When talking about tension or force, it is important not to confuse this concept with the one used in the operation of circular saws.
When talking about tension or force, it is important not to confuse this concept with the one used in the operation of circular saws.
In this case, the tension is mentioned for the characteristics of the pressure (measured in pounds) that holds the pulleys at a certain distance, as well as ensuring the sawing process itself.
Proper tension is the key to high–quality wood processing, so it is important to constantly monitor this indicator.
In the event that the tension (force) is insufficient, the canvas will slip on the pulleys and run idle, or it may fly off the pulleys altogether.
When the tension is too strong, strong vibrations can occur, the canvas will overheat and quickly collapse.
Any of the deviations will lead to a decrease in the quality of wood processing!
There are three different ways to provide the necessary effort: by means of springs; by means of hydraulics; by means of pneumatics.
Such different techniques inevitably lead to the development and application of tension measuring devices.
As a rule, such devices are installed directly on the machine.
Regular checking of force indicators, as well as ensuring the serviceability of all machine elements, will not allow the settings to go wrong and allow defects during processing.
If we talk in more detail about tension measuring devices, then we can mention the Nordex refractometer.
Using this device, you need to adhere to the figure of 25,000-28,000 pounds per inch of canvas.
This will be a normal working tension!
