Abstract: The invention relates to a method, in a filling machine, of producing a package with a top of plastic which is injection molded in the machine and is capped before the top has become configurationally stable. In the method, the capping, at least during a first introductory phase, takes place in that a cap with internal threads is rotated and the package is displaced linearly in a direction towards the cap in such a manner that it may be ensured that the relationship between the speed of rotation of the cap and the speed of displacement of the package substantially correspond to the thread pitch of the threads in the cap and in corresponding threads on the neck when the threads enter into mesh with one another.

Abstract: The disclosure relates to an apparatus for sealing a package. The apparatus comprises a sealing unit and an abutment between which a number of material layers are disposed to be clamped and sealed and fused together, wherein the abutment is connected to at least one elongate element which extends in a direction from the abutment towards and past the sealing unit, the elongate elements, beyond the sealing unit are disposed to be connected to at least one first operating element, and an operating unit is disposed to apply a force between the sealing unit and the first operating element so that these are moved in a direction away from one another and so that the abutment and the sealing unit are moved in a direction towards one another.

Abstract: The disclosure relates to an apparatus for sealing a package, comprising a sealing unit (5b) and an abutment (6) between which a number of material layers (10) are disposed to be clamped and sealed and fused together, characterised in that the abutment (6) is connected to at least one elongate element (14c) which extends in a direction from the abutment (6) towards and past the sealing unit (5b), that the elongate elements (14c), beyond the sealing unit (5b) are disposed to be connected to at least one first operating element (13), and that an operating unit is disposed to apply a force between the sealing unit (5b) and said first operating element (13) so that these are moved in a direction away from one another and so that the abutment (6) and the sealing unit (5b) are moved in a direction towards one another.

Abstract: The disclosure relates to a method of producing crease-lined packaging material with a high degree of accuracy as regards the placing and forming of longitudinal crease lines. A web-shaped starting material (1) is provided, in connection with the laminate production, with a pattern of crease lines (6) extending at an angle to the longitudinal direction of the web, whereafter the material is divided into part webs (9). In connection with the conversion of each part web (9) into individual packaging containers in a filling machine, each part web is provided with complementary, longitudinal crease lines (17, 18).
