ABSTRACT:
A mould portion and/or protective element of the type consisting of a material subjected to deformation is disclosed. A method and a device for manufacturing such a mould portion and/or protective element are also disclosed.
The mould portion and/or protective element is preferably 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 during transportation and storage thereof.
Such materials subjected to dimensional changes as can be used as mould portions and/or protective elements present the advantages of being inexpensive and permitting removal of the article without difficulty. One such material is for example cellular plastics. The dimensional changes, however, have entailed so great difficulties in using mould portions 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 portion and/or protective element of a material subjected to dimensional changes is manufactured with the desired dimensions, starting from at least one blank, immediately before the mould portion and/or protective element is used to mould the article or join the mould portion and/or protective element to the article to protect the surface portion thereof. Alternatively, the mould portion and/or protective element of a material subjected to dimensional changes is manufactured with the desired dimensions, starting from at least one blank after the blank has reached dimensional stability.
