A collapsible barrier comprising at least one rail (2) and a secondary rail (10').

a wing stringer or chord member

The co-cured composite stringer includes a stringer and a mandrel positioned within a channel defined in the stringer.

The interconnection (1) has a T stringer (9), an Ω stringer (10) and a connecting arrangement (2).

In order to displace a heald in a Jacquard-weaving machine, a heald spring is used for producing a tension force acting on the heald.

This provides a coupling of an Ω stringer to a T stringer which is comparatively insensitive with respect to tolerances relating to the orientation of the Ω stringer (10) in relation to the T stringer (9).

The inventive method is characterised in that a warp thread (I) guiding a filling yarn (1) co-operates with a longitudinal heddle (01) connected to the filling yarn and is arranged between said filling yarn and the stop bar of the weaving loom.

The invention relates to a rail (2) which designs this structure (1).

The invention also relates to a calender that makes use of the method.

A reinforced composite structure for an aircraft comprises a fiber reinforced composite stringer.

Such a warp presents the advantages of a metallic warp with regards to the wear of the ring and the advantages of a non metallic warp with regards to its light weight.

The present invention provides a casing structure of low weight provided with a laminate stringer of high rigidity.

A multi layer composite L-shaped stringer (2) for use in an aerospace structure comprises a foot(6) and a web (8) extending from an edge of the foot.

The first list element is a profile list (5) which has a section open towards a support surface (2) and intended for receiving a second list element (6).
