Abstract
A method for manufacturing moulded flexible plastic skins (9, 24, 27, 34) differing in their shape from each other, each skin being moulded against a mould surface (2) of a mould (1), comprises the steps:—providing a mould surface (2) matching the shape of the skin to be moulded by using a first mould surface provided by the mould itself or by altering the first mould surface by placing one or more mould inserts covering only a part of the first mould surface onto said mould surface and thereby providing an alternative second mould surface,—applying a plastic compound to be brought to shape by the mould surface (2) provided,—bringing to shape the plastic compound applied to the mould surface (2), and—demoulding the moulded skin (9) from the effective mould surface (2). The at least one mould insert (7) used is flexible, whereas a mould insert (7) is arranged on the first mould surface in that the side surfaces of the insert adjoining its own mould surface abut against a wall of the first mould surface arranged angular to the adjacent mould surface, in particular an upstanding wall at least in those sections of the insert used for shaping the plastic compound. A mould arrangement for moulding flexible plastic skins (9) differing in their shape from each other, each skin moulded against a mould surface of a mould, the arrangement comprises a base mould with a first mould surface and one or more mould inserts to be arranged on the first mould surface and covering only a part of the first mould surface. The at least one mould insert is flexible nature and the first mould surface carries one or more walls arranged angular to the adjacent mould surface, in particular upstanding from its first mould surface and the mould inserts abut with their side surfaces adjoining their own mould surfaces against such wall at least in those sections of the insert used for shaping the plastic compound.

15. A method for manufacturing a moulded flexible plastic skin and variants thereof, which flexible plastic skins differ in their shape from each other, comprising the steps:
-
providing an effective mould surface matching the shape of the skin to be moulded by either using a first mould surface to manufacture a skin in a first shape, said first mould surface provided by the base mould or by using a second mould surface to manufacture a skin in a second shape, said second mould surface provided by placing one or more mould inserts onto the first mould surface, said insert covering only a part of the first mould surface, each insert providing a mould surface as part of the effective mould surface, and thereby providing an alternative second mould surface; applying a plastic compound to be moulded on said effective mould surface provided; bringing to shape the plastic compound applied to the effective mould surface, demoulding the moulded skin from the effective mould surface, and wherein that the at least one mould insert used is flexible, whereas such mould insert is arranged on the first mould surface in that the side surfaces of the insert adjoining its own mould surface abut against a wall of the first mould surface arranged angular to the adjacent first mould surface, in particular an upstanding wall at least in those sections of the insert used for shaping the plastic compound. - View Dependent Claims (17, 18)

26. A mould arrangement for moulding a flexible plastic skin and variants thereof, which flexible plastic skins differ in their shape from each other the arrangement comprising:
-
a base mould with a first mould surface for manufacturing a skin in a first shape; one or more mould inserts to be arranged on the first mould surface and covering only a part of the first mould surface and when applied to the first mould surface each insert providing a mould surface as part of the effective mould surface thus defining a mould with an alternative effective mould surface for manufacturing a skin in a second shape; wherein the at least one mould insert is flexible; and the first mould surface carries one or more walls arranged angular to the adjacent mould surface, in particular upstanding from its first mould surface and the mould inserts abut with their side surfaces adjoining their own mould surfaces against such wall at least in those sections of the insert used for shaping the plastic compound. - View Dependent Claims (27, 28, 29)
