| 摘要 |
A method of moulding an article having a relatively small thickness in relation to its dimensions in plan including providing a mould for the article, locating or forming one or more inserts on a mould face which will define a part of the surface of the moulded article, introducing the material to be moulded into the mould, providing attachment means with an irregular surface in contact with the material, maintaining the mould in such an orientation while the material hardens and mechanically bonds to the attachment means, such that the said mould face is inclined to the horizontal at an angle at which the or each insert is retained on the said face against slipping by friction during the hardening of the material, and providing gas-outlet means from an upper part of the mould in the said orientation to allow the escape of gases during the moulding process. The attachment means is treated on one face or provided with knit loops so as to adhere to the material of the article during curing.
