Method for attaching an insert (18), at least partly composed of thermoplastic material, in an at least partly hollow body also composed mainly of thermoplastic material, which is produced in a mould (1) either by melting the thermoplastic material in the mould (1) or adding it to the mould in a readymolten state and, after having spread the molten thermoplastic material in a layer (33) over the inner walls of this mould (1) in the appropriate way, solidifying it or leaving it to solidify in order to subsequently remove the body of thermoplastic material thereby obtained from the mould, whereby, during a first stage, the insert (18) is positioned in the mould (1) at a specific distance from the still-molten thermoplastic material, ensuring that it suffers no substantial deformation as a result of the presence of this material and, at a second stage, while the thermoplastic material of which the hollow body is being moulded is solidifying, bringing the insert (18) into close contact with the thermoplastic material while it is still sufficiently soft, so that the latter can form substantially a whole with the insert (18) and, at a third stage, when the aforementioned material is almost solid, removing the body with the attachement insert (18) from the mould. |
