A sealing, trimming or finishing strip, for use in vehicle body construction for example, comprises two strip members (5,6) such as made by extrusion from vulcanised rubber which are joined together by a corner piece (8) produced by an over-moulding process. The over-moulding process is a bi-injection process. It produces relatively hard thin layers (10,12) of thermoplastic elastomer which respectively form interfaces with the vulcanised rubber of the two strip members (5,6). Relatively soft thermoplastic elastomer material (14) is positioned between and interconnects the relatively hard layers (10,12). By ensuring that the only interfaces are between (a) between the vulcanised rubber of the strip-like members (5,6) and the relatively hard thin layers (10,12), and (b) between the relatively hard layers (10,12) and the relatively soft material (14), risk of subsequent rupture between the strip-like members (5,6) and the overmoulded part (8) is reduced. <IMAGE> |
