segments on the platform (50) located at the stacking station, the loaded platform is indexed away from the stacking station to a perforating station (62) and then to a cutting or cutting and blocking station (64) to thereby produce two bag stacks, each of which are retained on the associated platform by the pins.
