For an always satisfying performance of the weft feeder over the years, we deem it advisable to provide you with some simple tricks: 1. At the time of installation, passing from the store to the warm weaving environment, Condensation may form on a weft accumulator that has been stored in cold places when this is brought into a warm area.
  • Page 6 CAUTION 5. In the presence of dusty yarns, residual dust or thread may settle on the various parts of the weft feeder. A weft feeder that is particularly dirty is likely to compromise the fabric quality by leaving deposits on the threads that is introduced.
