  3. 3. Brief Mesdan history Ø since 1952: knotters Ø 1980: 110 hand-operated air splicer (Jointair) Ø 1982: 905 automatic splicer for Savio Ras Ø 1986: 927L automatic splicer for Savio Ras Ø 1987: 114 hand-operated splicer and A.T.S. Ø 1990: wet splicer (Aquasplicer) Ø 1991: the new Mesdan-Lab division was born and 490L for Espero Ø 2004: obtained the ISO 9001 and 14001 Quality Certificate, launched the M.K.F.A Ø 2007: hot-air splicer (Hot Jointair) Ø 2009: 8 new important idems added to Mesdan-Lab range

In 1980’s almost 100% of joints with the automatic winders were done with knots. In 1990 this share was around 8%, while today is lower than 1%.
  5. 5. During the various textile operations the yarn: - is subject to many breaks - needs tail-to-top connections HOW TO MAKE THE JOINING?

  10. 10. KNOT PROBLEMS: EFFICIENCY - holes and needle breaks on knitting machines - entanglement and yarn breaks on the loom PRODUCT FINAL QUALITY - second quality selection due to knots presence - each loom stop means a visible fault on the fabric COSTS - fabric mending - waste
