COOPERATIVE PATENT CLASSIFICATION

LAYERED PRODUCTS, i.e. PRODUCTS BUILT-UP OF STRATA OF FLAT OR NON-FLAT, e.g. CELLULAR OR HONEYCOMB, FORM
NOTE
-
This subclass covers:
- layered products comprising different kinds of material or
layered products not characterised by the particular kind
of material used;
- a product similar to a layered product but comprising only
material in the form of a sheet or network embedded in a
mass of plastics or of physically-similar substances which
mass penetrates the said sheet or network and lies on both
sides of the latter (e.g. so that the sheet or network
reinforces the plastics substance) PROVIDED THAT the
embedded sheet or network extends coherently or connectedly
over substantially the whole area of the product; thus the
embedded sheet or network may be a fabric or a series of
rods connected by cross wires. 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. If the
embedded material comprises only a series of unconnected
rods, the product is not classified in this subclass.
This subclass does not cover:
- processes or apparatus used in, or in connection with, the
production or treatment of any product, if the process or
apparatus is fully classifiable in a single other class or
subclass for processes or apparatus, e.g. B05, B29, B44D,
C08J, C09J, C23;
- compositions or preparation or treatment thereof, unless
they are essentially restricted to layered products and
cannot be fully classified in another class without
ignoring this restriction;
- etched metallic pattern on the surface of a printed circuit board.
In this subclass:
- a film formed on a layer by spreading a substance thereon
is not considered to constitute a layer itself if it
serves only as an adhesive or its purpose is merely to
finish a surface of a product;
- groups designating products cover also methods or apparatus
specially adapted for producing such products.
In this subclass, the following terms or expressions are used with the meanings indicated:
- "layer" is a sheet or strip or anything else having a small
thickness relatively to its other dimensions which, together
with at least one other layer, exists in a product, whether
it pre-existed, e.g. as a separate sheet or strip, or was
formed during the production of the layered product. 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. It may
may or may not be in complete contact with the next layer,
e.g. a corrugated layer against a flat layer;
- "layered product" comprises at least two layers secured
together. 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 which 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;
- "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;
- "fibrous layer" means a random assembly of fibres of limited length, e.g. felt, fleece;
the fibres
{
being
}
interengaged or connected, e.g. by adhesive.
In this subclass, - "First place rule" is used in the following groups B32B 9/04 , B32B 11/04 , B32B 13/04 , B32B 15/04 , B32B 19/04 , B32B 21/04 , B32B23/04C - B32B 23/12 , B32B 25/04 , B32B 27/06 , B32B 29/002 . However, when these groups are not characterised by the specific material adjacency to be classified, then, multiple classification is given, e.g. a layered product having a stone layer next to a bituminous layer would be classified in B32B 9/04 and in B32B 11/04 . For a cellulosic plastic layer next to a metal layer or to a wood layer B32B 23/042 or B32B 23/044 , respectively, take precedence (i.e. first rule does not apply). For layered products comprising at least two ceramic layers , products comprising only ceramic layers are classified in group B32B 18/00 and products comprising two ceramics layers and at least one layer of another material are classified in B32B 18/00 and B32B 9/04 .

In groups B32B 37/00
{
, B32B 38/00 , B32B 41/00
}
and B32B 39/00 , the following expressions are used with the meaning indicated:
{
- "lay-up" is condisered to be the action of combining separate layers,one on top of the other, in order to form a half-product for entering the laminating process
}

- "laminating" means the action of combining previously unconnected
{
but possibly laid up
}
layers to become one product whose layers will remain together;
- "partial laminating" occurs when one layer does not fully cover a surface of another layer, whereby the layer with the greater surface area is laminated on only part of its surface;
- "adhesive" means a layer, or part of a layer, applied in any state or in any manner which is incorporated for the purpose of bonding.
