Compact Spinning K 42 Compact Spinning Machine K 42 Compact Spinning Machine OUTSTANDING FEATURES TECHNICAL DATA Fully-compacted yarns economically produced ADVANTAGES OF THE COM4®COMPACT YARN THE COMFORT OF COMPETENCE

Comparison measurements show that the central suction duct with a large cross-section combined with the air guide element significantly reduces the energy consumption.

Excellent Yarn Quality 4

The unique suction drum system and the new suction inserts ensure high and sustained consistent yarn quality.

High Profitability

Low investment costs due to the mechanical drafting system gear drives make the K 42 an attractive proposition. 7

Rieter . K 42 Compact Spinning Machine Highest Quality and Reliability Unique compacting system Proven suction drum system The solid suction drum remains the basis for longterm, consistent quality in compact spinning. The low-wear surface ensures a good and especially uniform yarn quality over long operating periods. Air guide element The suction drum system is the only compacting system that offers high machine efficiency without extensive maintenance and cleaning. Suction drum By means of the optimal and constant air flow with the suction insert “Bright”, the fibres are optimally...

Rieter . K 42 Compact Spinning Machine Quality Monitoring Air guide element “Detect” secures and monitors the quality Quality through specific air flow The air guide element “Detect” ensures precise air flow. In combination with the suction drum and the suction insert, this achieves the optimal compacting result. The lateral inflow of the air captures all fibres and binds them reliably into the yarn strand. Yarns with highest strength and lowest hairiness are the result. Compacted fibres Air guide element Suction drum Suction insert Quality monitoring through air guide element “Detect” The...

Rieter . K 42 Compact Spinning Machine Energy-Saving Compacting Up to 63 % less energy for compacting Low energy consumption due to one-duct system and air guide element The Rieter compacting system has the lowest energy consumption of all compact systems. The central suction duct reduces the energy consumption needed to generate the vacuum. By means of the large cross-section the air resistance is reduced and consequently the energy input. The compacting zone is covered by the air guide element. The optimally guided air flow reduces the air volume required for compacting to a minimum. In...

Rieter . K 42 Compact Spinning Machine Energy-Saving Drive Rieter 4-spindle tape drive uses minimal energy The Rieter 4-spindle tape drive is energy saving and easy to handle. With the 90° enlacement on the spindle, a good drive of the spindle can be secured with a low contact pressure. This contact pressure ensures minimal force on the spindle bearings and thus secures the lowest possible energy consumption. The large speed range with optimal efficiency secures the necessary flexibility, as a wide yarn count range can be operated with low power consumption. With major changes in the speed,...

Rieter . K 42 Compact Spinning Machine Economic Machine Concept Mechanical drafting system drive reduces investment costs Cost-efficient production For constant production with infrequent changes in the yarn count, the mechanical drafting system drive is a good solution. In yarn production, in addition to the ongoing energy and personnel costs the investment costs are of great importance. A machine with mechanical drives is the ideal solution to keep these costs low. Intermediate drive ensures flexibility and quality Long machines use an additional drive unit for the middle bottom roller,...

Rieter . K 42 Compact Spinning Machine Easy Machine Setting Important functions are set centrally on the display Easy entering of the spinning data Important machine functions are centrally entered. The various menus of the machine control simplify the entry process. The operator is guided step by step through the menu. As important lot data such as yarn count, twist and speed curve are centrally set, the time required for a lot change is reduced. Reliable machine setting If in large plants many machines produce with the same yarn count, it is important that the quality on all machines is...

Rieter . K 42 Compact Spinning Machine Efficient Doffing High productivity through fast and reliable doffing Doffing without unterwinding With the SERVOgrip, no yarn residues occur that need to be removed from the wharve. As well as saving yarn, it helps to keep the machine clean. Ends down caused by flying yarn remnants are avoided. Rieter is the only manufacturer to offer an exactly controlled clamping crown. The controlled opening and closing of the clamping crown by the ring rail fixes the yarn exactly and ensures a low number of ends down after doffing. In addition, the risk that fibre...

Rieter . K 42 Compact Spinning Machine Reliable cops transport through SERVOdisc The SERVOdisc system works with peg trays that are clipped into a conveyor belt. This achieves a high level of precision in positioning. During doffing, the full cops and the empty tubes can thus be precisely taken over and removed. High dependability and short doffing times guarantee high machine efficiency over a long period. The SERVOdisc system is an open system and is thus practically self-cleaning in all circumstances. It is driven by two diagonally offset 70 watt motors and comes with 10 % of the energy...
