Abstract:
A folding jaw cylinder comprising:at least one folding jaw including first and second folding jaw elements, said first and second folding jaw elements defining a folding jaw gap having a gap distance, said first and second folding jaw elements being operable to selectively grasp and release a product placed in said folding jaw gap; means supporting each of said first and second folding jaw elements on the folding jaw cylinder for movement relative to each other to vary said folding jaw gap distance defined by said first and second folding jaw elements; and means for shifting at least one of said first and second relatively movable folding jaw elements on the folding jaw cylinder with respect to the other of said relatively movable first and second folding jaw elements to vary said folding jaw gap distance defined by said first and second folding jaw elements in response to a force generated between said first and second folding jaw elements, said force between said first and second folding jaw elements being generated by a thickness of a product received in said folding jaw gap defined by said first and second folding jaw elements, said force increasing with an increase of said thickness of a product received in said folding jaw gap.
