| 摘要 |
According to the invention, a thermoplastic supply material, in solid form, is continuously conveyed into a heating and spreading iron (shoe) 1, the material being progressively softened in the iron (shoe) and conveyed, in liquid form, beneath the iron (shoe) in order to be successively distributed, compressed and spread out over the running sole 12 of the ski, and then forced under pressure by a transverse doctor (scraper) blade 14 attached to the spreading iron (shoe) 1. The doctor (scraper) blade 14 is a steel bar of rectangular cross-section, the lower edge 16 of which projects slightly beneath the lower face 8 of the spreading iron (shoe) 1. The projection of the lower edge, the inclination of its front face, the speed of movement and the pressing force are chosen suitably. <IMAGE>
