    • An adjustable diameter tape roll cartridge core assembly which permits various different tape rolls, manufactured, for example, by various different tape roll manufacturers, and characterized by different internal diameter dimensions, to be fixedly and securedly mounted upon the tape roll cartridge core member of a tape roll dispensing cartridge assembly of a carton or case sealing machine. The core assembly comprises an expandable and contractible annular ring member whereby the external diametrical extent of such expandable and contractible annular ring member is adjustable so as to in fact be capable of tightly engaging the inner peripheral surface portion of any one of various different tape rolls having various different internal diameter dimensions.

    • A method of manufacturing a polarized optical element comprises the steps of: providing a polarizing film comprising free hydroxyl groups; placing the polarizing film within a mold cavity: admitting into the mold cavity a liquid-phase polyurethane-based optical material containing —NCO functional groups reactive with said hydroxyl groups and comprising the following components: A) a liquid polyisocyanate or polyisocyanate prepolymer having a content of —NCO functional groups comprised between 5 and 50% by weight and an average functionality of 2 to 3, B) an isocyanate-reactive component comprising at least one organic compound containing at least two aromatic amine groups, and C) at least one organometallic catalyst; curing the liquid-phase polyurethane-based optical material to form a polarized optical element. The method allows to reliably manufacture a polarized optical element comprising an optical part made of polyurethane-based optical material and a polarizing film integrally bonded to the optical part even using thin freestanding polarizing films, such as PVA films, achieving at the same time improved adhesion properties of the polarizing film to the optical material.
