Abstract

Furniture blank with at least one printed photo motif on at least one of its outer surfaces, wherein the furniture blank has a veneer body which has a multilayered layer structure and the outer veneer layer of the veneer body is printed, characterized in that the furniture blank has at least one area, which is a non-planar Has contour.

Description

The invention relates to a furniture blank, d. H. a semifinished product or intermediate product or a part which is processable or becomes part of a piece of furniture, such as a wood trim part, seating or table.

For some time now photomotives, d. H. especially using digital printing printed flat veneer panels known.

These can be used for example for the personalization of furniture and other commodities made of molded plywood or made of molded plywood.

So far, such photo motifs are applied to flat or planar veneer sheets, which has long been a need for non-planar or non-planar veneer blanks, which can serve as a seat of seating and the like, for example.

From the DE 20 2007 058 034 B4 It is known to cover a base material, in particular a veneer, a wood trim part, with a film which is provided with a pattern. The disadvantage here is in particular that the use of the film requires an additional processing step and regularly leads to increased production costs.

From the DE 10 2004 051 828 B4 It is also known to provide a base material of a wood trim with a pattern. Here, the base material is first photographed and then bleached. Thereafter, the bleached surface of the base material is printed with a pattern corresponding to an overlay of the captured image and a desired image. The disadvantage here is that the resulting pattern is always dependent on the visual appearance and / or the surface structure of the base material. Individually designed wooden trim parts can not be realized thereby. In addition, the printing of the base material is made difficult by the bleaching, especially because this can roughen or destroy the surface of the base material.

From the automotive industry or from the DE 10 2014 011 138 A1 a method for producing a wood trim is known.

In this method for producing a wood trim part with a base material which is a wood veneer, the base material is always pretreated bleach-free and subsequently applied to the base material ink. On the base material, a predetermined pattern is imaged by the ink application.

The necessary pretreatment is a process step which requires additional demand.

The object of the invention is to provide a non-planar or non-planar furniture blank, in particular a veneer blank, which has the requisite required stability and which has an imprinted photo motif on at least one of its surfaces. This furniture blank is to be obtainable in particular from a pre-press by printing using known digital printing methods, without previously a previously usual pretreatment is required.

The object of the invention is solved by the features of claim 1.

The dependent claims 2 to 4 contain advantageous embodiments of the invention without limiting this.

Further features, properties and advantages of the present invention will become apparent from the following description of exemplary embodiments without limiting this.

The furniture blank can be obtained, for example, by the following steps:
The production of a pre-compact takes place, for example, from two veneer plates made of beech, alternatively also from birch or maple or other veneer-suitable types of wood, which are glued in opposite directions to one another in their usual manner.

For example, the two veneer plates each have a material thickness of 1.2 mm.

The gluing takes place after in the DIN 68705 fixed gluing quality IF20.

For the covering veneer of the pre-compact, which at the end forms the visible side of the furniture or at least a part of a piece of furniture, a high quality veneer of grade A, acc. DIN 68707 used.

Subsequently, applying the pre-compact on a suitable support plate by screwing with countersunk screws, so that then the outer surface of the pre-press is flat and can be printed in the usual manner. This ensures a high print quality in a simple manner.

Alternatively to the use of the rigid pre-compact and so-called. Fleece-laminated veneers are applicable.

In addition, an application of marks for the subsequent printing, in particular a centering and / or the maximum / minimum pressure surface, take place.

The step of printing begins with the selection of the photo motive in digital format (content / legal examination).

It is advisable to carry out a technical examination of the photo file according to size and resolution (for example at least 72 dpi, at least 2 MB size).

In addition, a formatting of the photo subject depending on the later end product is regularly useful.

The actual printing of the prepared pre-press using the following possible digital printing methods:
UV direct printing, tampon printing or offset printing.

After printing, the detachment of the pre-compacting takes place from the carrier plate.

Subsequently, the shaping further processing of the plan pre-compact takes place in the usual way to a furniture blank, in particular to a non-planar or non-planned furniture blank.

In preparation for the shaping further processing, the glue layers are applied (analogously to production of pre-compact, gluing quality IF20) DIN 68705 ) on all veneer layers by gluing device or alternatively by manual application.

This is followed by manual folding of the individual veneer layers into a block and fixation of this block. Subsequently, the insertion into the prepared, d. H. in particular equipped with the corresponding pressing tool pressing device and usual deformation with appropriate heat.

• A. Schichtaufbau bei Verwendung des Möbelrohlings als sichtbares Teil und dabei mit sichtbarer Vorder- und Rückseite für Möbelstücke:
• – einen ersten Vorpressling, bestehend aus einer Deckfurnierschicht (Güteklasse A) und einer Furnierschicht (Güteklasse B),
• – fünf bis sieben Furnierträgerschichten (Güteklasse C), sowie
• – einen zweiten Vorpressling, bestehend aus einer Furnierschicht (Güteklasse B) und einer Deckfurnierschicht (Güteklasse A).

For the layer structure of the furniture blank, the two options described below are fundamentally relevant in the context of this invention.

• A. Layer construction when using the furniture blank as a visible part and with visible front and back for furniture:
• A first pre-compact consisting of a top veneer layer (grade A) and a veneer layer (grade B),
• - five to seven veneer layers (grade C), as well as
• - A second pre-compact, consisting of a veneer layer (grade B) and a top veneer layer (grade A).

• B. Schichtaufbau bei Verwendung des Möbelrohlings als sichtbares Teil und dabei mit sichtbarer Vorder- oder Rückseite für Möbelstücke:
• – einen Vorpressling, bestehend aus Deckfurnierschicht und einer Furnierschicht (Güteklasse B),
• – fünf bis sieben Furnierträgerschichten (Güteklasse C), sowie
• – einer Furnierschicht (Güteklasse B).

In a two-sided personalization of the furniture, ie printing on the front and back, the printed layers of the pre-presses respectively form the top and bottom layers of the veneer block.

• B. Layer structure when using the furniture blank as a visible part and with visible front or back for furniture:
• - a pre-compact, consisting of a veneer layer and a veneer layer (grade B),
• - five to seven veneer layers (grade C), as well as
• - a veneer layer (grade B).

The furniture blank produced by the shaping further processing can be subjected to further processing steps, such as:

contouring

• Machining in a CNC milling machine for the final contouring of the furniture blank or veneer block.
• Preparation of mounting surfaces and holes; Gluing of fastening sleeves
• Grinding of the milling edges.

paintwork

• Seal the finished veneer block with a suitable low-pollutant water-based protective lacquer.
• Smoothing and polishing of the surfaces.
