Method of manufacturing a foil tape and foil tape

A method of manufacturing a foil tape for sealing joints between two structural elements, for example in house-building between masonry and a door or window jamb, the method comprising the steps of:

• a) providing a tape-like membrane or cutting the membrane to size;
• b) providing a tape-like textile or cutting the textile to size;
• c) joining the textile to a top side or underside of the membrane;
• d) applying an adhesive layer to at least certain areas of that side of the membrane which is averted from the textile;
• e) folding the foil tape along a longitudinal axis to form a folded body, so that the adhesive layer forms in certain areas an outside of the folded body on a top side and/or an underside of the folded body and sections of the textile lie on top of one another in the interior of the folded body at least in certain areas;
• f) joining the sections of the textile lying on top of one another in certain areas, so that the sections of the textile lying on top of one another are joined partially and in particular in a punctiform pattern.
