Pty Limited, 14 Henry Street, Picton, New South Wales, 2571, Australia Michael Lindsay Boyd, Keith Robert Wells Spruson Ferguson St Martins Tower Level 31 Market Street Sydney NSW 2000 (CCN 3710000177) Method and apparatus to apply a cushion underlay to carpet Associated Provisional Application Details: [33] Country: [31] Appl'n No(s): [32] Application Date: 2007904900 10 Sep 2007 The following statement is a full description of this invention, including the best method of performing it known to me/us: 5845c(1263333_1) 00 METHOD AND APPARATUS TO APPLY A CUSHION UNDERLAY TO CARPET
;Z
Technical Field The present invention relates to the construction of a laminated floor covering including carpet and underlay, and a method and apparatus for the manufacture thereof.
Background of the Invention SThe construction of synthetic carpet can consist of a Nylon (Registered Trade 00 0Mark) yarn tufted into a polyester or polypropylene sheet backing material. The "under" r side of the backing material through which the yam projects is coated with Latex 1o (Registered Trade Mark) to aid in the securing of a layer of polyvinylchloride (PVC) to the polyester or polypropylene sheet backing material. The Latex also aids in holding the yarn fixed to the backing material during processing.
In the manufacture of PVC carpet tiles, typically the abovementioned PVC layer is applied in a continuous fashion and is essentially a laminated construction consisting of Is an uncured PVC paste layer, a fibreglass layer, and a further uncured PVC paste layer.
The above laminated construction is supported on a Teflon (Registered Trade Mark) coated fibreglass belt that runs over heating elements which heats the PVC paste layers to a curing temperature of about 150'C, thus bonding the tufted yarn to the backing material.
The total laminated construction is then cooled to about 105'C to allow removal of the construction from the Teflon belt.
The above laminated construction is then passed through a heater and raised to about 120'C prior to being engaged by an embossing roller that embosses the PVC backing.
A disadvantage of the above discussed laminated construction is that the backing provides little cushioning.
In an alternative construction of the above carpet tiles, the PVC layer is replaced with a bitumen layer. This construction has the disadvantage that it is not suitable for recycling. A further disadvantage is that any cushion layer applied thereto is prone to "peeling".
1262130 l:hxa 00 Object of the Invention It is the object of the present invention to overcome or substantially ameliorate
;Z
the above disadvantage.

1262130 l:hxa 00 Brief Description of the Drawings SA preferred form of the present invention will now be described by way of example with reference to the accompanying drawings wherein: Figure 1 is a schematic sectioned side elevation of a portion of a carpet tile; and Figure 2 is a schematic side elevation of a machine to make carpet lengths from N, which carpet tiles can be formed.
N Detailed Description of the Preferred Embodiments 00 In Figure 1 of the accompanying drawings there is schematically depicted a portion of a carpet tile 10 incorporating a cushion layer. The carpet tile 10 includes a yarn fibre (pile) layer 11 that would be typically a Nylon (Registered Trade Mark) yam tufted into a polyester or polypropylene sheet backing material. The "under" side of the sheet backing material with the yam projecting therethrough is coated with Latex (Registered Trade Mark). The Latex aids in securing the yam to the sheet backing material. The layer 11 is fixed to a backing layer 12 formed of plastics material such as polyvinylchloride (PVC) or polyurethane. The backing layer 12 includes a fibreglass layer located between two PVC layers. The fibres 13 of the layer 11 are partly embedded in the layer 12 so that the layer 11 is mechanically bonded to the layer 12.
Fixed to the layer 12 is a cushion layer 14 so that the backing layer 12 is located between the cushion layer 14 and the fibre layer 11. The cushion layer 14 includes a foam layer 15 of a foam plastic or synthetic rubber material, and a scrim 16. The scrim 16 is a sheet material that may contain a mesh, and would include polyester fibres. The scrim 16 is secured to the layer 15 by means of an adhesive.
Fibres of the scrim 16 are at least partly embedded in the layer 12 so that the cushion layer 14 is mechanically bonded to the layer.
In Figure 2 there is schematically depicted an apparatus 20 to manufacture a floor covering such as the carpet tile 10. The machine 10 includes a frame 21 that has a plurality of rollers and belts that support a first laminated layer 22 for movement in the direction of the arrow 23. The layer 22 consists of the layer 11 with the layer 12 fixed thereto. The layer 22 is delivered to a heater 23 that has a heating chamber at a temperature of 140'C to 170°C, preferably 150 0 C to 160 0 C (most preferably about 150'C) so that the layer 22 when passing therethrough is heated. In particular the layer 12 is heated so as to be plastically deformable.
