ABSTRACT OF THE DISCLOSURE A mould part and/or protective element of the type made of a material subject to deformation is disclosed. A method and a device for manufacturing such a mould part and/or protecting element are also disclosed. The mould part and/or protective element is particularly intended to be used as a mould portion in moulding an article and/or as a protective element to prevent access of soil and water to a surface portion of the article dur- ing transportation and storage thereof. Such materials subjected to dimensional changes as can be used as mould parts and/or pro- tective elements present the advantages of being inexpensive and permitting removal of the article without difficulty. One such material is for example cellular plaslics. The dimensional changes, however, have entailed so great difficulties in using mould parts and/or protective elements of such materials that they have made the use of the material impossible. To eliminate the above-mentioned disadvantage the mould part and/or protective element of a material subjected to dimensional changes is manu- factured with the desired dimensions, starting from a least one profile strip, immediately before the mould part and/or protec- tive element is used to mould the article or join the mould part and/or protective element to the article to protect the surface portion thereof. Alternatively, the mould part and/or protective element of a material subjected to dimensional changes is manu- factured with the desired dimensions, starting from at least one profile strip after the strip has reached dimensional sta- bility.
