PRODUCT-OUT-OF-REGISTRATION CONTROL FOR HIGH SPEED WRAPPING MACHINE ABSTRACT OF THE DISCLOSURE A method and apparatus for increasing the performance and through-put of a high speed horizontal wrapping machine of the type having mechanically independently driven infeed, film drive and cut/seal head motors, each controlled by a shared programmed microprocessor whereby in the event that a product to be wrapped gets out of registration to the point where the machine's cut/seal head blades might otherwise engage the product being wrapped rather than only the film between two adjacent products, the condition is sensed and a software routine is called which causes the cut/seal heads to come to a stop in the open condition while the film tube continues to be fed until all the products, including the one out of registration and all those downstream from it, exit the wrapper, at which point the wrapper resumes its normal running mode. In this fashion, damage to the cut/seal head and associated down-time to clear the jam is avoided.
