Blindstitch head RS 510

Stitching on a solid tool

The blindstitch seam is formed with only one single needle thread, which is brought into the material by one curved needle from the top side of the material. The blindstitch head connects virtually all composites (carbon fibres, glass fibres,  aramid), from profile or stringer to complex 3D-parts.

Advantages for the user:

  • Bottom thread not required
  • Access to the work piece from one side only
  • Variably adjustable penetration depth
  • Stitching with firm pad possible

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.
