Abstract: A protective web is releasably laminated to an adhesive-coated stretchable web by continuously drawing the webs at differential degrees of tensile strain into laminating contact in the nip formed by a resilient and a non-resilient roller.

Abstract: A latex paint containing water and one or more higher boiling organic solvents is coated on a carrier film and dried by a process which yields a dried paint layer free of bubble defects. The film is passed continuously through a series of at least three drying stages in contact with warm, moderately humid air and more than half of the heat required for evaporation is supplied to the underside of the film. Drying conditions in at least each of the first three stages are controlled to maintain a film temperature profile which causes the water to evaporate at a moderate rate but more rapidly than the organic solvents, thus achieving coalescence of the paint and avoiding the trapping of liquids in a surface-hardened paint layer.

Abstract: A process for continuous coating of a reactive clearcoat composition on a painted-coated moving plastic film web by means of a laminar flow extrusion coating hopper wherein the reactive components of the composition are fed continuously to a mixing zone and mixed shortly before the composition is coated on the film surface.
