  1. 1. 12 tearing sleeves - analyse• Misapplication of handling: incorrect stretching
  2. 2. 12 Analyse - tearing sleevesmethods of analysis• Ishikawa with interdisciplinary Team•assessment of return shipment / defectet parts•Own compression-tests at return defectet partsexcluded failure-cause:•Spuriousness bonding of materials– Monitoring by new control mode of machine, temperature-monitoring, etc•failure of raw material from supplier– comparison of material certificate showed no changes; adhesive application, glassfabric, thread-count without difference•Personal has adequate training
  3. 3. 12 Analyse - tearing sleevesmeasured (possible) causes:•No errors of this type for other customers, so we guess it is an individualhandling mistake by customer.•Own tests (> 200) showed 100% clearly result: 200 parts tested:•100 parts tested by Westaflex-requirement: compression and stretching;100 parts OK•100 parts tested against Westaflex-requirement: compression andstretching; 100 parts NOK•until now there is no described operator instruction for handling, it willoccur temporarly to broken sleeves
