Method for forming a container blank from pulp material using a mould, said blank comprising walls and a bottom. The object is for the end container product to have relatively straight walls. Since in the moulding of paper pulp a certain tapering of the walls during their moulding is necessary to maintain clearance of the mould, provision is made according to the invention for a container blank with relatively inward slanting walls and with an in some way curved bottom to be made first, following which the curve is removed from the bottom when the walls are moved apart, so that a container with straight walls is produced. <IMAGE> |
