Abstract
The flexible tube used as a duct for dust extraction or ventilation consists of two layers of material (3, 4) with a helical reinforcement (2) between them. The two layers are preferably of aluminium foil or may be of plastics sheet, and the reinforcement is circular section wire. The two layers may be welded together, or adhesive may be used. The wire may be incorporated so that it appears as a bulge inside the composite tube or outside, but still retained between the layers. One or both layers may be of a multilayered material.
