摘要： The invention describes an apparatus for the integral injection molding of a synthetic plastic top on a paper tube with an overall injection molding unit with a nozzle, a driven extruder worm (4), plasticising cylinder and a synthetic plastics injection unit, the nozzle being connected to the plasticising cylinder and being enclosed at least partially and externally by two movable outer mold parts, the inner mold part consisting of a movable mandrel.To reduce the technical complication while at the same time satisfying more fully the hygiene demands imposed on such machines, particularly in the foodstuffs sector, it is according to the invention suggested that the plasticising cylinder and the nozzle be stationary in their mountings on the machine frame and that the extruder worm be driven by an electric motor and that the synthetic plastics injection device comprise a two-armed lever which is driven and which is subject to the action of a control force unit and which is in contact with the extruder worm adapted for movement in the direction of its longitudinal axis.

摘要： 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.
