Machine for packaging paper rolls (R) comprising adhesivation means (EG) adapted for applying an adhesive substance (GG) on an internal side of a side flap of a packaging sheet, which adhesivation means act while the rolls (R) pass through an entry station (E) of the machine.

The present invention relates to the forming of a container by folding a cardboard sheet with at least vertical flaps, using a forming device and a forming method. Such a device comprises an upstream conveyor driving said cardboard sheet in a direction of travel, a downstream conveyor, means for folding the vertical flaps, said folding means being situated symmetrically about said upstream conveyor, and is characterized in that, on each side, said folding means comprise a pair of downstream and upstream pushers forming a gripper, said pushers being actuated jointly from an open position toward a closed position of folding said corresponding vertical flaps, a support for each gripper, said support being mobile in said direction of travel.

Systems and methods are disclosed for dynamic adhesive application for roll-formed containers. In one embodiment, an example system may include a first conveyor configured to convey a packaging material, and an adhesive application system configured to apply adhesive to the packaging material, the adhesive application system having an adhesive applicator configured to dispense adhesive, and an applicator support assembly configured to support the adhesive applicator. The adhesive support assembly may be configured to move the adhesive applicator in two dimensions, where the adhesive application system can apply adhesive along three edges of the packaging material.

Cartoning machine comprising: a store unit (M) for flat cartons or blanks (F); a blank feeding station (E); an unfolding station (SR) for forming boxes; a feeding station (A) and an insertion station (N) for the products to be packaged. At least two guide blades (202L, 202R) and folding members (206, 207) are arranged in the insertion station (N) for folding the side flaps (PSL, PSR) of the blanks inwards. The blades (202L, 202R) are connected to means which control their positioning in the open position and respectively in the closed position for disengaging the internal faces of said flaps (PSL, PSR). The blades are moved in such a way that, after inserting the products in a box, they are placed in the closed position and subsequently, while the box is moved towards the exit of the machine, they are placed again in the open position for a pre-established time.

A packaging device for packaging articles into boxes including a mandrel, a handling unit, a first retaining device, and a closing unit. The mandrel is adapted to be wrapped at least partially by panels of a blank to form a partially closed box. The handling unit is configured to move said mandrel along a feed trajectory. The first retaining device is configured to retain at least a first panel of the blank wrapped at least partially on the mandrel. The closing unit is arranged to at least partially overlap and fix an outer panel onto an inner panel of the blank. The closing unit includes a hitting element movable along a displacement trajectory between a rest position, wherein the hitting element is in a position far from the mandrel, and a pressure position, wherein the hitting element is in a position such to press the outer panel on the inner panel and against a second abutment surface of the mandrel, and a displacement member configured to displace the hitting element between the rest position and the pressure position.

A cartoner includes an entrance section, a loading section, an exit section, a transport system and a controller. The entrance section is configured for picking carton blanks from a magazine and folding a first side of the carton. The loading section is configured for loading a product into the first-side-folded carton. The exit section is configured for closing the loaded carton. The transport system is configured for transporting the first-side-folded carton from the entrance section to the loading section and the loaded carton from the loading section to the exit section. The controller is arranged for controlling an operation following each carton through the cartoner. The controller is further arranged for adapting, for each carton, a distance between two consecutive carriers of the transport system in dependence to a size of the first-side-folded carton and driving the two consecutive carriers maintaining the distance.

A packaging unit for packaging articles in boxes includes a mandrel, a movement device, a feeding device, a first abutment surface, and a retaining device. The mandrel is configured to accommodate at least one of said articles inside it. The movement device is configured to move said mandrel along a movement trajectory. The feeding device is configured to feed at least one blank along a feeding trajectory which intersects said movement trajectory towards said mandrel to form one of said boxes around said mandrel. The first abutment surface is defined on said mandrel as the surface of said mandrel intended to abut said blank when positioned in said movement trajectory. The retaining device is displaceable between an operating position in which said retaining device approaches said first abutment surface to retain said blank against said first abutment surface and a non-operating position in which said retaining device is spaced apart from said first abutment surface.
