Injection-moulded article comprising a field of hooks obtained by moulding

A method for manufacturing by moulding of a moulded article comprising a field of hooks obtained integrally with part of an outer surface of the molded article, said method comprising the steps of

• providing a moulding device which comprises an inner closed surface which defines a main moulding chamber, at least one introduction opening for introducing thermoplastic moulding material into the moulding chamber, a field of cavities with a form complementary to hooks opening onto a first part of the inner surface, the first part of the inner surface being surrounded by an edge surface which does not comprise a cavity, and thrust means for thrusting at least a portion of the edge surface and an opposite part of the inner surface towards one another, the arrangement being such that the thrusting by the thrust means is limited, such that the edge surface and the opposite part which are thrust towards one another cannot come into complete contact with one another, a gap being thus formed between the edge surface and the opposite part, the gap being dimensioned so that the moulding material cannot penetrate into the gap unless a pressure corresponding to a pressure which prevails when substantially all of the chamber filled with moulding material is applied to the gap, and
• injecting thermoplastic material through said introduction opening, in a single step of introduction.
