| Abstract | ||||
| With the great development in the technology of manufacturing knitting machines, and high productivity. There are still some drawbacks that might be overcome by applying novel measurement methods, particularly, in the circular single Jersey knitting machines. The most important of these drawbacks is the laddering defects. In this paper, an online quality control system - the first of its kind - was developed and assembled on the machine and consists of a transmission unit (laser) and a receiving unit (photocell), to detect laddering defects in real-time. Once occurred, the system beeps to draw the attention of the operator and the machine stops automatically, the machine then runs again after the defect is being fixed. Thus, this system can reduce the production of the second degree, raise the level of quality, and reduce the production costs per kilograms of the produced fabric. This system proved its sensitivity and efficiency while the machine runs at the typical production speeds. | ||||
