Method for forming a retention device, wherein a moulding device (1, 61) is provided which comprises a plurality of cavities (13, 64) which define gripping elements, a moulding material is distributed over an external face of the moulding device (1, 61) by a means for distributing material (3), which means is arranged opposite the moulding device (1), the step of distributing the moulding material being carried out so as to fill the cavities (13) with moulding material in order to form a tape (100) comprising a base (51) and elements or preforms which project from a first face of the base (51), a surface treatment is applied, for example a plasma treatment, more particularly plasma treatment at atmospheric pressure, to a second face of the base (51) opposite the first face of the base (51), the elements being held in the cavities (13, 64). |
