Innovations From Rieter Enable Increased Production, Improved Quality
According to Rieter, the compact, energy-efficient CLEANline blowroom offers an output of 1,200 kilograms per hour. Fine cleaning takes place in the card chute using CLEANfeed at several positions, each of which processes lower volumes of fiber, thereby reducing stress on the fibers. Other components contributing to improved yarn quality include the UNIfloc A 11 bale opener, UNIclean B 12 precleaner, VARIOset control system, UNImix B 75 blending machine and UNIstore A 78 feed and storage system.
Improving on productivity of earlier BT models, Rieter’s BT 923 rotor-spinning machine features a new design with 360 spinning positions per machine and rotor speeds of up to 110,000 revolutions per minute. Other upgrades include a winding device that enables delivery speeds of up to 200 m/min, and a 230-millimeter pitch that allows the use of up to 18-inch sliver cans.
