- Title
Rieter: twisting of artificial grass yarns.
- Abstract
The article reports on the launch of DT 660 RTFIEM line of yarn twisting machines from Rieter Filament Yarn Technologies in May 2004. Polypropylene (PP) and polyethylene (PE) tape yarns are twisted because they cannot be used directly after extrusion. Twisting gives the yarn a curl that is then accentuated by knitting or unknitting. The result is a yarn that remains straight in the mat with an appearance similar to grass. At present, the tendency is to try to produce 15,000 dtex yarns. In sports where the players often fall, the industry use PE yarns, while for field hockey, they use PP yarns. The twisting machines developed by Rieter are modular which allows the testing and adjustment of factory settings before shipping. The twisting machines also reduce assembly and start-up time for the customers. To be able to work according to the twist rate at take-off speeds of 200 to 300 meters per minute, a new high-speed take-up system was developed that consists primarily of: a new column bobbin changer with a device that avoids bobbin vibration and that has pneumatic handling assistance; a new individual more robust reciprocating motion and a new design; and a new individual motorization of the capstan and of the starting roll.
