Function
- Joining of separate parts of subpreforms (e.g. stringers and skin) into a single preform using blindstitching
- Single-sided transversal stitching of complex multilayer preforms along curvilinear path to form folding lines
- Stitching complex preforms to compact layers and achieve given thickness
- Joining separate parts of subpreforms (e.g. stringers and skin) into a single preform
Blindstitch principle
Making a stitch using one thread and bent needle at a one-sided access, the needle doesn’t penetrate base material.
