    Abstract: The invention relates to a method for manufacturing a stabilized veneer without a carrier board, a stabilized veneer and a veneered board. In order to provide a method for manufacturing a veneer as well as a veneer, wherein the veneer is particularly stable and in particular has a particularly high mechanical stability against compressive loads, can be easily and safely processed as an intermediate product, has a particularly low veneer thickness and is thus particularly inexpensive to manufacture and still has a good real wood look and real wood haptic, it is provided that the method for manufacturing a stabilized and/or a rollable veneer without a carrier board has as method steps first a provision of a stabilization sheet, followed by a coating on one side, in particular a top side, of the stabilization sheet with a condensation resin, and subsequently a pressing of the stabilization sheet and the veneer layer to configure a stabilization layer by means of the condensation resin, wherein the condensation resin is at least partially pressed from the stabilization sheet into the veneer layer during pressing and leads there to a solidification or mechanical stabilization of the veneer.

    Abstract: The present invention relates to a method for determining the quantitative ratio of melamine-formaldehyde resin and urea-formaldehyde resin in at least one paper layer impregnated with a mixture of these resins, wherein the impregnation is carried out in a plant for impregnating at least one paper layer passing through the plant, comprising the steps Impregnating of several paper layers with resin mixtures, each with different quantitatively defined ratios of melamine-formaldehyde resin and urea-formaldehyde resin as reference samples; Recording of at least one NIR spectrum of each of the reference samples using at least one NIR measuring head in a wavelength range between 500 nm and 2500 nm, preferably between 700 nm and 2000 nm, particularly preferably between 900 nm and 1700 nm, and especially advantageously between 1450 nm and 1550 nm; Correlating the different quantitative ratios of melamine-formaldehyde resin and urea-formaldehyde resin in the reference samples to the recorded NIR spectra of said reference samples; and Establishing a calibration model for the correlation between the spectral data of the NIR spectra and the associated quantitative ratios of melamine-formaldehyde resin and urea-formaldehyde resin of the reference samples by means of multivariate data analysis; Impregnating at least one paper layer with a resin mixture of melamine-formaldehyde resin and urea-formaldehyde resin; Recording at least one NIR spectrum of the impregnated paper layer using the at least one NIR measuring head in a wavelength range between 500 nm and 2500 nm, preferably between 700 nm and 2000 nm, in particular preferably between 900 nm and 1700 nm and especially advantageously between 1450 nm and 1550 nm; and Determining the quantitative ratio of melamine-formaldehyde resin and urea-formaldehyde resin in the impregnated paper layer by comparing the NIR spectrum recorded for the impregnated paper layer with the calibration model created.

    Abstract: The invention relates to a device for depositing veneers on a carrier board. In order to create a device and a method by which veneers can be applied to a carrier board particularly easily, quickly and precisely, provided in the region of an upper end of a transporting device is a veneer magazine, with at least two compartments which are designed to store and supply veneer strips, and with means for transferring the veneer strips from the compartments to the transporting device, wherein the transporting device extends from an upper end obliquely downwards in the direction of a lower end in the region of a transporting plane for the carrier board and is designed to transport at least two individual adjacent veneer strips from the upper end to the lower end and to deposit them on the carrier board.
