The whole process of winding the fabric on the machine is around 3.5m, and it is just around1.5m below the inspection screen, which can not be inspected. For inspecting every roll, we recommend to add a fabric end stop sensor at feeding posion, when it detects there is no coming fabric, the machine will stop automatically to let the operater join the next roll. In this way, there will be no fabric can’t be inspected in the next rolls.
