Description
- This application is a continuation of application Ser. No. 16/242,436, filed Jan. 8, 2019, now U.S. Pat. No. 10,562,280, which is a continuation of application Ser. No. 15/168,949, filed May 31, 2016, now U.S. Pat. No. 10,173,398, which is a continuation of application Ser. No. 11/716,620, filed Mar. 12, 2007, now U.S. Pat. No. 9,352,486, which is a divisional of application Ser. No. 10/291,757, filed Nov. 12, 2002, now U.S. Pat. No. 7,195,686, all of the disclosures of which are incorporated herein by reference and to which priorities are claimed.
- The present invention is directed toward a method of forming a molded panel having a decorative surface and to the molded panel formed by this method, and, more specifically, toward a method of attaching a decorative layer, such as a wood veneer, a foil, or a non-creped paper, to a substrate in a pressing operation that deforms both the substrate and the decorative layer to produce a panel having a substantially unblemished, finished surface and to the panel formed by this method.
- Many products that have heretofore been manufactured from natural wood are now formed from composite materials that include fibers obtained from wood or non-wood sources. For example, composite panels may be formed by coating a quantity of fibers with a heat curable resin binder, placing a loose mat of these coated fibers in a press, and applying heat and pressure to the mat to reduce its thickness and cure the resin, thereby producing a thin, wood-like board. Such boards may be referred to as “chip board” or “fiber board,” depending on the source of the fibers used in their manufacture, and fiberboards, in turn, may be referred to as softboard, medium density fiberboard (MDF) or hardboard, depending on their densities. These boards are sometimes attached to rectangular frames to form doors, and, when used in this manner, are referred to as “door skins.” When such panels are formed with flat surfaces, they are often referred to as “flush” panels or “flush” door skins; when they are formed with a pattern of depressions, to simulate the appearance of a traditional rail and stile door having panels, for example, they are often referred to as “molded” panels or “molded” door skins.
- While fiberboard panels have a hardness and flexibility similar to sheets of natural wood, their surfaces lack the grain and texture of natural wood, and are therefore generally not suitable for use in applications where a natural wood appearance is desired. Rather, fiberboards generally must be painted or otherwise covered to produce a finished surface. If a fiberboard panel having a wood grain appearance is desired, a layer of covering material must be applied. The layer of covering material may be a natural wood veneer or a paper, foil, or film printed with a wood grain pattern. These layers of covering material are applied in a process separate from the panel forming process, using a membrane press, for example. This additional manufacturing step, however, increases the cost of such products.
- Manufactured wood products, such as the flush door skins mentioned above, may be transformed into non-planar products, such as molded door skins, by placing them into presses and subjecting them to heat and pressure. A process for transforming fiberboard panels is known from U.S. Pat. No. 6,073,419, for example, which patent is hereby incorporated by reference. This patent teaches that resin impregnated crepe paper can be placed into the press while a flush panel is deformed. The creping allows the paper to stretch and deform along with the panel and provides a moisture barrier for use in water resistant applications.
- The heat and pressure required for changing the shape of the flush panel have in the past required the use of a creped paper layer. Non-creped paper tended to tear and wrinkle and produce a surface that required further processing to make it acceptable as a finished surface. Prior art papers used to affect surface properties are generally creped or otherwise textured to allow them to expand with the changing surface area of the flush panel as it deforms. Therefore, they do not produce a uniformly colored surface when the article is removed from the press. Articles formed in this manner must be painted or otherwise covered to hide the wrinkles, stretch marks, and irregularity in the surface color finish.
- It is therefore desirable to produce a decorative, finished surface on a panel of composite material during an operation that forms a flush panel into a molded panel.
- A first aspect of the present invention comprises a method of forming a composite article that involves providing a press having first and second platens, a cellulosic fiber substrate having a first thickness and a layer of material such as wood veneer, foil, or non-creped paper. The layer of material has a thickness less than the thickness of the cellulosic fiber substrate. A bonding material is applied to the cellulosic fiber substrate or to the layer of material, and the layer of material is placed onto the cellulosic fiber substrate so that the bonding material is between the layer of material and the substrate. Next, the substrate and layer of material are placed between the first and second press platens, and at least one of the platens is moved toward the other one to deform the cellulosic fiber substrate and layer of material into a predetermined configuration and bond the layer of material to the cellulosic fiber substrate without cracking or wrinkling the layer of material. Another aspect of the invention is a product made by this method.
- A further aspect of the invention comprises a composite article including a layer of MDF having a first surface and a layer of veneer bonded to the first surface. The first surface is deformed under the application of heat and pressure while in contact with the layer of veneer to form a sharp edge in the veneer layer.
