(To make up for the shortage of material from manufacturing) There are many reasons that manufacturing will ignore the protests of the winder operator They do not understand the physics They do not want to acknowledge the fact that they are the root of the problem They hide behind the flimsy shields of “The scanner/test lab gage measurements do not show troubled rolls.” “We are in spec.” “It’s the best we can do.” Thus, getting absolutely no satisfaction and probably no sympathy either from extrusion, coating or whoever is responsible, the winder operator is back where they started. Now, they only have one card left to play to reduce waste levels: differential winding. With differential winding, also called slipped core winding, each roll can turn at its own RPM, is independently torqued and thus independently tensioned.
