摘要： A paperboard core suitable for use in winding yarns may include strips of paperboard wrapped about an axis and secured together to form an elongate structure defining a winding surface. A coating of a polymer such as polyvinylidene chloride covers the winding surface. The coating may be applied to the strips of paperboard prior to winding and/or applied to the winding surface after winding. The coating may comprise multiple layers of the polymer, which may be cured individually. The coating may also be applied so as to create a substantially uninterrupted coating along the winding surface. One method of applying the coating is by roll-coating.

摘要： The invention relates to a device for the production of a complex film, comprising a plurality of feed means (100, 200, 300) for single-layer or multilayered films, means for driving the films such that they can be unwound, and means (400, 410) for superposing the films coming from the various feed means in order to form a complex, characterized in that the inventive device comprises a moveable support (190; 290; 390) on which at least one of the feed means (100; 200; 300) of one of the films is fixed, said moveable support (190; 290; 390) being able to oscillate about an axis (101; 201; 301) in order to modify the lateral positioning of the film in relation to the other films in the complex. The invention also relates to a method for the production of an associated complex film structure.
