Our flatmaterial decoilers are controlled absolutely without any contact of the material to the decoiler. The material that has to be feeded to the machine runs between two sensors where it changes the electrostatic field. If more material is needed by the machine the flat material is pulled up and the distance to pole A is reduced. The decoiler begins to uncoil the material. The speed of the swift is proportional to the materials' distance to pole B. As closer the material is to pole A as faster the swift decoils the material to feed the machine. With a regulator the speed can be adapted to the input of the machine. If the machine stops the speed gets reduced till the decoiler stands. The point between the two poles where the speed is zero can be adjusted at the swift.
