Tuftingkopf RS 522

Tufting of composites

The tufting head is forming a seam with a single thread method by one needle. This needle penetrates the material and inserts the thread forming a loop at the lower end of the needle position. The loop can be placed either within or outside the material. The tufting head works on 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.


    Designed for production of sub-preforms and preforms. Typical fields of application are aerospace, automotive, wind energy, bridge building or industrial lightweight construction.
