Excellent Raw Material Utilisation

Selective trash removal thanks to the adjustable knife on the licker-in, inserts on the Q-package and varying flat speeds optimise raw material utilisation. 5

The unique IGS system guarantees consistent sliver quality during the lifetime of the clothings. In practice, this increases the service life by up to 20 %. 6

Consistent Sliver Quality

Largest Active Carding Area Consistent Sliver Quality Maximal production is derived from the largest active carding area Short Downtimes IGS – ensures permanently sharp clothings and increases the clothing service life Quick adjustment to raw materials due to modular design AEROfeed Supplies up to 10 cards in one line with 1 200 kg/h line production Excellent Raw Material Utilisation Selective trash removal in the carding process 8 Sophisticated Solutions from Start to Finish Intervention-free machine operation due to absolutely uniform batt weight and web formation

Compact design with small moveable masses Everything under Control High production and sliver quality with the reliable levelling of the card and controlled fibre guidance Process Shortening Quicker material throughput with draw frame modules

Rieter . C 70 High-Performance Card No Other Produces More The combination - largest active carding area and precise carding gap - Key factor carding area Active carding area Decisive for the carding result is stiii the precision of the carding gap over the whole machine width. The card- material processed. Due to the precise flats guidance, the tight tolerances and the material combination, cast-iron plate with cast-iron cylinder, the carding gap also adheres exactly to the predefined setting during operation. Decisive for the yarn quality on the cards is the number of the card flats in...

Rieter . C 70 High-Performance Card Optimal Raw Material Utilisation Savings thanks to more selective trash removal Savings with the selective trash removal With the selective trash removal, you determine the economic success based on intelligent utilisation of the raw fibre 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). Range of cotton prices Savings potential with the C 70 depending on the cotton price...

Rieter . C 70 High-Performance Card Q-package in pre-and post-carding zone Influencing the waste composition by the strength of the inserts Quicker and easier exchange of the insert elements for selectable waste extraction Extremely profitable is the optimal raw material utilisation resulting from the low-wear mote knife in the pre- and post-carding zone with differing extraction width. Inserts can be replaced in the shortest possible time, without using tools. For the different degrees of contamination, four designs are available – open, fine, medium and strong. Insert fine 2 mm The...

Rieter . C 70 High-Performance Card Separate licker-in waste disposal 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. Plant with separate suction removal of the licker-in waste Licker-in waste Example Production (12 C 70 with 95 kg/h) Yearly working hours Total card waste Licker-in waste Mixed waste...

Rieter . C 70 High-Performance Card Unique Integrated Grinding System IGS Ensuring consistency of quality and increasing 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 from scratch by keeping the clothings constantly sharp. IGS-classic keeps the cylinder clothing sharp With IGS-classic, a grindstone is automatically moved across the cylinder clothing during production. This operation is performed 400 times during the expected...

Rieter . C 70 High-Performance Card IGS-top additionally sharpens the flat clothing Time required Manual grindin Time required IGS-System IGS-classic and IGS-top Cylinder grinding Flat grinding The IGS-top sharpens the flat clothing fully automatically. 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. Clothings after 240 tonnes production, with IGS-top (left),...

Rieter . C 70 High-Performance Card The Recipe for Low Energy Consumption is Found in the Machine Design Lower energy consumption than all other cards C 70 card – the green card A large price factor with yarn manufacture is the energy consumption. With Rieter spinning machines, 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 C 70 card exhibits an energy consumption that is 20 % lower (kW per kilogram of...
