It is always suggested to use a webbing cutter while cutting weave webbings and Polypropylene Ropes to ensure getting the best outcomes. A webbing cutter works based on melt-cutting under temperatures of 170 to 180 degree Celsius. While cutting ropes, it is needed to follow safety precautions to avoid any sort of burn from the molten rope or blade. So be careful about that. Remember that there is higher temperature at the place of incision as well as a couple of centimeters from that point as well.
This simple device applies the principle of resistive wire while cutting. The cutting procedure is done with the help of a heated thin stationary cutting tool or blade. The blade positioned on the upper side is equipped with small cutting edge. They are long enough to properly cutting thick ropes.
Maintaining the right temperature of the cutting blades is important. Anything less than the melting temperature of propylene extends the period of cutting. Also, holding rope on the blade for longer period of time can lead to a choppy cut of the rope. On the other hand, if you maintain a higher temperature, there might be unnecessary overflow and degradation of the material. The webbing cutter is set to the right temperature and it is being maintained all through the process.
While working with such a cutter, you can keep both your hands free and achieve a bevel cut. There are small hand cutters as well. But, those tools require you to hold it with your hand making it difficult to cut at any specific angle.
Let's check out the cutting procedure
Polypropylene Ropes for producing harnesses and leases have to be cut at an angle between 45 to 55 degrees. Hold the rope with both hands and start cutting it from the thicker side to the thinner side gradually. This way you can achieve desired angle while ensuring a sharp edge for the tip without any splitting.
Avoid pressing polypropylene ropes under huge pressure and against resistance. The cut is done with a balanced combination of a sideways cutting movement and pressure. After cutting the rope properly, don't forget to seal the cutting edge smoothly.
Make sure you put proper cutting pressure and speed on the rope. And this can be only done with thorough practice and reasonable experience. If you opt for slow cutting, a large quantity of material will be molten creating overflow. On the other hand, fast cutting may lead to splitting tips.
Polypropylene rope may be perfectly sealed with tape prior to the cut. This helps you cut until you obtain needed experience. By sealing the rope, you are actually making the rope homogenous and easy to cut. However, be careful, especially if you are dealing with a thicker rope. Also, sealing the rope too tightly may not help with proper cutting. The molten material is likely to stick to the tape that you can hardly remove later.
These products are better than the conventional mono ropes. The coil lengths vary from 110 metres to 330 metres and are available in 3 strands. To avail ropes of longer lengths, feel free to contact Crown Industries anytime.
