Assembly for marking faults on moving materials

摘要

The system to mark objects, to indicate fault locations, has a fault signal trigger from a detector to operate a following marker with a pyrotechnic propellant to deliver a marking material timed accurately to the fault site. Also claimed is an assembly with at least one cartridge (5) magazine (7) with at least one ignition (4) at a gap after the detector (2) in the direction of object (1) travel. Each cartridge (5) has a pyrotechnic propellant and a marking material. The detector (2) is electrically connected to the ignition (4) through an amplifier and a variable signal delay unit (3).
