Spinning Preparation Double-Head Draw Frame SB-D 22 Double-Head Draw Frame SB-D 22 OUTSTANDING FEATURES TECHNICAL DATA Double-head draw frame with unique can changer up to 1 000 mm

Up to 20 tons of sliver per day with machine width of only 2.98 m and unique 1 000 mm can changer.

Highest Productivity Using Minimal Space 3

Superior Classimat values in the yarn are achieved due to efficient drafting system suction with lifting cleaning lips.

Energy consumption is around 20% lower than for comparable machines due to a well-conceived drive system

Efficient Suction Several variants offer solutions for all space conditions Automatic filter cleaning and lifting cleaning lips on the top rollers Space-Saving and Ergonomic Only 2.98 m machine width with 1 000 mm can changer at optimal operating convenience Frequency-Controlled Drive Delivery speed flexibly and quickly adjustable on the display Efficient Drive Concept Around 20% lower energy consumption than comparable machines

Modern Drafting System Unique centralized setting for both heads simultaneously, large top rollers for disruption-free operatin High Productivity Max. 2 × 1 100 m/min delivery speed produces up to 20 t of best quality sliver Clean Sliver Coiling CLEANcoil and CLEANcoil-PES reduce cleaning effort Unique Can Changer Ensures high machine efficiency and reduces dependence on operator performance

Rieter . SB-D 22 Double-Head Draw Frame Unique Can Changer Concept Advantages of large can sizes and automatic can changer High efficiency due to automatic can changer up to 1 000 mm cans Unique on the double-head draw frame is the simultaneous can changer for up to 1 000 mm diameter cans. This results in longer runtimes without operator intervention as well as consistently high production efficiency. Especially in spinning mills with reduced personnel deployment, slumps in efficiency of more than 10% are avoided. Compared to conventional double-head draw frames, the productivity with...

Rieter . SB-D 22 Double-Head Draw Frame Operation sequence of the 1 000 mm can changer Two cans are filled while two further cans are in the empty can magazine (Fig. 1). After can filling has been completed, the machine stops and with a turn of 180 degrees replaces the full cans with the empty cans (Figs. 2 – 4). The machine then restarts automatically. When the operator is in the draw frame area, he opens the can change arms by means of the foot pedal and exchanges the full cans for empty cans. The can changer for cans with a diameter of up to 1 000 mm automatically replaces the cans of...

Rieter . SB-D 22 Double-Head Draw Frame Modern Drafting System Engineering Rapid batch change by central drafting system setting Gentle, precise fiber guidance The proven Rieter 4-over-3 drafting system is the heart of the draw frame. Benefits in the geometry of the drafting system and in the bearing fixture of the bottom rollers allow close cylinder spacing. The precise fiber guidance makes processing of short fiber lengths possible. Large top rollers The large top rollers guarantee interruption-free operation without lap formation as well as high durability. They keep the rotational speed...

Rieter . SB-D 22 Double-Head Draw Frame Efficient Suction High cleanliness by specific suction Lifting cleaning lips on the top rollers Trash accumulations on the cleaning lips are drawn directly into the suction through the intermittent lifting of the lips. Practical tests confirmed that fewer sliver funnel blockages due to dust accumulation on the pressure bar occurred. The increased yarn cleanliness is shown in reduced IPI and Classimat faults as well as in a lower number of yarn clearer cuts. Less frequent cleaning of top rollers The patented cleaning lips and their layout reduce...

Rieter . SB-D 22 Double-Head Draw Frame Innovations in Coiling Precise, consistent coiling quality and good downstream processing CLEANcoil and CLEANcoil-PES coilers CLEANcoil is the standard coiler for all fiber materials and therefore offers maximal flexibility. The spiral coiling tube ensures coiling which is free of drafting faults, even at high delivery speeds. A honeycomb structure on the coiler underside reliably prevents deposits. For the processing of 100% polyester, the latest development CLEANcoil-PES with a new type of coating offers unique advantages in coiling. Even with...

Rieter . SB-D 22 Double-Head Draw Frame Efficient Operation Flexibility and ergonomy united Frequency-controlled main drive Spinning mills must increasingly react even faster to their customers' delivery requirements. On the SB-D 22, the operating personnel can now set the delivery speed easily and rapidly on the machine display. This saves time and storage expenditure for drive pulleys. In addition, productivity of the draw frame can be precisely adjusted to the requirements of the subsequent process stage. The well conceived conception of the frequency inverter cooling ensures the...

Rieter . SB-D 22 Double-Head Draw Frame Lowest Energy Consumption Innovative drive concept Energy-efficient overall concept The SB-D 22 saves energy by means of an innovative drive concept. Belt drives instead of more complex drive solutions and the small number of motors and inverters keep energy consumption low. The short powertrain in comparison to single-head or other double-head draw frames as well as the highly efficient engine technology lead to low power consumption. Thanks to a well-designed drive system, the energy consumption is around 20% lower than on comparable machines. More...

Rieter . SB-D 22 Double-Head Draw Frame Service and Maintenance Concept Low maintenance costs Good accessibility Large work platforms left and right of the draw frame allow convenient maintenance of the machine. Wide opening covers allow ergonomic access to all machine components. Central lubricating strip To ensure highest reliability, the draw frame is equipped with a central lubricating strip as a standard feature, which supplies all relevant parts with lubricant. The lubricating strip has optimal access and reduces the risk of forgetting important lubrication points. Quick tensioning...
