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.

An assembly for folding and heat-sealing at least one tubular portion constituted by flaps of packaging sheets which protrude with respect to opposite fronts of a product arranged on a conveyance line, comprises: a folding station provided with at least one folding plate having a width that is smaller than that of the product and of the tubular portion and at least one folding bar; at least one heat-sealing block, of shape and dimensions that are complementary to those of the lateral end of the tubular portion and movable between a passive configuration, in which it is spaced apart from the lateral end, and an active configuration, in which it abuts against the lateral end, following a release of the lateral end by the folding bar; at least one heat-sealing plate, arranged downstream of the folding station along the conveyance line.

A packaging unit for packaging articles in boxes, including a mandrel, a movement device, a feeding device, a folding device, and an actuation 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 at a desired movement speed. The feeding device is configured to feed at least one blank towards said mandrel along a feeding trajectory which intersects said movement trajectory. The folding device is intended to abut said blank and is configured to cooperate with said mandrel to fold said blank around said mandrel when said blank is positioned between said mandrel and said folding device to form one of said boxes. The actuation device is configured to displace said folding device along at least one folding stroke with an accompanying speed having at least one accompanying component with the same direction as the movement speed of the mandrel and modulus lower than the movement modulus in said folding stroke.

A method and system for forming a package that addresses operational challenges in container packaging systems. The system may include a conveyor to propagate the blank and the plurality of containers at a first velocity through the system, the blank includes a main panel having a plurality of apertures, a left clip enclosing panel foldably coupled to a first side of the main panel and a right clip enclosing panel foldably coupled to a second side of the main panel. The system further includes a latching tool including a blade member configured to travel in an eccentric path such that the blade member is arranged to move vertically to secure a portion of the clip enclosing panel to a first set of containers while simultaneously moving horizontally at the first velocity.
