  • Patent number: 10583603
    Abstract: A film (50) processing apparatus (20) including a film stretching device (22) and a take-away device (24) and a film processing method using the apparatus. The take-away device receives the film after the stretching device and transports the film along a conveying region in a direction of transport (X). The take-away device includes opposing, first and second conveyor assemblies. The first conveyor assembly has a continuous belt driving a plurality of discrete pads (180a, 180b). Each pad forms a contact face (194a, 194b) extending between leading (200b) and trailing edges (202a). The pads are configured and arranged such that the trailing edge (202a) of a first pad (180a) overlaps the leading edge (200b) of an immediately adjacent second pad (180b) as the first and second pads traverse the conveying region. The overlap is characterized by a line (322) perpendicular to the direction of transport passing at any given moment through the first and second pads.

  • Publication number: 20100254002
    Abstract: A stretcher for substantially uniaxially orienting a film includes a plurality of gripping members to hold opposing edge portions of the film, paths along which the gripping members travel to stretch the film in a stretching region, and a drive mechanism to convey the film and gripping members along a machine direction. At least a portion of the paths in the stretching region define diverging, curvilinear courses disposed in-plane. The paths are configured such that during the stretching an extent of uniaxial character, U, is between zero and unity and a minimum value of an extent of uniaxial character, U, is at least 0.70 over a final portion of the stretching after achieving a TDDR of 2.5. U is defined as U=(1/MDDR?1)/(TDDR1/2?1), wherein TDDR is greater than 4 at an end of the stretching region.

  • Patent number: 7037461
    Abstract: A method of stretching films in which all or a portion of the width of the film is cooled during or just after stretching so as to improve the uniformity of the film. The includes stretching a polymeric film in a tenter that grasps the film with a plurality of clips along the opposing edges of the film and propels the clips to thereby stretch the film. The tenter includes driven clips and idler clips, with at least one idler clip between respective pairs of driven clips. The cooling is done so as to improve the uniformity of the clip spacing relative to the spacing obtained at otherwise identical process conditions without such cooling.
