Title: Method for producing a business form article
Claims: The invention having thus been described, the following is claimed: 1. A method for producing a continuous business form article, comprising the steps of directing a carrier web along a predetermined path, extruding a continuous film of plastics material onto the web, stretching the film to decresae the thickness of the flim, producing a releasable bond between the film and the carrier web, cutting the film longitudinally in an area releasably bonded to the carrier web and between the marginal edges of the carrier web without cutting the carrier web to form a film strip, releasing and removing the film strip from the carrier web, coating a layer of image transfer material onto at least a portion of the film on the carrier web, and releasing the film and coated layer of image transfer material from the carrier web. 2. A method for producing a continuous business form article, comprising the steps of directing a carrier web along a predetermined path, extruding a continuous thin film of plastics material onto the web, stretching the film to form a film thickness less than 0.0005 inch, producing a releasable bond between the thin film and the carrier web, and between the marginal edges of the carrier web without cutting the carrier web to form a film strip, releasing and removing the film strip from the carrier web, coating a layer of image transfer material onto at least a portion of the film on the carrier web, and releasing the film and coated layer of image transfer material from the carrier web. 3. A method for producing a continuous business form article, comprising the steps of directing a paper web from a supply roll along a predetermined path, extruding a continuous thin film of plastics material onto the web, stretching the film to form a film thickness less than 0.0005 inch, producing a releasable bond between the film and the paper web, trimming at least one edge portion of the film being carried by the web and at a location spaced laterally inwardly of the corresponding edge of the web and without trimming the paper web, releasing and removing the edge portion of the film from the corresponding edge portion of the web, coating a layer of image transfer material onto at least a portion of the film on the paper web, and releasing the film and coated layer of image transfer material from the paper web. 4. A method as defined in claim 1 wherein said step of cutting the film comprises supporting the carrier web with a roller having a resilient outer surface, positioning a circular knife to engage the film in an area adjacent said roller, and rotating the knife at a peripheral speed greater than the linear speed of the carrier web. 5. A method as defined in claim 1 wherein the step of releasing the film and layer of image transfer material from the carrier web comprises the steps of placing an elongated cylindrical rod between the film and the carrier web with the rod extending laterally across the web, and rotating the rod on its axis. 6. A method for producing a continuous business form article, comprising the steps of directing a carrier web along a predetermined path, extruding a continuous film of plastics material onto the web, stretching the film to decrease the thickness of the film, producing a releasable bond between the film and the carrier web, cutting the film longitudinally in an area releasably bonded to the carrier web and between the marginal edges of the carrier web without cutting the carrier web to form a film strip, and releasing and removing the film strip from the carrier web to provide the carrier web with a clean strip free of the film.
