Abstract
Apparatus for producing handled bags includes a web dispenser; a perforator for creating perforated seams transversely across the web at predetermined intervals to generate a succession of adjacent web sections; means for attaching at least one handle to each web section; a tube forming mechanism for configuring the web into a tubular configuration; a separating device for breaking the perforated seams to separate the adjacent web sections without disturbing the handles; and a bottom forming mechanism for closing the bottom end of each separated web section. The separating device includes a rotatable first breaker roll having a pressure bar provided thereon and a rotatable second breaker roll having a cooperating gap formed therein for receiving the pressure bar as the first and second breaker rolls are synchronously rotated with the web fed therebetween. The pressure bar includes a contoured edge surface with relief notches appropriately formed therein to receive the handles; and the cooperating gap includes angled sidewalls and is provided with a resilient material therein. A method for performing various steps in accordance with the elements of the apparatus is also included.
