ABSTRACT:
A device is provided for feeding horizontally oriented packages or bags at a regular interval to a zipper profile attaching device. The loose packages or bags are placed onto a servo-driven lugged chain conveyor wherein the lugs are evenly spaced at the nominal desired center-to-center spacing of the packages or bags. The servo-driven lugged chain conveyor feeds the packages or bags to be captured between upper and lower secondary constant velocity conveyors. The lower secondary constant velocity conveyor includes an encoder which is used to slave the servo of the servo-driven lugged chain conveyor, with an adjustable programmable ratio. This achieves a consistent center-to-center distance of the horizontally oriented packages or bags which are then fed to a zipper profile attaching device.
