Metallic wires
Experts for any application and all types of cardsMetallic wires made by Trützschler Card Clothing(TCC) for:
� Licker-in� Cylinder� Doffer� Feed rolls in the tuft feeder and in the card� Take-off rolls
TCC metallic wires stand out on account of opti-mised tooth geometries, low tolerances and a high surface quality. Comprehensive quality checksguarantee a reproducible high quality.
Here a licker-in wire is checkedto ensure the cross-section
geometry and the surface qualityare maintained. This is important
for trouble-free start-up of themachine

Cylinder wiresAs we use high-grade, micro-alloyed steel qualities,our cylinder wires stand out on account of theirlong service life and at the same time low mainte-nance expenditure. Precision in manufacturing andoptimised tooth geometries guarantee a substan-tial reduction in neps and dirt particles.
TCC cylinder wires are also available in NovoStarquality (see special brochure) for special require-ments with regard to a high card production andsimultaneous long service life.
Doffer wiresTCC doffer wires excel particularly in safe runningproperties with a high level of production. A spe-cial surface quality prevents the accumulation offoreign particles in the wires.
Side grooves on every tooth ensure safe web guiding. The risk of damage is lower because thesedoffer wires are run at a higher distance from thecylinder than usual.
TCC doffer wires are universally applicable andmaintenance-free.
Licker-in wiresA long service life is achieved by using specialsteel qualities. TCC therefore uses only the particu-larly high-grade NovoStar steel quality for the licker-in wires.
Based upon this, optimised tooth geometries adapted to the raw material and to the licker-inarrangement ensure a gentle pre-opening of the fibre material.
TCC licker-in wires are available as interlinkedwires and for mounting in grooves.

Flat tops
TCC-TOP flat tops: foundation and hooks makethe differenceFlat tops mainly consist of the foundation and of the hooks. Both of them have an enormous influence on carding quality.
We use a “multi-layer foundation” in the web con-struction, with the covering layer always consistingof a permanently elastic natural rubber. A foun -dation consists of up to seven single layers thatare constructed like a sandwich.

The constituted wires of micro-alloyed steel areadditionally hardened by TCC. Computer-optimised,biconvex wire cross-sections and the special geo -metry of the points (only half as wide as a cylinderwire point) reduce wire movement during the carding process. This prevents excessive breaking.
Quality right from the startApart from the quality of the foundation and of the hooks, the careful manufacture of the flat topsis important, of course. This starts with the so-called setting, i.e. inserting the hooks into thefoundation.

Precision from grinding to finishingAfter the setting procedure, the time-consuminggrinding procedures are carried out. First, the sur-faces of all hooks are levelled in consecutive work-ing steps. Then side grinding is effected using spe-cial grinding elements to make the hooks as smallas possible in the carding direction. The next grind-ing process forms the back of the wires. This iscalled back grinding. Finally the surface is refined.
Three grinding procedures form thehook tips
Grinding the flat tops calls for extensive experience and competence
All TCC-TOP flat tops are hardened at the tips ofthe hooks. This prolongs the service life and keepsthe flat sharp for a longer time.
Flat tops are also available in NovoTop quality (seespecial brochure) for particularly high requirementsregarding card production with simultaneous extra-long service life.
Of course, TCC offers all the necessary flexible fillets for stripping and cleaning rolls, too.

Carding segments: uncompromising qualityTruetzschler carding segments – also called station-ary flats – are manufactured from a special steel ofNovoStar quality only. It is at the carding segments,particularly in the pre-carding zone, that the highestforces and thus the highest wear of the wire. For this reason alone ”standard qualities“ are out ofquestion for TCC. We focus on a longer service life,constant quality and a reduced maintenance cost.

Optimised geometries for optimum productionThe high card production levels that are possibletoday have been attained last but not least by ahigher number of stationary flats and by the devel-opment of new wire types. Here on the one hand agood retention of the fibres must be ensured, but on the other hand the carding segments must not beclogged. Both aims are achieved by optimisedgeometries.
TCC offers a wide range for equipping the segmentswith wires. It lies between 90 and 640 ppsi (14 - 100 points/cm2).
Modern high-production cards operate with an everhigher number of carding segments

Numerous variations and durable sharpnessCarding segments are not only used in the pre- andafter-carding zones of the main cylinder, but also at the licker-in rolls. In combination with most different types of cards and clothing finenesses,this results in a multitude of variants.
The wires of the carding segments are notreground, therefore tight manufacturing tolerancesare so much more important. This precision mustalso be maintained after mounting the wire on therespective card-specific support.
