ABSTRACT:
Described is an apparatus for injection moulding a cover on to a plastics-coated tubular paper case (2), the apparatus including an injection-moulding core (4) and an outer mould embracing same. So that, in the case of a paper tube (2) of quadrangular cross-section, the flat walls of the tube do not suffer deflection and the location at which the cover is injection-moulded on to the tube is reliably controlled, it is provided in accordance with the invention that at least one support portion (6) is mounted on the edge face (10) in outstanding relationship beside the straight upper outer edge (11) of the injection-moulding core (4), against which support portion the edge of the paper tube (2) can be brought to bear.
