Stretching Or Stretch Forming Patents (Class 264/291)
  • Patent number: 8579621
    Abstract: Provided is a method for manufacturing a high-quality porous film. Here, while the porous film is being manufactured through forming micropores by stretching, a raw film is prevented from slipping on the surfaces of the respective rolls as much as possible even though the raw film includes oil or liquid paraffin as a solvent. The method is for manufacturing a porous film through forming micropores by successive biaxial stretching. A tensile force applied to the raw film F transferring from the longitudinal stretching machine (10) to the transverse stretching machine (50) is set not less than a stretching force necessary for the longitudinal stretching, and thus the raw film is prevented from slipping on a contact surface between the raw film and each roll of the longitudinal stretching machine (10).

  • Patent number: 8252218
    Abstract: Provided is a method for manufacturing a high-quality porous film. Here, while the porous film is being manufactured through forming micropores by stretching, a raw film is prevented from slipping on the surfaces of the respective rolls as much as possible even though the raw film includes oil or liquid paraffin as a solvent. The method is for manufacturing a porous film through forming micropores by successive biaxial stretching. A tensile force applied to the raw film F transferring from the longitudinal stretching machine (10) to the transverse stretching machine (50) is set not less than a stretching force necessary for the longitudinal stretching, and thus the raw film is prevented from slipping on a contact surface between the raw film and each roll of the longitudinal stretching machine (10).
