Easy Processing of Dusty LinenViscose Blend The highly efficient suction system of the draw frame SB-D 50 enables the processing of dusty material like linen fibers. At Rieter customers the singlehead draw frame without autoleveler runs at a delivery speed of up to 800 m/min with a blend of linen and viscose. The popularity of linen has increased

The efficient suction system at the pre-draw frame reduces dust during coiling and keeps the production efficiency in the subsequent processes at a high level.
High productivity, easy handling and 13% energy savings Customers are very satisfied with the operation and productivity of the SB-D 50 at high speed. The draw frame runs smoothly and trouble-free with a blend of linen and viscose (55/45%) at 800 m/min. The easy accessibility for maintenance work and the central lubrication point also make working with the SB-D 50 convenient for the operator. Six machines can be easily handled by one operator.
