Spindles in modern ring spinning machines reach speeds of up to 25,000 rpm. In these high-speed applications energy consumption is an important issue. Novibra is now introducing the new LENA (Low Energy consumption and Noise Absorption) high-speed spindles. LENA design has been developed from well-proven Noise Absorbing System Assembly (NASA), which ensures minimum neck bearing load, vibration and noise level at high speed. The unique wharve diameter of 17,5 mm and the footstep bearing diameter of 3 mm lead to a lower energy consumption. LENA is designed for tube lengths up to 200-210 mm.
Another new product presented at ITME is the clamping and cutting crown CROCOdoff, which is also available as the version CROCOdoff Forte for coarse yarns. The crown is operated by the spindle speed and has been designed for machines with autodoffer. The improved design of the “teeth” guarantees a reliable clamping and cutting of the yarn. In addition, the CROCOdoff reduces the risk of yarn breakage during start-up, decreases energy consumption, minimises material loss and reduces maintenance. CROCOdoff is suitable for the use with new machines as well as an upgrade for existing machines.
