Filament Winding Experts from Roth Composite Machinery’s Present at JEC World

Filament winding experts presented at the leading trade fair JEC World in April

The filament winding experts from Roth Composite Machinery traveled to Paris for JEC World to present an innovative automation concept for reliable fiber changes as well as the new special winding software “µRoWin.” The composites industry event was held April 25-27, 2023 and Roth Composite Machinery attended with an international team of experts from Germany, the U.S., Korea and China and presented its service portfolio as well as its latest innovations.

Fast and safe fiber change

The new splicing unit, which emerged from the company’s own development work and proves to be very powerful in the trial phase, is likely to be a particular eye-catcher. This is an innovative automation concept in which compressed air is used to swirl the individual fibers for all fiber strands in parallel to create a secure connection with the changeable fibers. Until now, the rovings have either been knotted or spliced by hand when they are changed – a process that is not only time-consuming but also prone to errors. The automated process, together with the corresponding machine, can execute the fiber-changing process quickly and safely.

Special software optimizes simulation and process

Automation, safety and time-saving were highlighted for the new winding software µRoWin at JEC World. The software solution for generating programs for the machine movement has been specially adapted to the high-level filament winding machines of Roth Composite Machinery. It offers a fluent workflow and allows all relevant input parameters to be checked at any time. The transparency and precision of the algorithms anchored in the software ensures the highest placement accuracy of the fibers – and is thus an important instrument for quality assurance.

The powerful and user-friendly special software not only optimizes the winding process but also ensures maximum efficiency beforehand: the structure can be designed and optimized via 3D simulation. This “digital twin” can then be transferred to the machine as a control code simply by pressing a button.
