Stiffening element for a narrow warning screen comprising a detecting wire

摘要

The mesh for an alarm grill has a detector wire with a plastics netting having longitudinal slots (3) and a metal detection wire (4) extending along a longitudinal direction. The wire is fixed to the netting by glue via an adhesive tape (5) which covers it at least locally. The wire also extends transversely in an undulating condition and is held by the tape to prevent bending of the wire.
