Laser-based metrology in the textile industry (spinning machines) - 2

API Application Story TM Laser-based metrology for ring spinning machines Picture: Rieter AG When 3D-metrology in the textile industry Machines Grow Laser-based Formulated very simply, many of the measurements carried out on the spinning machines of Rieter in Winterthur are concerned with the question of how long they are – because here, and in the other distance measurements in the machines themselves, we are dealing with fractions of millimetres under certain circumstances. Conventional measurement machines can be ruled out with machine lengths of 70 metres and more, even if they were...

API Application Story TM Laser-based metrology for ring spinning machines They not only measure the positions of the spinning locations, but also the rails on which the robots themselves hang. The tendency of the machines to expand in the linear direction must also be taken into account when choosing the fixed points on the floor for the set-up of the laser trackers. The automatic changing of the reels – with up to 1,632 yarn carriers being changed simultaneously in the largest machines – is also clearly dependent on the precision achieved when instal-ling the machine; in order to do this,...

API Application Story TM Laser-based metrology for ring spinning machines The RADIAN laser tracker from API used by Rieter is designed for measurement distances of 80 metres, and must also be able to work reliably in this range under unfavourable conditions. Its use on the narrow confines between the spinning machined also had to be tested. The final selection of the machine from amongst various potential providers took place within the context of an extensive test procedure at Rieter in Ingolstadt. Mobiles measurement in assembly Systems that are linked together, such as ring spinning...

Laser-based metrology in the textile industry (spinning machines) - 5

Laser-based metrology for ring spinning machines Increasing globalisation has now led to the fact that, in the meantime, spinning machines from Winterthur are now being produced locally on a worldwide basis, such as in China or India; these machines are then sold throughout the world. The latest innovations include, for example, compact spinning. These are generally more complicated machines with even more mechanical parts. They create yarns that have fewer hairs, which is equivalent to less flight (lint). Even finer shirts can be produced from them, as an example. The new air-jet...
