As a rule, the technological process with a closed cycle of glued beams and wood panels production begins in the forest. For more information refer to the procurement section. After procurement, we select our materials at the sorting base. Then there is sawing on the sawmill, distillation on the sawmill and sorting of the lumber capital. Next, a sawn timber package is formed to be sent for drying and panel production commences:
1) Drying
The materials are dried to the technical specified level. Uniform, economical and optimal drying is achieved by using drying chambers with automatic control programming, heating, ventilation and humidification functions.
2) Double-sided planer
After the drying, the wood goes on a double-sided planer together with moisture meter.
The moisture meter checks and rejects excessively wet or too dry workpieces.
The humidity of the boards to be further processed is recorded and this data is stored
for a certain period of time so that in the event of defects, it is possible to control
whether the moisture content of the workpieces is within acceptable limits.
3) Secondary sawing
At this stage the beams are sawed again wit multiblade saws for the purpose of getting uniformly correct widths.
The machinery cuts the ends of blanks that have cracks after drying.
4) Defects examination and removal
5) Seperation and sorting
As you can see in the illustration below, the defect parts are sorted separately and tossed out for utilization.
The resulting pieces are carefully sorted by size into groups for further processing.
6) Automatic splicing by length - I
On this lines splicing by length occurs. Furthermore notched spikes are cut at the ends of workpieces for further glueing and splicing
7) Automatic splicing by length - II
Applying the glue on the spikes, 0.1 - 0.3 mm layer.
8) Splicing along the length of defect-free workpieces
The pieces are spliced into lamellae with trimming and edge calibration.
9) Cutting in the lenght of the fused planks
10) Calibration
A four-sided longitudinal milling machine for lamellas performs high-quality processing, first of all, of the upper and lower parts of the workpiece. The spindle speed of the machine is always more than 6.000 rpm.
Longitudinal milling is performed for the purpose of removing the gluing of the glue, the steps between the blanks, the obtaining of precise geometric shapes, and the high purity of the surface of the mallets for further gluing.
11) Applying the glue 0.1 - 0.3 mm
The glue application speed is rather high, 3-150 ml / min and is necesarry because the time between application of the glue and closing of the press should be as small as possible. Ideally, two-component adhesives are used, which are prepared in a kneader and fed to the glueing machine. With a hose, the glue is applied to the moving board at a speed of 60-100 or 80-250 ml / min.
12) Glueing the lamellae together with a hydraulic press
13) Forming dimensions on two lateral surfaces
14) Grinding the surface to attain the perfect surface
15) The finished product!
