Method and apparatus for making material with a fusible backing
 A material with a fusible backing is made by bringing a substrate into contact with the outside of a rotatable printing screen having fine fusible polymer dust supplied to its inner side and then bringing the substrate out of contact with the screen and heating it from below to fuse the polymer to the substrate. The amount of dust falling out of the screen onto the substrate after the substrate leaves the screen is controlled by suctioning off a portion of the falling dust.
