On a glass or carbon fiber warp knitting multiaxial machine, there are thousands of hook pins to hold the layed fibers in place. If pins get broken, the fibers cannot be layed creating gaps and loose elements in the fabric. If this is not detected, the entire manufactured fabric may become waste or second quality. Not only this, but also there might be a mechanical reason for a pin to break such as weft carriers travelling beyond the limits and crashing into pins. If these are not detected immediately, then the entire conveyor pins may get broken resulting in a huge amount of work loss, material and spare part cost. BTU-TECH developed a pin break sensor that is independent of the pins spacing, travelling speed and accelerations/deccelerations. More than 10 systems were delivered and installed to customers in Asia, Europe and America.
