Fabric holding section assembly for holding fabrics constituting e.g. insulating layers, has three holding sections, where protrusion of one of holding sections is slid in groove of another holding section to obtain three-stage section

摘要

The assembly has three fabric holding sections including slot groove stages for holding and maintaining fabrics, and T-shaped extending protrusions (T) arranged in symmetry with corresponding supporting slot grooves (A), where the section is obtained by extrusion of metal alloy/plastic material. The protrusion of the first holding section is slid in the groove of the second holding section to obtain a two-stage fabric holding section. The protrusion of the second holding section is slid in the groove of the third holding section to obtain a three-stage fabric holding section.
