ABSTRACT:
An apparatus for closing a slider-operated zipper on a moving filled package, comprising means for performing the following steps: conveying a package forward in a straight line; guiding a slider on a zippered portion of the package through a channel as the package moves forward; blocking forward movement of the slider at a predetermined position inside the channel as the package continues to move forward; and releasing the slider when the force being exerted by the slider in the forward direction reaches a level substantially equal to a predetermined threshold. This apparatus can be employed in association with a continuous band sealing apparatus. The means for blocking forward movement of the slider at a predetermined position inside the channel are a pair of spring-loaded plungers, e.g., ball plungers. If the slider end stop is weak, the slider will be pulled off the advancing package and will fall onto an ejection ramp.
