Abstract:
A magnetic can-body standing-up apparatus (Z) comprises an inlet transporting device (10) for conveying lying can bodies (4), a transporting device (12) arranged above the inlet transporting device (10) for conveying upright can bodies (9) hanging on the transporting device (12), and a controller (13). A first magnet arrangement (1) which is activatable and deactivatable in a manner controllable by the controller (13) is arranged below the inlet transporting device (10) in such a manner that a can body (4) lying on the inlet transporting device (10) is magnetically securable in a releasable manner on the inlet transporting device (10). A second magnet arrangement (2) is arranged above a region of the inlet transporting device (10) in which the can bodies are transported and is configured in such a manner that a can body (4) lying on the inlet transporting device (10) can be lifted up by means of the magnetic field of the second magnet arrangement (2) when the magnetic field of the first magnet arrangement (1) is deactivated. A third magnet arrangement (3) is provided above the transporting device (12) and is configured and arranged in such a manner that a can body (4a) which has been lifted up can be lifted up further and can be lifted off the inlet transporting device (10) and can be transported upright hanging magnetically on the transporting device (12). The controller (13) is configured in order to activate the first magnet arrangement (1) when a front edge of a can body (4) lying on the inlet transporting device (10) passes the second magnet arrangement (2) and in order to deactivate the first magnet arrangement (1) when a trailing edge of said can body (4) comes to lie under the second magnet arrangement (2).
Abstract:
A tear-off lid (10) has a removal opening (15) with a beaded rim and is designed such that prior to beading of the rim a plastic layer is applied to the collar of the lid ring in the form of a strip (32) of little thickness and preferably of less than 0.1 mm thickness. The invention thus allows in a cost-effective manner a good sealability of the cutting edge (31) of the tear-off lid and permits production thereof at high rates.
Abstract:
Ein Aufreissdeckel (10) umfasst einen umlaufenden Befestigungsabschnitt (6), einen Siegelflansch (7) mit einer auf diesem aufgesiegelten Aufreissfolie und einem um den Siegelflansch (7) umlaufenden eingerollten Rand (5), der die Entnahmeöffnung (15) seitlich begrenzt. Der eingerollte Rand weist eine bandförmige Dichtung (32) aus einem Kunststoff, insbesondere aus einem thermoplastischen Elastomer (TPE), auf, welche eine im Wesentlichen gleichmässige Dicke aufweist.
