Zero-Speed Splicer

A device found in the infeed section of printing presses used in web offset lithography which splices a fresh roll of paper to an expiring roll.

A zero-speed splicer, in contrast to a flying splicer, operates while the expiring roll and the new roll are both stationary. The press, however, continues to print. This is accomplished by expanding a festoon, or a collapsible series of rollers. While splicing is taking place, the press can draw from the paper snaking its way throiugh the fully-exoanded festoon. The expiring roll is stopped, the new roll is spliced to it, and the new roll is expanded to press speed. This collapses the festoon, which can then be expanded the next time a splice needs to occur.
