Description

CLADDING BOARD The present invention relates to cladding boards.
In particular, it relates to cladding boards in the form of laminates.
Cladding boards for decorative use inside buildings are well known. Frequently, the boards are formed from a series of wooden planks fitted together in a side-by-side arrangement, by means of complementary tongue and grooves running along respective longitudinal edges of the planks. Such cladding is commonly known as tongue and groove boarding. Whilst being popular because it gives a pleasing decorative and natural wood appearance, it is nevertheless expensive, difficult and time consuming to erect. Alternatively, plain board cladding is sometimes used, but this does not give the pleasing decorative appearance of tongue and groove boarding.
The present invention provides a new type of cladding board which may overcome these problems.
The present invention is based on the idea that a board may be shaped to resemble the appearance of tongue and groove planks. The board may be formed as a laminate, in which case the outer layer may be shaped, with the inner layer(s) of a less expensive material.
Thus, the present invention may provide a cladding board which comprises a board with a series of parallel grooves such that pairs of grooves define ribs and the board simulates the appearance of tongue and groove boarding.
The board may be medium density fibre board.
The present invention also provides a cladding board which comprises a laminate of at least two layers of different materials, one of the layers being of natural wood, which layer of natural wood has the parallel grooves defining ribs and wherein the grooves forming the parallel ribs extend substantially or wholly through the wood layer, but do not extend substantially into any other layer.
The cladding board may comprise a laminate of three or more layers. Where the cladding board has three layers, both outer layers may be of natural wood and both layers have the series of parallel grooves defining the ribs. Alternatively, where there are three layers, one of the outer layers may be plain.
The grooves defining the ribs may be spaced at any distance apart. They may also be spaced a distance apart which corresponds to the width of the planks conventionally used in tongue and groove boarding, suitably 15cms.
The board may include one or more layers of fire resistant and/or insulating material. The thickness of the grooved layers may be 2.5mm, so that they are sufficiently thick for the decorative pattern of grooves to be cut into them, without the grooves extending substantially into other layers.
The present invention also provides a method of forming cladding boards according to the present invention, which method comprises forming the board and grooving the board to define the ribs such that the board simulates the appearance of tongue and groove boarding.
The method may also comprise forming the board as a laminate with at least one layer of natural wood, grooving the natural wood layer to define the parallel ribs, wherein the grooves formed extend substantially or wholly through the wood layer, but do not extend substantially into any other layer.
The grooves may be made by passing the boards below a revolving drum which has a plurality of profiled blades extending from its outer surface, in a manner such that the natural wood layer only, has the parallel series of ribs grooved into it.
The cutting edges of the profiled blades and/or the spacing of the profiled blades on the drum surface may be varied to alter the grooves and therefore the ribbed pattern of the cladding board.
The present invention also provides a machine for forming a cladding board according to the present invention, which machine comprises a cylindrical drum rotatable about its central longitudinal axis, which has a plurality of profiled blades which extend from its outer cylindrical surface, wherein the blades are dimensioned to cut grooves in a board, the appearance of which grooves in the board simulates the appearance of the join between adjacent planks in tongue and groove boarding.
Embodiments of the invention will now be described by way of example and with reference to the drawings, in which: Figure 1 is an elevational view of cladding board according to the invention; Figure 2 is a sectional plan view of one embodiment of the cladding board; Figure 3 is a sectional plan view of another embodiment of the cladding board; and Figure 4 is a perspective view of revolving drum assembly (with cutting blades exaggerated in scale) for forming cladding boards according to the present invention.
Referring to the drawings the cladding boards 10 as shown are formed as laminates of three layers wherein two outer layers, 12 and 14 sandwich an inner layer 16. The inner layer 16 is suitably made of composite material, for example medium density fibre board or any other boards formed from wooden fibres or chips compressed together and formed into blocks (which may then be cut into sheets) with a resin. Such a material is readily available and inexpensive.
In the embodiment shown in Figure 2 both outer layers 12 and 14 are formed from natural wood of a high quality. These natural wood layers are suitably 2.8mm thick. These outer layers 12 and 14 are grooved to create a series of parallel ribs 18, to simulate to the appearance of the tongue and groove joints that are present in tongue and groove boarding. Each rib 18 is formed from two parallel gooves 20 and 22, one of which is a shallow part v-shaped groove 20 whilst the other groove 22 is deeper. This deeper groove 22 cuts substantially or wholly through the outer layers 12 and 14, but not substantially into the inner layer 16. The rib 18 between the two grooves 20 and 22 is rounded and does not rise to the level of the top of the layers 12, 14.
In the embodiment shown in Figure 3 only one of the outer layers 12 and 14' is profiled with the parallel ribs. In this case it is not necessary to make the plain layer 14' may not be made of high quality wood. The plain layer 14' may also be formed from several pieces of material arranged side by side. The embodiment shown in Figure 3 is useful, where the board is used in situations where only one surface of the board will be visible. The plain layer 14' gives the board stability and helps prevent warping and moisture damage. The embodiment shown in Figure 4 is useful where the board is used in situations where both the surfaces 12 and 14 will be visible.
The outer layers 12 and 14 may comprise large sheets of veneer or suitably, adjacent strips 40, 42 and 44 of veneer. These strips 40, 42 and 44 are attached to the inner layer 16. They are spaced a small distance apart, so that the deep groove 22 is formed between adjacent strips. The veneer strips when attached will have straight sided edges. The edges of these strips are then grooved (as described hereafter) to create the appearance of tongue and groove boarding. Each strip of veneer used is slash sawn and not peeled as normally done in the art.
In an alternative embodiment (not shown) the cladding boards 10 may comprise a single layer of material, suitably a composite material such as a medium density fibre board lOmm thick. This single layer board will then be profiled by forming the parallel grooves to define the parallel ribs. Such a board may be used where it is intended to be painted and only the ribbed effect and not the natural wood finish of tongue and groove boarding is desired.
As shown in Figure 4, the cladding boards of the invention are formed by a use of a machine which comprises a generally cylindrical drum 28 rotatable about an axis 30 parallel to the top surface of a board 10 being fed into the machine.
The cylindrical outer surface 32 of the drum 28 is provided with a plurality of profiled blades 34 (only three of which, greatly magnified are shown in the Figure).
A board 10 to be ribbed or to have additional ribs cut into an outer layer 12, 14 is fed lengthways into the machine, the drum being rotated so as to cut ribs into that surface of the board adjacent the drum 28 whilst the board is being passed below it. The cutting edges 36 of the profiled blades are designed so that they can cut the rib pattern of grooves 20, 22.
The cutting of the grooves may be undertaken during several passes of the board beneath the drum 28 the spacing between the board and the axis of the drum being reduced with each passage of the board.
The cutting edges 36 of the profiled blades 34 and/or the spacing between adjacent profile blades 34 may be altered to change the decorative ribbed pattern of the board.
They can be manufactured in large sheets such as 120cm x 240cm which makes them easier to fix over large areas than conventional tongue and groove boarding.
Since it provides a natural wood finish it is also more attractive than the grooved laminates known to date.
