Abstract
The casting-mould pattern (3) has a shaft-like cutout (3a). The surface of the pattern, including the cutout (3a), is intended to be lined, in a finishing manner, with a single plastic sheet (5), without destroying the same. First of all, an opening, extending through the pattern (3), is produced and, therein, there is arranged a body (4) which is designed such that it corresponds in cross-section with the opening and can be displaced between a raised and a lowered position in which the body forms the base of the cutout in the pattern. When the body (4) in the cutout (3a) is in its raised position, a plastic sheet (5) is then made to adhere to the surface of the pattern and of the body (4), and said body is then pushed downwards into the lowered position. In this arrangement, the body takes that part of the plastic sheet which covers it along into the lowered position, with the result that a cutout (3a) lined by the plastic sheet is formed on the pattern (3). <IMAGE>
