PACKAGING INSTALLATION AND METHOD FOR PRODUCING A PACKAGING UNIT, AND ALSO A PACKAGING UNIT MADE OF PACKAGING SLEEVES AND EXTERNAL PACKAGING

摘要

The document illustrates and describes a packaging installation and a method for producing a packaging unit (11, 11') from a packaging-sleeve group (2), which has a multiplicity of folded-flat, in particular upright, packaging sleeves (P), and external packaging. In order to cut back on costs for the material of the external packaging and to reduce, or as far as possible even to prevent, dust created by the external packaging during unpacking, and to reduce the amount of waste produced by the external packaging, provision is made for the packaging installation to have at least one conveying unit (3) for conveying the packaging-sleeve group (2) in a conveying direction perpendicular to the longitudinal extent of the packaging-sleeve group (2), and also to have at least one external-packaging unit (7), by means of which a web material (5), which forms the external packaging, is supplied in a basic position, and for a sealing unit (18) for sealing the web material (5), which encloses the packaging-sleeve group (2), to be arranged downstream of the web material (5) in the basic position, as seen in the conveying direction. This takes place by way of the following steps: - the packaging-sleeve group (2) is supplied, - a web material (5) is opened out in a basic position, - the packaging-sleeve group (2) is conveyed, in a conveying direction perpendicular to the longitudinal extent of the packaging-sleeve group (2), through the opened-out web material (5), wherein the web material (5) is pre-stressed, - the packaging-sleeve group (2) passes through a sealing unit (18) arranged downstream of the web material (5) in the basic position, as seen in the conveying direction, - the web material (5) is sealed by means of the sealing unit (18), and - the sealed web material (5) is severed in a sealed region (24).
