Apparatus and method for securing a substrate to a plastic strip, and fastening device likely to be obtained by said method

A method for assembling an assembly comprising a tape of retaining elements and a substrate, said method comprising the following steps:

• a step of forming a tape of retaining elements by dispensing a molding material into a molding device, so as to form a tape of retaining elements comprising a base presenting a bottom face and a top face, the top face of the base being provided with retaining elements;
• and
• a step of applying a substrate against the bottom face of the base following the step of forming the tape and prior to said bottom face of the base solidifying in such a manner as to cause the substrate to penetrate at least in part beyond a plane defined by the bottom face of the base of the tape;
• wherein the substrate is applied against the bottom face of the base of the tape of retaining elements downstream from a location where the tape of retaining elements is formed with molding material dispenser means that form the tape and prior to said bottom face of the base solidifying,
• wherein the molding device is a molding strip and the base of the tape is free from any increased thickness extending continuously along edges of the base of the tape.
