Abstract: A method of making a fabric light control window covering in which fabric vanes are adhesively bonded between two sheer fabric sheets such that relative movement between the sheer fabric sheets in a direction perpendicular to the longitudinal direction of the fabric vanes changes the angle of the fabric vanes and, thus, controls the amount of light admitted through the shade. The vanes are bonded to the sheer fabric sheets in a manner which tends to bias the sheer fabric sheets together to the nonlight admitting position. The method features linear application of adhesive to the vane material which provides for a uniform appearance in the finished product. A heat setting process and apparatus is disclosed in which the bonded layers of sheer fabrics and vanes are fed between belts over hot and cool surfaces, under uniform tension and pressure.

Abstract: A process for making a laminated sheet by cutting a fiber-reinforced thermoplastic resin sheet into a plurality of cut sheets. The cut sheets are feed to a butting apparatus to bring adjacent end faces of the cut sheets against each other. The abutted cut sheets are joined to a continuous sheet, which is a fiber-reinforced thermoplastic resin sheet, by melt welding using a heated roller where the cut sheets and the continuous sheet cling to the heated roller. Cooling of the joined cut sheets and continuous sheet occurs by causing such to cling to a cooling roller. A correcting roller is moved along the cooling roller, where the joined cut sheets and continuous sheet are between the cooling roller and the correcting roller, so that the amount of contact arc between the joined cut sheets and continuous sheet is changed to adjust the amount of warp in the joined cut sheets and continuous sheet.

Abstract: A method of making abrasive articles which includes the steps of sandwiching and adhering abrasive particles between two sheets of fiber where the particles have a major cross-section dimension greater than the thickness of the sheets into resultant second sheets. The resultant second sheets are then adhered together by lamination under pressure so that the abrasive particles of a second sheet enter the interstices between the abrasive particles of adjacent other second sheets to form an interlocking bond and increase the tensile strength. The sheets are preferably cut from a processed strip prior to lamination. Prior to lamination the second sheets may be coated with one or both of a liquid rubber and a thermosetting resin. If resin is used the stack is heated as it is pressure laminated. The application of rubber and resin may be in the alternative. The application of rubber imparts flexibility while the resin upon curing imparts hardness.

Abstract: In an absorbent disposable article, such as in particular a diaper, in which an absorbent body is covered on one side by a liquid-impermeable protective sheet and on the opposite side by a porous layer, certain edge areas of the porous cover layer should be provided with a liquid-impermeable protective layer.This protective layer is formed as a prefabricated impervious sheet and possesses, before being placed on cover layer, on one side a smooth and the other side an extremely coarse surface. The impervious sheet serving as the protective layer penetrates essentially exclusively with its coarse surface areas inside the cover layer. Through the smooth side of this impervious sheet, an absolute imperviousness is assured. Because of the physical bond, which forms between the impervious sheet and the cover layer, the impervious sheet can be formed extremely thin, i.e., a minimum amount of material is sufficient for the impervious sheet.

The shaping and detaching of the individual molded articles made of the still warm foil are executed directly after one another at one station, with forming taking place first and detaching then following by means of strip steel cutting, while the form still remains in the closed condition. It is also possible, with the aid of this process, to produce molded articles consisting of two superimposed foils with layers of an absorbent material disposed therebetween.

Abstract: The present invention is a method and apparatus for making a diaper having one or more elastic margins. The diaper uses for the entire moisture permeable backing sheet an elastomeric material of the type that is heat unstable and relatively inelastic in its unshrunk form and stable and relatively elastic in its heat shrunk form. Diapers made using one of these materials as a backing sheet can be conventionally assembled. After assembly, the marginal areas, which may be either or both of the transverse and longitudinal margins, may be heated to a sufficient temperature for shrinkage to occur in the backing sheet. This shrinkage will only occur when the backing sheet is unrestrained. The method provides for the maintenance of longitudinal tension in the central portion of an end-to-end assembly of diaper units while relaxing the edge tension on the units.