- Another aspect of the invention comprises a method of forming a composite article that involves providing a press and an MDF substrate having first and second sides, and placing a flat sheet of wood veneer on the first side of the MDF substrate, then placing the MDF substrate and wood veneer overlay into the press. The press is closed to simultaneously deform the MDF substrate and wood veneer and bond the wood veneer to the MDF substrate to create a composite article.
- A further aspect of the invention comprises a composite article that includes a deformed sheet of MDF and an uncracked, deformed layer of wood veneer bonded to the deformed sheet of MDF. The uncracked, deformed layer of wood veneer has a moisture content of less than about 2 to 4 percent.
- An additional aspect of the invention is a method of forming a molded panel having a natural wood surface that involves providing a press having first and second platens for deforming sheets of wood composite material and providing a flat sheet of wood veneer. Next, a sheet of wood composite material is heated and moisturized, and a layer of bonding material is applied to either or both of the heated and moisturized sheet of wood composite material and the flat sheet of wood veneer. The flat sheet of wood veneer is placed onto the heated and moisturized sheet of wood composite material, and then the wood composite and veneer are placed into the press between the first and second platens. At least one of the first and second platens is moved toward the other of the first and second platens to deform and bond the MDF and the wood veneer into a finished article. The finished article is removed from the press and then wetted to raise the moisture content of the wood veneer to prevent the veneer from deforming or causing the wood composite panel to bow or cup.
- An additional aspect of the invention comprises a method of forming a composite article having a finished surface that involves providing an MDF substrate having first and second sides and a surface area and laying a sheet of material having the same surface area on the first side. The MDF substrate and sheet of material are placed into a press, and the press is closed to simultaneously deform the MDF substrate and the sheet of material and bond the sheet of material to the MDF without forming wrinkles in the sheet of material.

FIGS. 1-3 illustrate apanel 10 formed from afirst substrate 12, such as medium density fiberboard (MDF), having alower surface 14 and anupper surface 16, a layer of adhesive 18, which may be a thermosetting resin or adhesive, such as a urea-based resin or adhesive, preferably melamine-urea-formaldehyde resin or urea-formaldehyde resin or paper impregnated melamine, for example, and acovering layer 20 having alower surface 22 and anupper surface 24. Coveringlayer 20 may comprise a wood veneer, a foil, or a non-creped paper material which may be plain or bear a printed or other design or image. -
Panel 10 is formed by placingadhesive 18 onsubstrate 12, placing coveringlayer 20 on top of the adhesive 18 and placing the article thus formed into apress 26, illustrated inFIG. 13 , having anupper die 28 attached to anupper platen 30 and alower mold cavity 32 attached to alower platen 34. To makesubstrate 12 easier to deform, it is preferably heated and moistened before thecovering layer 20 is attached in the manner taught in WO 98/48992, which is hereby incorporated by reference. One of theplatens press 26, and heat and pressure are applied to the article in thepress 26 until it assumes the profile illustrated inFIG. 3 . Pressure is applied cyclically in the manner taught in WO/9848992, at a constant rate, or at a constantly increasing rate. Thepress 26 may be vented during the pressing operation to release steam and other volatile materials generated during the pressing operation. The heat of thepress 26 both keeps thesubstrate 12 at a temperature at which it is deformable and cures adhesive 18 to bond the coveringlayer 20 to thesubstrate 12. - The heated and moistened
substrate 12 enters thepress 26 with a moisture content of about 10-12 percent by weight and exits with a total moisture content of about 5 to 7 percent by weight. When coveringlayer 20 is a wood veneer, it cannot be preheated and moistened in the same manner as thesubstrate 12 without warping or bowing the veneer. However, if the veneer is placed into thepress 26 without pre-moistening, it emerges at a very low moisture level, less than 2-4 percent, for example, and soon deforms, ruining the surface appearance of thepanel 10. Therefore, it has been found necessary to moisturize thepanel 10 when it is removed from thepress 26, to increase the moisture content of the veneer to prevent the veneer from deforming. This may be done, for example, by spraying water on thepanel 10. Surprisingly, it has been found that this moisturizing step prevents the veneer from deforming and does not adversely affect the properties of thepanel 10. Thepanel 10, after moistening will have a moisture content of about 7 percent. When coveringlayer 20 is a foil or a non-creped paper, the post-pressing moisturizing step may be omitted. - Preferred veneers include those comprising cherry or mahogany, although many different woods provide satisfactory results. Furthermore the thickness of the veneer is preferably in the 0.3 to 0.9 mm range, most preferably about 0.6 mm. A
preferred adhesive 18 is a melamine impregnated sheet of paper. - Because the
