Rieter . High-Performance Card C 70

No Other Produces MoreThe combination – largest active carding area and precise carding gap – is the reason

Decisive for the yarn quality on the cards is the number of the card flats in contact across the working width. The C 70 with 32 flats in working position and 1.5 m working width has the largest active carding area and thereby differs significantly from other card models.The active carding index (ACI) is a parameter for the effective carding area – the number of flats that engage is multiplied with the card working width. Based on the table, various card models are listed in the ACI and explain logi-cally why the C 70 performs such good carding work.

Active carding area

1 m = 100%1.28 m = 128%

C 70: 1.5 m = 171%

Working width [m] 1.50 1.00 1.28

ACI 48 28 35.8

C 70 advantage – 71% 34%

Decisive for the carding result is still the precision of the carding gap over the whole machine width. The carding gap is set according to the production and the raw material processed. Due to the precise flats guidance, the tight tol-erances and the material combination, cast-iron plate with cast-iron cylinder, the carding gap also adheres exactly to the predefined setting during operation.

Optimal Raw Material UtilizationSavings thanks to more selective trash removal

The mote knife on the licker-in is quickly adjusted for optimal raw material utilization as well as flexible adaptation to various raw materials. The C 70 offers optimal configuration possibilities for every practical requirement. The manual ad-justment allows adaptation of the mote knife. An automated version is optionally available which makes adjustment of the mote knife possible during production.

With the selective trash removal, you determine the economic success based on intelligent utilization of the raw fiber material and targeted quality of the end product. Potentials for saving are considerable, as is shown in the graph Savings potential with the C 70 depending on the cotton price and waste percentage (Basis 800 kg/h card line production).

Yearly saving USD 54 104

The separate disposal of the licker-in waste is an option of the C 70, which has an extremely short payback time. Hence the cleaner, more valuable flat waste is separated from the dirtier licker-in waste. This is either resold as valuable raw material, or is fed into the yarn production in the spinning mill by means of a recycling line.

Separate licker-in waste disposal

Plant with separate suction removal of the licker-in waste

Features of the separate licker-in waste disposal are:• Very economical, intermittent waste disposal, that is inte-

grated in the waste transport of the blowroom and there-fore does not generate any additional air requirement.

• A visual assessment of the waste composition is possible at any time.

• The waste box on rollers allows easy handling with main-tenance and repair work.

Unique Integrated Grinding System IGS Ensuring consistency of quality and increasing the service life of the clothing by 20%

With IGS-classic, a grindstone is automatically moved across the cylinder clothing during production. This operation is performed 400 times during the expected service life of the clothing. Spread over the service life of the cylinder clothing, the programming of the grinding plan calculates the optimal distribution of the grinding cycles.

IGS-classic keeps the cylinder clothing sharp

400 times

Manually ground / ground with IGS-classic (400 times)

Manually ground Automatically ground

The continual wear of the card clothing gains in importance with highly productive cards. The integrated grinding system IGS – exclusive to Rieter – solves this problem from scratch by keeping the clothings constantly sharp.

15


With IGS you save money

In practice, it has been shown that the life cycle of the cylinder clothing is extended by 10 – 20% in all appli-cations through the use of IGS-classic. In addition, the savings gained from the lower maintenance requirements are evident. Furthermore, the machine downtimes neces-sary for manual grinding are eliminated.

IGS-top additionally sharpens the flat clothing

The IGS-top sharpens the flat clothing fully automati-cally. The control calculates the grinding cycles over the pre-selected service life of the flat clothing. Through the many small grinding operations, the quality remains more constant in comparison to that with fewer, aggressive manual grinding operations of a full grinding roller.

The Recipe for Low Energy Consumption is Found in the Machine DesignLower energy consumption than all other cards

Card C 70 – the green card

A large price factor with yarn manufacture is the energy consumption. With Rieter spinning ma-chines, focus has always been placed on low energy consumption. With the introduction of the 1.5 m technology, the energy consumption of the cards has been drastically reduced. As a consequence of the innovations in the area of flats, the Card C 70 exhibits an energy consumption that is 20% lower (kW per kilogram of produced card sliver).

The lowest energy balance is based on:• Maximal performance capacity• Innovative machine geometry with small,

moveable masses, as with the cylinder with larger working width

• Precise machine construction, e.g. exact flats distance

Modular design

Replacement of the licker-in, flat and doffer clothing with conventional cards is a time-consuming maintenance operation. The modular construction of the C 70 reduces these downtimes to minimal values never before achieved. All three modules are even quicker to replace with prepared optional spare modules. Each of these operations requires just one person from the main-tenance staff. For instance, the licker-in module can be complete-ly replaced in less than 90 minutes. With the IGS-system and the modular machine concept, Rieter has taken an important step towards reducing the machine downtimes and at the same time maintaining consistently better sliver quality.

