Reinforcing system


The fabric-covered metal spiral is inserted inside the duct; it maintains permanently its cylindrical shape and keeps the fabric stretched. The necessary lead of the spring is provided by longitudinal textile strips. Five-metre long Helix sections are connected to zip fasteners attaching separate sections of the ducting together. The spiral can be easily removed for maintenance purposes; its manufacturing design is suitable for a majority of shaped pieces. The necessary tension of the fabric will be achieved by the tensioners in profile and in blanking.
