DEFINITION

Classification: 428/141

(under subclass 98) Product in which an area of the web or sheet has a structure which extends substantially across the area but which is made up of pits, depressions, furrows or other such irregularities of no regular design or pattern, so as to give the surface a design or pattern, so as to give the surface a desired feel or texture and which area may be (1) exposed or (2) covered with a layer designed to permit light to pass therethrough and render the area visible or (3) covered with a material which is opaque but designed to protect the area from injury.

(1) Note. The difference between this subclass and 156+ is that in the latter, the layer is desired to vary in thickness, while in the present subclass there is no substantial variation in thickness except merely that necessitated by virtue of the surface irregularities.

(2) Note. Excluded from this and the indented subclasses are products which are knitted, braided, woven, etc. The surface characteristics of such products are considered to be uniform and regular or patterned, not irregular, as required by subclasses 141+.

(3) Note. Excluded from this and the indented subclasses are products in which the textured surface is provided solely for bonding two layers to one another through the textured surface. This will be classified below on other features such as the compositions of the layers.

SEE OR SEARCH THIS CLASS, SUBCLASS:

85+, for a surface which is made up of looped filamentary material or free ended material extending from and integral with the surface of a web or sheet, resulting in a bristly, fuzzy or resilient surface.

156+, for a web or sheet in which a layer or component varies in thickness across its width or length.
