156250, 156257, 156247, 156289, 156353, 156361, 156510, 156577

A method for making a laminate adapted for decorating a substrate including providing (1) a sheet of pre-mask material including a cover layer and a layer of removable adhesive on one surface of the cover layer having an exposed surface defining a first major surface for the sheet of pre-mask material; (2) a supply length of decorative film tape comprising a length of decorative film having opposite first and second major surfaces, and a layer of adhesive along its second major surface; (3) a sheet of release liner having a first major surface adapted to be releasably adhered to by the removable adhesive on the cover layer and by the adhesive on the decorative film; and (4) a tape applicator. One of the sheets is supported with its first major surface in an application plane, and the tape applicator is used to form display lengths of decorative film tape of different predetermined shapes and lengths from the supply length of decorative film tape and to apply those display lengths of decorative film tape to the first major surface of that one of the sheets in a predetermined pattern; after which the first major surface of the other of the sheets is positioned over the surfaces of the display lengths of decorative film tape opposite the first major surface of that one of the sheets. The method adheres the layers of adhesive on the display lengths of decorative film tape to the to the release liner, and adheres the layer of removable adhesive included in the layer of pre-mask material over the first major surfaces of the lengths of decorative film in the display lengths of decorative film tape adhered to the release liner and to the release liner around the display lengths of decorative film tape.

An assemblage of laminates each including only a portion of a graphic, which graphic portion has a layer of pressure-sensitive adhesive along its rear major surface. The graphic portions in the laminates are adapted to be adhered to a substrate by the layers of adhesive in a predetermined relative orientation to form a graphic having a predetermined shape. Each of the laminates further includes a separate polymeric cover sheet having opposite outer and inner major surfaces and overlaying the graphic portion, and a layer of removable pressure-sensitive adhesive having opposite front and rear major surfaces, which layer of removable pressure-sensitive adhesive is coextensive with and has its rear surface adhered to the inner major surface of the cover sheet and has its front surface adhered to the front surface of the graphic portion. The cover sheets in the laminates have irregular visually distinctive mating edges shaped for edge-to-edge engagement only when the graphic portions in the laminates are in the predetermined relative orientation.

A laminate from which decorative films can be precisely applied to a substrate. The laminate includes a polymeric cover sheet having opposite outer and inner major surfaces. A layer of structured pressure sensitive adhesive is adhered to the inner major surface of the cover sheet. The structured pressure sensitive adhesive has a plurality of spaced passageways extending to at least one edge of the layer of structured pressure sensitive adhesive. A decorative film is adhered to the structured pressure sensitive adhesive. A second layer of pressure sensitive adhesive is adhered to the major surfaces of the decorative film opposite the layer of structured pressure sensitive adhesive. A release liner extends substantially across the second layer of pressure sensitive adhesive and a portion of the structured pressure sensitive adhesive.

A spiral wound fiber that includes birefringent interfaces is useful in different optical devices. One type of wound fiber includes at least first and second material layers. At least one of the layers is polymeric and at least one of the layers is birefringent. The spiral wound fiber may be used alone, or in an optical device. Such an optical device can include the fiber embedded within a matrix or attached to a substrate. The spiral wound fiber can be made by rolling a stack of at least two layers, by coextruding the two layers or by coating a rotating form.
