Procedures and devices for the production of endless timber by means of wedge zinc coating to plywood bearers and other timber products

摘要

Wide laminated wooden beams require wide individual boards, which the forestry industry is not always able to provide owing to the intensive exploitation. Boards are glued to form a carpet and the latter is cut to the desired width. This production is expensive. Wide boards must be slotted before the gluing, because of the internal stress. A method is sought which satisfies both national- and forest-economic interests and makes it possible to produce wide laminated wooden beams from narrow boards, or, e.g. as is possible in the steel industry, to produce more load-bearing sections from a small amount of raw material by using UTI and hollow sections, the installations used also being used for normal production. This is achieved in that the gluing of lengthwise joints of a plurality of narrow boards for a given width of the laminated wooden beam in separate webs is automatically carried out and the boards are introduced, via the glue application, into the laminated wood press, glued and pressed, and [lacuna] is capable of producing corresponding sections and of transporting these for further processing or final processing. At the same time, this installation is capable of achieving very high outputs and of making conventional production considerably more economical. IMAGE
