PCT No. PCT/BE94/00037 Sec. 371 Date Mar. 17, 1997 Sec. 102(e) Date Mar. 17, 1997 PCT Filed Jun. 1, 1994 PCT Pub. No. WO95/32850 PCT Pub. Date Dec. 7, 1995In the method according to the invention, as shown in the drawings, the elastomeric skin is manufactured in a mold assembly having a mold surface (2), a portion (3) of which is shielded off by means of a mask (4), a first elastomeric material (7) is sprayed on this mold surface (2), the mask (4) is removed, and a second elastomeric material (9) is sprayed on said portion (3) of the mold surface (2). The edges (11) of the mask (4) are placed on top of upstanding edges (13) of the mold surface (2) so that the transition between both elastomeric materials (7, 9) is achieved on these upstanding edges (13), i.e. in an outer recess of the elastomeric skin resulting in an aesthetic visual parting line. According to a further important aspect, the edges (11) of the mask (4) are maintained at a distance from the mold surface (2) such as to avoid contact between the layer of first elastomeric material (7) sprayed onto the mold surface (2) and the mask (4).
