High Production of up to 225 kg/h Proven 1.5-m carding technology Innovative technology for outstanding performance The card C 77 utilizes the proven 1.5m Rieter carding technology and offers a high production. Together with the exceptionally low energy consumption, an economical production is guaranteed. 32 active flats support an outstanding sliver quality. These flats and the working width of 1.5 m are the main reason for the high performance of up to 225 kg/h. Decisive for a high production level and excellent carding result is the permanent precise carding gap over the whole machine...

Energy Savings of up to 30% Lower energy consumption than any other card Card C 77 – The ecological card Efficient suction system Among the features that make the card C 77 so energyefficient are: • the compact design with a small machine footprint • small rotational masses • optimal pre- and post-carding area • 32 active flats • energy efficient drives • high production of up to 225 kg/h The design of this suction system contributes to the low energy consumption of the card C 77. Easy maintainability is granted by the components which are attached with quick-release couplings. This...

Excellent and Consistent Card Sliver Quality Precise carding cap with 32 active flats and a large carding area Total flats Working flats Active Carding Index (ACI) This is the main reason why the C 77 performs better than any conventional card on the market. Typically, the C 77 has a 71% larger active carding area than a 1-m wide card. The basis for the high production and simultaneous good quality of the carded sliver is the number of flats in working position. In addition, the working width of the card is included in the calculation. The working width, in meters, is multiplied by the...

Intergrated Grinding System (IGS) The continuous wear of the card clothing becomes more important for highly productive cards. The Integrated Grinding System (IGS) – exclusive to Rieter – solves this problem right from the start by keeping the clothing permanently sharp. IGS-classic With IGS-classic, a grinding stone is automatically moved across the cylinder clothing during production. This operation is performed 400 times over the expected service life of the clothing. Spread over the service life of the cylinder clothing, the programming of the grinding schedule calculates the optimal...

Card sliver formation The card sliver formation takes place over a dynamically controlled web transport that consists of two cross aprons and a pair of disk rollers. It is therefore possible to reliably produce fine slivers [4 ktex] at a high delivery speed. Patented pressure control Course of the batt weight over 24 hours The patented pressure control in the card chute enables a precise batt weight at the card feed, considering the raw materials and their characteristics. The result is a minimal variation [CV%] of the batt weight. New, patented pressure control in the card chute Low...

Excellent Raw Material Utilization Basis for economic success Q-Packages in pre- and post-carding zones Influencing the waste composition by the strength of the inserts Inserts can be changed more quickly and easily for variable trash extraction. The optimal raw material utilization resulting from the low wear mote knife with differing extraction width in the pre- and post-carding zones is extremely profitable. Inserts can be replaced in the shortest possible time, without using tools. Four designs are available for the different degrees of contamination – open, fine, medium, and strong....

Variable flat speed Waste extraction with variable flat speed The speed of the flats can be continuously adjusted to match the production and quality via a frequency converter – independent of the cylinder speed. This means that the card is perfectly suited to the raw material being used. 0.10 Speed [m/min] Fiber The continuously adjustable flat speed is set to the most economical level. Savings with selective trash extraction Adjustable licker-in knives, variable Q-Packages in the pre- and post-carding zones, and an electronically adjustable flat speed enable selective trash extraction....

HYPERTOP from Graf The card clothing HYPERTOP from premium wire supplier Graf is available for the new generation of Rieter cards. Investigations show that HYPERTOP wires contribute to an improvement in fiber yield by up to 0.5%. A strong wire and optimal teeth shape result in a constant high quality over an extended lifetime. The multi-zone setting pattern ensures optimal and gentle defibering. The progression from straight gaps to a gapless pattern processes the fibers with growing intensity, delivering the yield improvement. The new setting pattern favors the removal of short fibers and...