Modules increase the productivity

In addition to the modern and attractive appearance of the C 70, comprehensive ergonomic improvements are integrated. These guarantee the operator friendliness and minimal machine downtimes.

Patented pressure control

The patented pressure control (patent pending) in the card chute replaces the clas-sical light barrier control. This functions by giving a precise batt weight at the card feed, taking into account the raw materials and their characteristics. The result is a minimal variation [CV%] of the batt weight.

Man-made fibers with strongly lubricating fiber finish or cotton with honeydew tend to contaminate fiber guide elements. Here the web bridge must be frequently cleaned to maintain the quality level. The solution for this time-consuming un-dertaking is the new, patented web bridge (patent pending). In the shortest possible time, it can be removed, cleaned and reinstalled. If there is an appropriate replacement component in the spinning mill, the downtime can be reduced to a few minutes. The new web bridge allows a pefect, uniform web and ensures continuous operation of the card. Thick places are substantially reduced.

Sliver formation

The sliver formation takes place over a dynamical-ly controlled web transport, that consists of two cross aprons and a pair of rollers. It is therefore possible to reliably produce fine slivers [4 ktex] at a high delivery speed.

Short-term leveling

The feed trough measures the thickness of the sup-plied batt. The speed of the card feed roller adjusts automatically according to the values determined, so that a uniform sliver fineness is achieved.

Long-term leveling

The sliver fineness is measured by a disc roller pair at the sliver delivery. The measured signals are processed and used to control the feeding system.

From the Batt to the SliverPerfect control of the fibers for unequalled sliver quality

Card leveling

The sliver coiler CBA is extremely space-saving and op-timally adapted to the C 70. A compact sliver separation integrated in the calender unit operates reliably at full production. The sliver weight remains the same from start to finish of can filling.

Rieter drafting technology

The draw frame module of the C 70 is based on decades of unrivalled Rieter expertise concerning automatic leveling systems and the several ten thousand high-performance draw frames sold.

The integration of draw frame improves the economy and the productivity. In certain cases, application of the direct process with the rotor spinning process can optimize the yarn quality. The draw frame module is available in two versions:• C 70 SB without leveling system.• C 70 RSB with the proven Rieter leveling system.According to the yarn count, raw material and spinning technology, the number of conventional drafting passages can be reduced.

Process Shortening by Process IntegrationDraw frame module based on long established know-how

Process integration

According to the yarn count and material used, the process can be shortened by application of draw frame modules on the card. Consultation on the optimal production process is a core competence of Rieter as system supplier.

The C 70 RSB is equipped with a digital short-term leveling system. The uniformity of the Card C 70 sliver is recorded using the well-proven principle of tongue-and-groove scanning rollers. Through the application of pneumatic load on the scanning roller, complete scanning is guaranteed. Based on the measured values, the digital signal processor calculates a nominal value for the highly dynamic servo-drive. This value is transferred at the very moment when the measured piece of card sliver reaches the leveling point in the main drafting zone.

Technology

In contrast to conventional products, the RSB module uses exact sliver scanning. This guarantees a 100% leveling of the sliver, both in the normal production process and in can change mode. The resulting advantages with the draw frame module are:• Shorter and quicker production process.• 100% leveled sliver with the C 70 RSB thanks to genuine draw frame scanning.• Genuine parallelization of the fibers by up to 5-fold drafting.• Increased productivity with lower space requirements.

From cotton to man-made fibers

All the features described make the Card C 70 the ulti-mate, universal card, which is at home in every area of application. It is equipped for every requirement profile. Whether it be man-made fibers, finer or coarser cotton or blends with man-made fibers.

Card C 70 for All ApplicationsNatural or man-made fibers – the C 70 processes them

The C 70 reliably processes various raw materials and their blends

Example of a highly flexible blowroom and carding line where two different blends of cotton and man-made fibers are simultaneously produced

25


The advantage of the C 70 as a modular designed card is that it can be quickly adapted to new and familiar challenges of man-made fibers, without high-performance carding having to be reinvented. Compared to the version for cotton, several differences are visible and others can only be recognised when taking a closer look:• Fiber guiding components are made of chromium (specially coated

sheet metal).• Licker-in, cylinder, flats and doffer clothings are specifically

designed for man-made fibers produced from natural or synthetic polymers.

• The pre- and post-carding zone is accordingly equipped with card-ing elements (see graph).

The C 70 for man-made fibers

The latest development CLEANcoil-PES with a new type of coating offers unique advantages in coiling. Even with critical polyester fibers, the cleaning cycle can be extended by at least 100%. This also leads to more consistent sliver and yarn quality.
