Spinning Preparation Double-Head Autoleveler Draw Frame RSB-D 26 Double-Head Autoleveler Draw Frame RSB-D 26 The best sliver quality at highest productivity

Best Quality

Independent sides of the machine and precise autoleveling guarantee high sliver quality on both sides.

Depending on the fiber material, the double-head draw frame produces up to 33% more sliver compared to the previous model.

The drive concept reduces the number of belts required by 23%. This, in turn, saves on energy costs.

Rieter . Double-Head Autoleveler Draw Frame RSB-D 26 Outstanding Sliver Evenness The RSB autoleveler with maximum scanning precision and autoleveling dynamics Autoleveling begins with scanning precision The quality of the autoleveler is important for outstanding sliver evenness. Perfect autoleveling begins with precise scanning of the feed slivers. Compared to other “tongue-and-groove” systems, the RSB-D 26 scans the sliver with tiny scanning disks. Thus, a short piece of sliver is always located between the disks. Precise autoleveling requires highly accurate measured values. Thanks to the...

Rieter . Double-Head Autoleveler Draw Frame RSB-D 26 Quality Through Specific Fiber and Sliver Guidance Modern drafting system technology Optimal fiber guidance Conventional sliver guides in front of the drafting system pose a risk of incorrect adjustments. The most common consequence of this is non-centric guidance of the slivers and the resulting disturbing faults in the yarn. Rieter’s patented sliver guide guarantees centric guidance of the slivers at all times and ensures consistent sliver quality. The web width is reproducible and is set by a simple turning of the guide elements. The...

Rieter . Double-Head Autoleveler Draw Frame RSB-D 26 High Productivity High delivery speed with consistent quality High delivery speeds High efficiency The RSB-D 26 produces sliver at a delivery speed of up to 1 200 m/min. Depending on the fiber material, the average speed is up to 33% higher than the previous model. And with consistently high sliver quality. The draw frame has high production efficiency. The machine has two independent machine sides. When one machine side is at a standstill, the other side continues to run. The maintenance and cleaning requirements are low. Lot changes can...

Rieter . Double-Head Autoleveler Draw Frame RSB-D 26 Low Energy Consumption New drive concept Energy-saving drive concept The draw frame RSB-D 26 requires 23% less belts and drive elements compared to the previous model. A patented drive concept with two servomotors drives the drafting system. The individual drive of the coiler replaces the twisted belt thereby increasing its lifetime. The new separate drive for the can plates combines convenience and quality during sliver coiling. The low friction is the basis for the low energy consumption. Due to the frequency-controlled drive,...

Rieter . Double-Head Autoleveler Draw Frame RSB-D 26 Clean, Consistent Coiling Quality and Good Downstream Processing Innovations in sliver coiling Preventing deposits CLEANcoil is the standard coiler for all fiber materials and therefore offers maximum flexibility. The spiral coiling tube ensures sliver coiling that is free of drafting faults, even at high delivery speeds. The honeycomb structure on the coiler underside reliably prevents deposits. The patented new coiler CLEANcoil-PES has a new type of coating. Even with hard-to-process polyester fibers, the production time until the next...

Rieter . Double-Head Autoleveler Draw Frame RSB-D 26 Precise first sliver layers A light barrier ensures controlled sliver coiling. It recognizes when the first sliver layers are on the coiler. Only then does it switch from the reduced to the full production speed. This ensures consistent sliver and yarn quality, even for cans with plates that are too low. Precise sliver coiling from the very first meter prevents tangles in the subsequent processes and breaks when drawing the sliver out of the can. The cans therefore run without interruption until they are completely empty. This maintains...

Rieter . Double-Head Autoleveler Draw Frame RSB-D 26 Consistent Yarn Quality in Downstream Processing Efficient suction High sliver quality Dust deposits in the drafting system can be avoided. Due to the intermittently lifting cleaning lips on the top rollers of the RSB-D 26, trash deposits enter directly into the suction system. Sliver funnel blockages are therefore demonstrably reduced. This improves yarn cleanliness. Imperfections and Classimat faults are reduced. In addition, the number of yarn clearer cuts is significantly reduced. Intermittently lifting cleaning lips to prevent dust...

Rieter . Double-Head Autoleveler Draw Frame RSB-D 26 Online quality monitoring The Rieter Quality Monitor (RQM) continuously checks the sliver count of the delivered sliver using a movable calender roller. The RQM works independent of the autoleveler unit. It automatically stops the draw frame if the preselected limit values are exceeded. The spectrogram also visualizes shortest wavelengths and thus confirms the precision of the measurement. This reduces the number of sliver tests in the laboratory. For more advanced analyses of the measured values, it is possible to connect the RQM to the...