substrate 12 and coveringlayer 20 are deformed in the same step by the same molds, thelower surface 22 of thecovering layer 20 will correspond almost exactly to theupper layer 16 of coveringlayer 20. This allows the adhesive 18 to securely bond these twolayers substrate 12 supports the somewhatfragile covering layer 20 over its entire surface. Moreover, when coveringlayer 20 is a layer of wood veneer, the heat of thepress 26, and the moisture released in thepress 26 during the pressing operation, help mold the outside surface of coveringlayer 20 and form a sharper edge than would have been possible had a wood veneer covering layer been attached to a previously molded substrate. This simultaneous deformation produces a panel having better fidelity and sharper definition that was typically obtained from prior art processes. -
Panel 10 formed by this process includes anupper surface 36 having first and secondplanar side portions planar portion 42 therebetween, as shown inFIG. 1 . A firstangled wall 44 extends between firstplanar side portion 38 andcentral portion 42 and connects to firstplanar side portion 38 at afirst corner 45 and tocentral portion 42 at asecond corner 46. The distance between the plane of the first andsecond side portions planar portion 42 is preferably about 6-9 mm. It is believed that deforming thepanel 10 in one direction only, namely in a direction parallel to the length ofcorners covering layer 20 will deform, wrinkle or crack. When coveringlayer 20 is a wood veneer, the veneer should be applied to thesubstrate 12 with its grain direction aligned with the direction of deformation, that is aligned withcorners - When covering
layer 20 is a non-creped paper or foil, it may include a printed pattern, such as wood grain, inlaid tiles, or a detailed graphic or artistic image. Because thecovering layer 20 is not creped, the product leaves the press with a finished surface, and any image on that surface is not torn, wrinkled, or distorted. -
FIGS. 4-6 illustrate apanel 50 according to a second embodiment of the present invention. Elements common to both embodiments are identified with the same reference numerals.Panel 50 includes asubstrate 12 and acovering layer 51 comprising a wood veneer having apaper backing 52. Thispaper backing 52 is present on many commercially available veneers. Thepaper backing 52 helps maintain the integrity of the veneer when pressed and reduces the likelihood that the veneer will crack during pressing. The use ofpaper backing 52 may allow for greater offsets between the plane ofside portions panel 50. Furthermore, thepaper backing 52 may incorporate a heat activated bonding agent that will bond the coveringlayer 51 to thesubstrate 12 during pressing, eliminating the need for a separate adhesive applied to the substrate. Alternately, a separate bonding agent, such as a liquid adhesive or a resin impregnated paper sheet, could be used to join the paper-backedcovering layer 51 tosubstrate 12.Panel 50 is formed by pressing thecovering layer 51 withpaper backing 52 andsubstrate 12 in apress 26 as discussed above. Veneers having backings in the form of meshes or scrims or fabrics or layers of fusible material are also commercially available and may be used in the present invention as well. -
FIGS. 7-9 depict apanel 53 according to third embodiment of the present invention. Elements common to previous embodiments are identified with the same reference numerals. In this embodiment, acovering layer 54 comprising a plurality ofstrips 56 of wood veneer secured together by apaper backing 58 is used. Thestrips 56 are preferably about six inches wide. The use of joined-together strips 56 may provide acovering layer 54 having improved flexibility in the direction of the length ofstrips 56 and allow thecovering layer 54 to flex when pressed with less chance of cracking or warping. -
FIGS. 10-12 depict a fourth embodiment of the present invention wherein apanel 60 includes a depressedcentral portion 62 surrounded by first and secondplanar side portions 64, 66 aplaner top portion 68 and a planarlower portion 70. First and second slopedwalls 72 connect firstplanar side portion 64 tocentral portion 62 while third and fourth slopedwalls 74 connect thetop portion 68 andbottom portion 70 to the central portion. The slope of the third and fourth slopedwalls 74 is less than the slope of the first and second slopedwalls 72 to minimize cracking when coveringlayer 20 is a wood veneer and to minimize wrinkling and/or tearing when coveringlayer 20 is a foil or paper. In addition, thetransition areas 76 between the first and second slopedwalls 72 and the third and fourth slopedwalls 74 are smooth and gradual, as seen inFIG. 10 , which further reduces the cracking or wrinkling that would likely occur if these slopedwalls - The present invention has been described above in terms of several preferred embodiments. However, it should be understood that may obvious modifications and additions to these embodiments will become apparent to those skilled in the art after reading this disclosure. For example, while the invention has been described as primarily useful in connection with fiberboard, it could also be practiced on other materials such as fiberglass. Moreover, the panels formed by this method can vary in shape and configuration and might be useful, for example, as baseboard. It is intended that all such obvious modifications and additions form a part of this invention to the extent that they are included within the scope of the several claims appended hereto.
