  • Patent number: 5794870
    Abstract: An apparatus for re-rolling a web of plastic bags that has been printed includes first, second and third spindles mounted on a frame. The web from the printer is collected on a spool on the first spindle. This spool with the web is then transferred to the second spindle and then the web from the second spindle is rolled onto the third spindle so that the bags are presented in the proper orientation for subsequent handling such as in a manual bagging operation. The first and third spindles are driven, for examples with separate electric motors.
