Benefits of technology

[0008] Historically, leather clad panels used in furniture often required the furniture maker to stretch the leather skin to fit the panel. In some applications it was necessary to attach the edges of the skin to the panel's underside prior to attaching the panel to a substrate. In other instances, it was necessary to apply an adhesive to the leather and/or the substrate. Sufficient shrinkage in some instances would-cause the skin to pull away from the underside of the panel, become detached from the substrate, or tear. An advantage of the present laminate is that it provides a leather-surfaced product that can be easily incorporated into furniture and cabinetry. Because the leather decorative layer is an integral part of the decorative laminate, there is no need to fit and/or adhere the skin to the panel or substrate. The present leather decorative laminate attaches to a substrate in the same manner high-pressure laminates are attached to a substrate. If necessary, the present leather decorative laminate can also be trimmed like high-pressure laminates. In short, the present leather decorative laminate provides a product that can reduce or eliminate many of the problems associ

example i

[0029] A single leather decorative laminate 10 is manufactured using a non-continuous press. A build-up consisting of a release sheet, a plurality of core layer 12 sheets, a leather decorative layer 14, and a textured release sheet is made in a superimposed relationship and placed between steel plates. The build-up is then subjected to a pressure of about 1100 psi. Once the predetermined pressure is reached, the press is heated to a predetermined temperature of about 125° C. The press is held at the predetermined pressure and temperature for a heating cycle of about 14 minutes. After the heating cycle is completed, the heat is subsequently removed, but the pressure is maintained for a cooling cycle of about 11 minutes. The pressure is then released and the build-up, which is now a leather decorative laminate 10, is removed. The release sheets are removed and the leather decorative laminate 10 is complete.

example ii

[0030] A leather decorative laminate 10 can be manufactured in a continuous process using a GreCon® continuous high-pressure laminating press, which includes an inlet section, a heating section and a cooling section. The temperature of each section is controlled independently. The total amount of heat imparted to the layers of the build-up is controlled by the temperature of the different sections and the dwell time, which is dependent on the line speed. This continuous process requires that all of the various layers used to manufacture the laminate be fed into the press as continuous webs.

[0031] In the present example, the build-up consists of, from top to bottom, a textured release paper, a pre-dried leather decorative layer 14 and the core layer 12. All layers are fed in a continuous manner into the press at 5 feet / min. The temperature settings of the different press sections are as follows: the inlet section is set at 90° C., the heating section is 135° C., and the cooling sect...

Description

[0001] This application claims the benefit of and priority from U.S. Provisional Patent Application Ser. No. 60 / 441,888, filed 22 Jan. 2003, which is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to decorative laminates in general and, more particularly laminates having a leather or leather-like material as a decorative layer. In addition, the present invention relates to a method for manufacturing the same. [0004] 2. Background Information [0005] Decorative laminates are often used in the construction of cabinetry, furniture, countertops, and other building products. There is considerable consumer demand for decorative laminates in a wide variety of colors, patterns, and textures. Natural leather is another popular material used in the construction of furniture and other applications. Leather is generally perceived as a quality material used in high-end applications. Unfortunately, ...
