Abstract
An apparatus for packaging groups of contains of liquid products into bundles includes at least one pair of wrapping stations of groups of containers. Each station is configured to wrap an extensible film around a group of containers and to feed and discharge the groups of containers to/from the wrapping station and includes at least one feeding line of the containers and at least one discharge line of the bundles. Advantageously, the feeding and discharge lines are shared between different wrapping stations.

Apparatus for packaging containers for liquids into bundles, comprising:
- at least one pair of wrapping stations for groups of containers, each station in turn comprising means for wrapping an extensible film around a group of containers and manipulating means for feeding and discharging said groups of containers to/from the wrapping station;
- at least one feeding line of the containers to be packaged;
- at least one discharging line of the containers packaged into bundles;
- wherein a feeding line is intermediate with respect to the wrapping stations of each pair of wrapping stations and wherein there are at least two discharge lines, each of which is opposite said feeding line with respect to the corresponding wrapping station or, vice-versa, a discharge line is intermediate with respect to the wrapping stations of each pair of wrapping stations and wherein there are at least two feeding lines, each of which is opposite said discharge line with respect to the corresponding wrapping station.
Apparatus for packaging containers for liquids, comprising at least one station for wrapping groups of containers in bundles, the station in turn comprising:
- a gripping group comprising at least two U-shaped jaws, able to move one against the other along a longitudinal axis to laterally clamp a group of containers and hold them vertically without engaging an upper portion and lower portion thereof;
- means for wrapping an extensible film around the group of containers held by the gripping group, a wrapping direction of the film being circumferential with respect to the longitudinal axis of the gripping group;
- and
- an element for cutting the film, able to move parallel to the longitudinal axis of the gripping group, near to a lower perimeter of the bundle in formation, to separate the part of the film wound on the bundle of containers from a remaining part of film.
Process for packaging groups of containers for liquids, comprising the steps of:
- a) forming a group of containers having a longitudinal axis;
- b) wrapping said group of containers around an axis with a film of non-heat-shrinking extensible plastic material;
- c) locking said film at a bundle in formation;
- d) cutting the film to separate a portion wound on the bundle from a remaining part,
- wherein cutting the film is carried out with a cutting element able to move alternately in a direction parallel to said axis.
