Latest Patents
Iwai's latest patents include a "Method of and apparatus for manufacturing biaxially oriented film." This invention relates to a method and apparatus that allows for the biaxial orientation of a tubular original film, which is extruded by an extruding die. The process involves heating and injecting air into the film while it is conveyed to nip rolls with individual circumferential speeds. The temperature applied to the film is controlled based on the detected film thickness, ensuring a uniform thickness distribution. Additionally, adjustments can be made to the outer diameter of the bubble-shaped oriented film by modifying the distance between two sets of nip rolls according to the measured width of the film. Another significant patent is the "Method of and apparatus for tubularly drawing thermoplastic resin." This invention describes a method for tubularly drawing a raw material of thermoplastic resin by injecting gas to form a bubble that heats and draws the material.
