Rieter Develops Combing Prep Machine, Offers R 40 With Three Robots

Switzerland-based Rieter Textile Systems' Spun Yarn Systems division has improved upon its Unilap combing preparation system with the development of the new Omegalap E 35.

The new machine features a patented belt lapping system that enables lap contact pressure to be distributed over more surface area than is achieved with the Unilap. The lap guidance and pressure on the lap’s circumference can now be distributed over 180º at the beginning of the lap and 270º at the end, resulting in constant lap speeds of up to 180 meters per minute and production of 500 kilograms per hour for a 40-percent production increase including can and lap changing times. High lapping speeds can be achieved with any staple length.

The Omegalap E 35 provides uniform quality and improved mass regularity, according to Rieter. Other features include an easily replaceable lap-winding belt, which offers a production performance of 1,000 tons per belt.

As part of a Rieter combing set — which also includes three SB-D 40 pre-draw frames, six E 66 combers or E 76 Robolap combers, and three RSB-D 40 draw frames — the Omegalap E 35 increases production capacity to more than 10 tons of yarn per day, the amount required to produce 40,000 high-quality shirts.

In other company news, Rieter now offers very long R 40 rotor spinning machines with three robots for the production of medium- and fine-count yarns. Two robots are located on either side of the machine, while the third changes sides via the short loop as programmed by the controller, who can set operating ranges for each robot at the central machine control unit. Each robot has its own maintenance position. Maintenance work on the robots is conducted ergonomically on the loop without interfering with other operations.
