The manner of making such a product is, however, classified in this subclass only if it is essentially a process of building-up an assembly of layers of which at least one outer layer is preformed.

It may be deformed out of the flat plane to form a three-dimensional shape. It may or may not be homogeneous or cohesive; it may be an assembly of fibres or pieces of material. It may be discontinuous, e.g. in the form of a grating, honeycomb, or frame.

The term "secured" includes any method of uniting layers, e.g. needling, stitching, gluing, nailing, dovetailing or the interposition of an adhesive or adhesive impregnated support. It may also be an intermediate stage in the production of an article which is not layered in its final form, e.g. a panel with a protective layer that is stripped off when the panel is placed in its position of use. The layers are preformed layers or layers formed IN SITU on a preformed layer and may consist of coherent solid materials, including honeycombs and other cellular materials or of non-coherent solid materials composed of assemblies of strands, strips, fibres, tiles or the like; <br>"filamentary layer" means a layer of threads or filaments of any substance (e.g. wires) of more or less unlimited length placed in an orderly arrangement and secured together; it may be woven, knitted, braided, or netted, or formed of threads crossed or laid side by side and bonded together;<br>"fibrous layer" means a random assembly of fibres or filaments, usually of limited length, e.g. felt, fleece; the fibres being interengaged or connected, e.g. by adhesive. <br>If a layered product is characterised by the way it is produced and not by its structure or composition, the production method should be classified in groups B32B37/00 or B32B38/00, or in subclass B29C, for example in groups B29C45/16 or B29C48/18.<br>In this subclass,<br>The classification of&#160;layered products&#160;is provided for in many classes, most of which are confined to a particular kind of&#160;material.
