Abstract:

A system for detecting a jam condition in a series of sequentially moving members which are passing a plurality of stations. The system finds particular application in the production of corrugated board or the like in which at the first station there may be a slitting or slotting or printing drum which is performing an operation on a series of moving corrugated board members. There are detection means at each station and successive signals from one station indicating the presence of a member at that station without a resetting signal from the next sequential station will provide a signal indicative of a jam condition. There are means to prevent a false indication of a jam which can be caused by the absence of a member at the first station in the system.
