Abstract

Flexible tubing made from overlapping spiral windings of impermeable tape and steel wires, has overlaps, which enclose the wires, bonded by application of a hot melt adhesive with a melting range of 12 degrees C. The melt adhesive is a plasticised polyamide which is molten at 142 degrees C and sets at 136 degrees C. It is esp. suitable for tubing made of non-flammable material such as glass cloth, covered on at least one face with a plastic, elastomeric or silicone coating or thin Al foil, pref. enclosed by a further layer of glass cloth etc., e.g. for ventilation or dust extraction ducts.
