Force constant adaptation of braided sleeving in the automated production of braided components

01.04.2015

The Institute of Aircraft Design (IFB) at the University of Stuttgart developed a flexible pressure roll mechanism for braiding machines, which significantly improves the automated braiding of components with sharp curvatures and widely varying cross-sections without the need for manual intervention. While overbraiding a mandrel the flexible mounting of the pressure rolls allows for adaptation to the mandrel's positioning (e.g. inclined position) and to changes in the cross section. They exert a constant and precisely defined force on the braid and thereby press it against the mandrel. As part of the automated process, the robot control of the braiding machine coordinates the movement of the pressure rolls. This significantly improves the braiding of components with a variable cross-section and curvatures so that manual intervention is no longer required.
