DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a panel and to a method for producing the panel having first and second opposite major surfaces, the first major surface simulating a framed-up panel of the type comprising an infill panel and a pair of spaced apart stiles joined by a pair of spaced apart rails which together extend around the infill panel.
Wood panels of the type which are referred to as framed-up panels are used extensively, for example, as apartment doors, doors for cabinets, cupboards, panels for coffins, panelling for walls, ceilings and the like. In general, such panels comprise a frame formed by spaced apart vertical stiles joined by spaced apart horizontal rails which together surround an infill panel or a plurality of infill panels. Traditionally, the stiles, rails and infill panel have been constructed separately from hardwood, such as for example, mahogany, oak and the like and then assembled. However, due to the relatively high cost of such woods, such panels are commonly constructed wholly or partly from a substrate of low grade wood, wood particles or chips laminated with a veneer sheet. For example, the infill panel may comprise a substrate of a low grade wood, for example chipboard, fibre board of high, medium or low density, or other suitable substrate laminated with a veneer sheet of hardwood, softwood, synthetic foil or the like. The stiles and rails may likewise be constructed from a similar or different type of substrate laminated with a similar or different veneer sheet, or may be of hardwood. While such framed-up panels result in a reduction in the material cost, nonetheless the labour cost required in assembling such panels is relatively high.
It is known to produce a framed-up panel using a single sheet of low grade wood as a substrate laminated with a veneer sheet of hardwood, softwood or synthetic foil. Typically the substrate is formed from a sheet of chipboard, medium density fibre board or the like. One surface of the substrate is machined to form simulated stiles, rails and an infill panel. If desired the infill panel may simulate a raised infill panel. A single veneer sheet is laminated to the formed surface by compression moulding the veneer sheet to substrate to follow the contours of the formed surface. Alternatively, in cases where the depth of the surface of the infill panel below the surface of the stiles and rails is relatively shallow, the stiles, rails and infill panel may be formed by embossing during lamination of the veneer sheet to the substrate. In such cases, machining of the substrate prior to lamination with the veneer sheet is avoided. Framed-up panels formed in this way have been of only limited success, irrespective of whether a surface of the substrate has been machined to form the stiles, rails and infill panel prior to lamination of the veneer sheet, or not. Such panels suffer from two major disadvantages. Firstly, where the veneer sheet is of timber or other sheet material having a grain pattern, since a single veneer sheet is laminated to the substrate, the grain of the veneer sheet runs in a single direction only over the entire panel. Accordingly, where the grain runs parallel to the stiles, the grain must run transversely of the rails or vice versa. This is clearly undesirable, since the panel so formed lacks a look of authenticity. A second major disadvantage of such panels is that the maximum depth between the surface of the infill panel and the surface of the stiles and rails is limited. Wood veneer sheets while they are relatively malleable and stretchable in one direction, namely, in a direction transversely of the grain, their malleability and stretchability is relatively poor in a direction parallel to the grain. This seriously limits the depth to which the surface of the infill panel can be formed relative to the surface of the stiles and rails. Where the grain of the wood veneer runs transversely across the rails, if the depth of the surface of the infill panel below the surface of the rails is too great, in other words, if the steps betwe
