Carpeting is a wonderful choice for flooring in both residential spaces and commercial areas. Many carpets are manufactured to be durable, beautiful and stain resistant. However, one of the most eye-catching problems with carpeting happens during the manufacturing process when J-cuts are made. But how do J-cuts in carpeting occur?
During manufacturing, a tufting machine threads the carpet fibers to the backing securely. A series of knives, known as a looper, is supposed to cut the fibers in the middle of the yarn loop. However, sometimes the looper makes the cut to one side or the other of the carpet fiber, creating a row of carpet tufts that are short on one side and high on the other. This usually happens when the looper is dulled.
The resulting line of low and high fibers is known as a J-cut because when the fiber is pulled out, it resembles the letter J with a high side and a low side. Such an error is definitely noticeable in pile carpeting because there will be a high line and a low line. Sometimes the error can be fixed by trimming the high line to the height of the rest of the carpet. However, this won’t always help.
