Sawmills form part of the primary industry that transforms timber into semi-finished wood, mainly for use in carpentry, joinery, construction and elsewhere. Variable-speed drives and starters operate the electric motors used in each phase of the process.
Despite its great complexity, the process of making chipboard can be fully automated with the incorporation of electronic drives into each phase of the material’s processing.
Endless-screw mechanisms use a two-piece arrangement of a pinion and crown wheel to transmit movement between axles that are perpendicular to each other. They provide a compact way of reducing speed and increasing torque, particularly on small electric motors – which generally operate at high speed and low torque.
Pressing and drying
Pressure is progressively applied to the flat surface of the board during this process, until the desired caliber is achieved. The pressing rate depends on the caliber specified (the greater the caliber, the lower the speed).
The boards leave the press to be cut and then placed on rotating elements designed to let the boards cool down for stacking and packing
