Abstract
A system for providing vacuum to a moving element of a transport system, the system including a vacuum chamber on the moving element for storing vacuum, a vacuum source, and a vacuum inlet provided on the vacuum chamber for connection to the vacuum source. The system further includes a vacuum outlet in communication with the vacuum chamber and positioned on the moving element. The vacuum source may be provided on and travel with the moving element or on the transport system and periodically engage with the vacuum chamber. Where the vacuum source is provided on the moving element, a vacuum chamber may not be required. Further, the vacuum source may be driven by electrical energy and/or mechanical energy in various configurations.
