DEFINITION

Classification: 428/116

(under subclass 98) Product comprising a layer or component including either discrete elements (e.g., tubular constituents) or components which form or cooperate to form, cavities the longitudinal axes of which are at an angle to the plane of the web or sheet.

(1) Note. An integral layer (e.g., molded or apertured layer) including curvilinear or polygonal through openings therein is not considered to fall within the definition of this subclass. See particularly subclasses 131+ below.

SEE OR SEARCH THIS CLASS, SUBCLASS:

131+, for a web or sheet embodying an apertured component (e.g. layer with through openings, expanded metal, etc.) and particularly indented subclasses 132+ where such component comprises struck-out portions.

156+, for a web or sheet embodying a component of varying thickness (e.g., layer with open cavities) and especially subclass 161 for such component cooperating with a second component to form inter-laminar spaces.

174+, for a web or sheet embodying a nonplanar component and

especially subclasses 178 and 180 where such component cooperates with a second component to form closed cells. 188, for a web or sheet including a longitudinally or transversely extending tubular cavity or cell.

593, for corresponding metallic* honeycomb stock-material*.
