SI20258A - Process of manufacture of hollow wooden articles - Google Patents

Abstract

A process of manufacture of hollow wooden articles, first of all furniture elements such as table legs, binding laths as well as various decoration boxes, such as packaging boxes e.g. for decoration pieces or presents, is enabling a cheaper and faster manufacture of articles of the same quality as those made of massive wood. The process according to the invention comprises several phases. First phase: manufacture of a flat semifinished article (1) consisting of two plates (2, 3) connected by laths (4), the spacing of their longitudinal axes being approximately equal to the width of the finished article (5), and with their ends closed by two transverse laths (6); second phase: cutting of the semifinished article (1) within the lath area (4) into finished articles (5); third phase: adjustment of the finished products (5) to the required length by cutting; fourth phase: fitting the side or cut planes of the dimensionally determined finished article (5) with a final material, preferentially veneer; fifth phase: surface finishing of the end article.

The process of making hollow wooden objects

The subject of the invention

The object of the invention is a method of making hollow wooden objects, especially furniture elements such as table legs, laths, and in addition, various decorative boxes such as packaging, e.g. for ornaments and gifts.

A technical problem

A technical problem solved by the invention is how to design such a process for the manufacture of hollow objects made of wood, in particular such as are mentioned in the first paragraph of this description, to give the final appearance of the product as if made from solid wood, making the process suitable for large-scale production in technological as well as in price terms.

The prior art

No such procedure is known. For wooden furniture legs of tables, laths, etc. so far, as a rule, they have only used an array to achieve the appearance of natural wood.

The production of such solid wood products first requires a dedicated cut of the highest quality logs to utilize the wood for the already known product dimension

26889 / VI-99 / D20-Vr e.g. foot tables. Namely, we cannot afford to cut non-standard dimensions into stock, because there would be too much waste and cash, which would lead to unprofitable production. In order to shorten the already long production cycle, the drying process is accelerated, which in turn leads to cracks, stains, discoloration, and bending of the products. Each of the running anomalies leads to increased droppings.

In addition, the use of solid wood for larger objects is expected to result in additional ejection due to cramps and other defects in the wood.

From the above, there is a great need for a new tonnesmaking process that will ensure the production of equivalent products in terms of strength as well as in aesthetic and price terms.

The solution to a technical problem

The described technical problem is solved by the method according to the invention by making a semi-finished product of two, preferably veneered panels, which are connected to each other on the backs by spaced laths, this sandwich being closed at both ends of the laths with transverse laths. The spacing between parallel running strips is in line with the width or thickness and the length of these strips with the length of the finished product, e.g. legs at the table.

The sandwich plate is then cut along the middle of parallel strips and, if necessary, transversely to the intended dimension of finished products. As mentioned, the semi-finished panels are already veneered or otherwise coated, so that after the cutting, the two opposite faces of the finished product are already finished. The remaining two opposite surfaces of the final product are coated, e.g. we veneer separately on each finished product. After surface treatment, e.g. painting, etc., the product is finished.

26889 / VI-99 / D20-Vr

Given the nature of the finished product, the sandwich plate may not necessarily be closed at both ends. We can also carry out at one end an open product that represents a container, a box, etc.

However, if we assume that other items will be installed on the finished product, e.g. on the table leg a furniture wheel or a screw connection element for connection to the table board, the end element, which closes the parallel running strips, can be made with a suitable thickness that allows the mounting of these connecting elements in a threaded manner or the use of longer wood screws.

The process according to the invention achieves significantly faster batch production of hollow wooden objects by using massive, smaller pieces, including already scrapped pieces. There is no need to worry about stockpiling specialty solid wood that loads cash. Because the surface is veneered, the internal massif can be of any kind of wood, which only has to be solid and technological, not aesthetic. Consumption of wood is significantly reduced. In addition to the massif, other materials can also be used for interior slats: chipboard, hardboard, plywood, etc. For coating, in addition to veneer, foils of other plastic materials, paper, etc.

The essence of the invention will be explained in more detail below with a description of an embodiment and the accompanying drawing, in which FIG. 1 is a perspective view of a semi-finished semi-finished product, FIG. 2 is a perspective view of a semi-finished product in a cutting, FIG. 3 perspective view of the final product in the coating.

The process of making hollow wooden objects comprises several stages. First, a flattened semi-finished product 1 is made, consisting of two plates 2, 3, which are interconnected at

26889 / VI-99 / D20-Vr backs with approximately parallel extending laths 4, the spacing of the longitudinal axes being approximately equal to the width of the individual finished product 5, while the thickness of the semi-finished product 1 is equal to the thickness of the finished product 5. The panels 2, 3 are at cheeks already made with the finishing material as intended on the finished product

5. Preferably, it is veneer. If necessary, at least one side of the ends of the lath 4 is closed by a transverse lath 6 whose width corresponds to the intended eventual further installation of other assemblies or to any connection of the finished product 5 with other furniture assemblies, such as: furniture rollers, screw ties, etc. not shown on pictures.

This is followed by cutting the semi-finished product 1 in the area of the laths 4 along the line 7 into the finished products 5. If necessary, the finished products 5 can then be reduced to the required length.

The dimensioned finished product 5 is then coated on the remaining two lateral surfaces or on the cutting surfaces with the final material 8, usually veneer. The following is the surface treatment of the finished product: grinding, painting, varnishing, etc.

The dimensions of flat semi-finished and finished products are only conditioned by the technological capacity of the hardware. All the individual cutting, gluing, surface treatment processes described are known per se.

The described procedure can be further upgraded by additional procedures e.g. milling, angled, etc. to give additional design features that do not alter the essence of the invention.
