<p>An injection moulding device comprises an internal tool (2) and a partible external tool (3) which is transformable from an open state to a closed state and vice versa. The tools are capable of fastening an edge of a sleeve (6), of a packaging material, between them when the external tool (3) is closed, in order to injection mould a plastic part onto said sleeve (6) between said internal tool (2) and said external tool (3). At least one gripping portion (4) of the inside of the external tool (3) is reciprocatingly slidable from a first position to a second position. The gripping portion (4) is in the first position arranged to effect a circumferential enclosure of the sleeve (6), leaving a radial clearance (8) around the sleeve (6), and in the second position arranged to effect an essentially complete enclosure of the sleeve (6), eliminating said clearance (8).</p> |
