Connecting composites
A single thread chain stitch seam is formed with only one single needle thread, which is brought into the material by two needles from the top side of the material. The two needle head connects virtually all composites (carbon fibres, glass fibres, aramid), such as profile or stringer, even complex 3D-parts.
Tool changer:
The tool changer allows fast and easy interchanging of different end effectors as well as electrical and pneumatical interfaces for specific signals at one robot stitching system.
One tool changer is required at the robot and one at each end effector.
Application
Designed for production of sub-preforms and preforms. Typical fields of application are aerospace, automotive, wind energy, bridge building or industrial lightweight construction.
