Abstract
A method and apparatus for producing an order change in a corrugator machine. A pulse generator is provided on the medium splicer of each single facer in a corrugator machine and on the splicer of a double backer to produce feedlength signals proportional to web material supplied by each splicer. A computer calculates position values which are functions of the relative physical locations of the corrugator machine components, and inventory values which are functions of the relative physical locations and of differences in the feedlength values. The computer then compares feedlength signals and inventory values and as a result of these comparisons, generates sequential control signals to corrugator machine components to produce an order change including a synchronous splice of all web components with a minimum of waste and production downtime.
