  • Publication number: 20170165859
    Abstract: The device serves to separate flexible packaging products (4) that have been cut out from a web (3), more particularly packaging bags, from waste parts (5). To this end, a transport device (1) for transporting the web (3) along a transport path (2) and a workstation (8) for cutting out the packaging products (4) from the web (3) are provided. The transport device (1) is provided with means (14, 23) for selectively retaining and releasing packaging products (4) and waste parts (5). Further workstations (9 to 12) are arranged along the transport path (2), at least one of which is provided with means for selectively picking up packaging products (4) and waste parts (5), respectively, that are located on the transport device (1). It is thus achieved that both the packaging products (4) and the waste parts (5) are always retained until they are laid down in a container intended therefor and are never in an uncontrolled state.
