Rieter . High-Performance Card C 75 C 75 - the Card for Every Application This is thanks to the combination of a large active carding area and optimized pre- and post-carding zones Key features of the carding area The 32 engaged flats are a crucial factor in ensuring the yarn quality on the Card C 75. As well as a work area of 1.5 m, the C 75 also has one of the largest active carding areas. The active carding index (ACI) is a parameter for the effective carding area - the number of engaged flats is multiplied by the card working width. The table contains card models with different ACIs and...

Rieter . High-Performance Card C 75 Optimal Raw Material Utilization Savings thanks to more selective trash extraction Savings with selective trash extraction With selective trash extraction, you determine the economic success based on intelligent utilization of the raw fiber material and targeted quality of the end product. Potential for savings is considerable, as is shown in the graph titled “Savings potential with the C 75 depending on the price of cotton and percentage of waste (based on an 800-kg/h card line production).” Savings potential with the C 75 depending on the price of...

Rieter . High-Performance Card C 75 Q-Package 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 lowwear 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. Insert fine 2 mm Inserts are...

Rieter . High-Performance Card C 75 The C 75 has an additional option for separate licker-in waste disposal, which has an extremely short payback time. This means that 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 spinning mill by means of a recycling line for the production of yarns. Plant with separate suction for licker-in waste removal Features of the separate licker-in waste disposal are: • Very economical, intermittent waste removal, which is integrated into the waste transport of the...

Rieter . High-Performance Card C 75 Unique Integrated Grinding System IGS Ensures consistent quality and increases the service life of the clothing by 20% 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 right from the start by keeping the clothing permanently sharp. IGS-classic keeps the cylinder clothing sharp In the IGS-classic, a grinding stone is automatically moved across the cylinder clothing during production. This operation is performed 400 times over the...

Rieter . High-Performance Card C 75 IGS-top additionally sharpens the flat clothing Time required IGS-classic Time required Manual grinding IGS-system IGS-classic and IGS-top Cylinder grinding Flat grinding The IGS-top sharpens the card flat clothing fully automatically. The control unit calculates the grinding cycles over the pre-selected service life of the card flat clothing. Numerous small grinding operations ensure that the quality is more consistent than in a flat grinding roller, with fewer, aggressive, manual grinding operations. Clothings after 240 tons of production, with IGS-top...

Rieter . High-Performance Card C 75 The Blueprint for Low Energy Consumption Is in the Machine Design Lower energy consumption than all other cards Card C 75 – the green card With yarn production, energy consumption represents an important price factor. With Rieter spinning machines, the 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 75 exhibits an energy consumption that is 20% lower (kW per kilogram...
