<p>The seal comprises at least one sealing lip provided with an edging or covering facilitating the sliding and supported by the body of the slide. The sealing lips (61, 62) of the slide are formed by extrusion. On them is deposited a sliding covering (65, 66), either by coextrusion of an appropriate material, or by flock coating or by a combination of coextrusion and flock coating. The said lips are arranged in an injection mould of shape corresponding to that of the slide to be manufactured and into the said mould is injected the elastomer or plastomer material intended for forming the body of the slide and thus firmly attached, by the same moulding, to the said sealing lips. <IMAGE></p> |
