The right spindle to make the difference

Spindles are at the core of spinning machines and play a crucial role in their performance. With an impact on productivity, quality, energy saving, or work environment, selecting the right spindle for an application is key. Thanks to Novibra’s wide range of spindles, finding the perfect spindle is child’s play.

As the leader in spindle technology, Novibra offers a great selection of innovative and high-performance spindles.

First-ever spindle to run at 30 000 rpm – NASA HPS 68

Famous for extending service periods, reducing noise levels, and ensuring maximum durability, Novibra’s flagship and best-seller NASA HPS 68, already convinced premium machine manufacturers such as Rieter, Toyota, or top-class Chinese producers.

Installations in the optimum range for NASA HPS 68 – at medium to fine yarn counts and 20 000 to 30 000 rpm speed – represent a completely different type of load on the spindle than coarse yarn count applications. Smaller repeated loads at high frequencies occur causing micro-vibrations. Therefore, a chamber filled with lifetime grease was introduced as a second damping system. Noise is thus significantly reduced, making the spinning mill a better place to work.

Reliable solution for medium and fine yarn counts – HPS 68

Novibra’s second best-selling spindle, HPS 68, has been a technical revolution in the switch from conical types to spindles with a flat tip. Its unrivaled spindle insert constitutes a base for all Novibra spindles of younger generations. HPS 68 is the right spindle to spin standard short-staple fibers to medium and fine yarn counts.

Although higher speeds are possible, the spindle outperforms at speeds up to 20 000 rpm with favorable noise levels and a long lifetime.

The right choice for coarse yarn counts – L HPS 68

When spinning coarse yarn counts, L HPS 68 is the right spindle. Its unique wharves diameter of 18.5 mm ensures optimized energy consumption and load on the machine driving elements. In most applications, a full cop and high tension of the yarn put a heavy load on the spindle neck bearing – which is increased by further imbalances occurring in the spinning process of coarse yarns. The special design elements of the L HPS 68 spindle absorb heavy loads and ensure the desired harder damping.

The spindle mostly runs with tube lengths from 220 to 250 mm, but it can also be operated with tube lengths of 280 mm, e.g. by wool spinners. While speed increases up to 20000 rpm are an option, the speed is limited by the desired yarn count and twist.

High speed and energy savings – LENA

The latest addition to the Novibra spindle family was specially designed to achieve high speeds with the lowest energy consumption and reduced noise.

LENA is the right spindle to spin yarn counts of Ne 30 and finer, with tube lengths up to 210 mm at speeds up to 30 000 rpm. Thanks to the uniquely small wharve diameter of 17.5 mm, 4 to 6% energy savings can be achieved. As creating a more sustainable future for the textile industry is getting more and more urgent, LENA is an attractive choice.

The right crown for every spindle

Based on the machine type, doffing system, and raw material or yarn count, with only one goal in mind: boosting customer’s competitiveness, Novibra offers countless designs from replaceable EASYdoff to sturdy steel crowns and from SERVOgrip to self-cleaning CROCOdoff.

The wide range of Novibra spindles covers any requirement.

Novibra also provides customized spindles without catching crowns for machines without automatic doffers.

However, only optimally selected spindles to give the best results. Yarn count, speed, lifetime, maintenance, or energy consumption requirements must be considered in the selection process. Novibra sales teams assist customers in choosing the right spindle to achieve the optimum performance.
