An optical assembly including an optical element insert molded directly onto an optical stack is provided. The optical stack includes an optical film and may include a liner with the optical film being disposed between the optical element and the liner. The liner, if included, is removable from the optical film without substantial damage to the optical film. An outermost layer of the optical film may be diffusion bonded to a major surface of the optical element. The optical film includes a protective coating having an average thickness of no more than 30 micrometers. The protective coating includes an at least partially cured composition. The composition includes 70 to 96 weight percent of urethane (meth)acrylate compound having an average (meth)acrylate functionality of 2 to 9.5, and 2 to 20 weight percent of (meth)acrylate monomer having a (meth)acrylate functionality of 1 to 2.

Optical assembly with protective coating

An optical assembly including an optical element insert molded directly onto an optical stack is provided. The optical stack includes an optical film and may include a liner with the optical film being disposed between the optical element and the liner. The liner, if included, is removable from the optical film without substantial damage to the optical film. An outermost layer of the optical film may be diffusion bonded to a major surface of the optical element.

Optical assembly

A method of making an infrared-reflecting optically transparent assembly comprises: coating a curable composition onto a major surface of an optically transparent thermoplastic polymer film; at least partially curing the curable composition, which may be optionally at least partially dried, to provide a thermoformable composite film; and laminating the thermoformable composite film to an infrared-reflecting multilayer optical film to provide the infrared-reflecting optically transparent assembly. The curable composition comprises urethane (meth)acrylate compound, (meth)acrylate monomer, and silicone (meth)acrylate. The infrared-reflecting optically transparent assembly and methods of including it in an infrared-reflecting lens assembly are also disclosed.

Reinforced articles particularly adapted for use in combination with an adhesive to form reinforced adhesive tape articles that are stretchable as well as hand-tearable along with being highly conformable and cinchable.

Stretchable, hand-tearable, conformable, and cinchable reinforced adhesive tape articles

An article comprising a roll of tape having a coating composition disposed on a first edge face is disclosed herein. A coating composition may be disposed on a second edge face that opposes the first edge face. The coating compositions may be cured. A method for edge coating the roll of tape is also disclosed herein, as well as a method for coating a plurality of articles having different dimensions.

An apparatus for coating an article where the apparatus includes an applicator, a conveyor for sequentially transporting a plurality of articles to the roller and a metering bar positioned against the applicator to meter a predetermined amount of coating composition to the applicator for transfer to an article transported to said applicator by the conveyor.

Coating apparatus

An apparatus and method provides for rotatably cutting and/or laminating layered structures or sheet material supported by webs. A rotary converting apparatus and method of the present invention converts a web comprising a cathode layered structure and a web comprising an anode layered structure into a series of layered electrochemical cell structures supported by a release liner. Employment of a rotary converting process of the present invention provides, among other benefits, for the creation of a product having a finished size, without need for downstream or subsequent cutting.

Rotary converting apparatus and method for laminated products and packaging

A product stacking apparatus and method employs one or more stations, each including a stationary stacking platform or a conveyor upon which spaced-apart pucks are coupled for travel thereon. A product delivery apparatus drives one or more movable webs to which segmented product sheets are removably affixed. The product delivery apparatus includes one or more rotatable lamination interfaces associated with each of the stations for transferring product sheets from the webs to the pucks on a repetitive basis to produce a stack of product sheets on the respective pucks. Each of the segmented product sheets may define all or a portion of an electrochemical cell, all or a portion of a pad including layers of film or sheet material, wherein a portion of each of the layers is provided with a bonding feature, or all or a portion of a pack comprising layers of medical dressing. A puck need not be in motion during the transfer of the product sheet from the lamination roll to the puck. The puck may or may not be attached to a conveyor, but the conveyor need not be in motion during the lamination or stack building process. In this case, a roller is moved across the puck and simultaneously rotated so a point on the surface of the roller interfaces with the puck at the same location on each pass.
