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. A shape of the contact face can define a major central axis that is non-perpendicular and non-parallel with the direction of transport.

Abstract: A roll of multilayer optical film is described. The roll includes a substantially uniaxially-oriented multilayer optical film, where at least one layer of the multilayer optical film has indices of refraction in a length direction and a thickness direction that are substantially the same, but substantially different from an index of refraction in a width direction.

Abstract: A multilayer optical film includes a plurality of alternating polymeric first and second layers numbering at least 20 in total. The polymeric first layers include between about 10% and 50% by weight of polyethylene terephthalate and between about 50% and 90% by weight of polyethylene naphthalate. For a substantially normally incident light and for a visible wavelength range, the multilayer optical film has respective average optical transmissions of between about 10% and 30% when the incident light is polarized along a first direction and greater than about 60% when the incident light is polarized along an in-plane orthogonal second direction. For a p-polarized incident light and for at least one wavelength in an infrared wavelength range, the multilayer optical film has optical transmissions T1 and T2 for respective incident angles of less than about 10 degrees and greater than about 40 degrees, wherein T2−T1 is less than about 40%.
