Splicer is one of the fastest development to be commercially introduced in
the textile industry. 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. During the various textile operations the yarn:
- is subject to many breaks
- needs tail-to-top connections
HOW TO MAKE THE JOINING?

6. ... knotting
3 main kinds of knots:

7. KNOTTERS - manual or automatic
Automatic knotter 410
Manual Fishermans knotter

DIMENSIONS

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

11. ... splicing
SPLICER GUARANTEES
100% KNOTFREE YARN PROCESSING
-ELIMINATES THE DEFECTS ON THE FINAL PRODUCT
-IMPROVES MACHINE’S EFFICIENCY
-REDUCES WASTE
-MANPOWER SAVINGS (MANDING COSTS)
-IMPROVES COMPETITIVENESS!!!

12. ... splicing, a MUST
for yarn and fabric QUALITY.
Mesdan developed SOLUTIONS for every kind of yarn
process and machine, from winding, twisting, ..., up to
weaving (both for warp or weft) included
TARGET:
100% knotless plied yarn

For the hygroscopic yarns (cotton, linen, etc.) when adding a
drop of water the splice strength increases considerably.
The wet splicers are indispensable to join:
-Twisted cotton
-O.E. Cotton
-Gased cotton
-Mercerised cotton
-Compact cotton
-Elastic cotton
-Linen

the splice on variuos materials:
- High twisted worsted yarns
- Wollen yarns for carpet
- Single wool “compact” yarns
- Twisted wool yarns for weaving
- Single and twisted OE viscose yarns
- Single and twisted polyester OE yarns
- Air textured yarns (taslan)
- Spun silk yarns

27. Splice strength control: Splice Scanner III
Good splice strength depends on:
Ø correct setting
Ø appropriate configuration
Ø stable air pressure
Ø sufficient air volume
Ø adequate maintenance

28. … therefore the monitoring of splice strength nearby the
machines is of paramount importance
Options:
manual checking or by means of a simple force gauge
Ø subjective and not registrable
Splice Scanner: transportable, quick, easy, precise …
Ø objective with data print-out

29. YARN JOINING DIVISION
… Splice Scanner III incorporates a
specifically designed testing mode for splice
assessment on automatic winders:
a) few tests on parent yarn as reference
b) set the acceptable strength tolerance
c) test the splice strength on each drum
Results:
Ø indicates the number of drums outside tolerance
Ø provides data and statistics print-out
