An apparatus for producing a packaged unit includes a separating device, a shrinking device, and a manipulation unit. The separating device separates out individual products from a product stream and combines them to form a product cluster. The shrinking device secures the product cluster on all sides by applying a shrink film wrapped around the product cluster in a way that forms at least one lateral opening before being shrunk on. The manipulation unit places the shrink film against the product cluster at least in the region of the lateral opening, thereby forming a closed surface in the form of a closure with overlapping fold regions.

A packer machine for producing pouches containing portions of a loose product having: a frame; a conveyor device configured to move two bands of wrapping material along two parallel packing paths; a wrapping station arranged along each packing path at which the corresponding band is wrapped to form a tubular wrap; a longitudinal sealing unit with at least two sealing elements; a feeding device with two feeding ducts around each of which a band is bent to form the corresponding tubular wrap, each being configured to feed, one after the other, the loose product into the corresponding tubular wrap; two movable assemblies, each being mounted on the frame to move along a pressing direction independently of the other movable assembly and supports one single corresponding sealing element; and two actuator devices, each of which applies an elastic force to a corresponding movable assembly independently of the other actuator device.

A flow wrapping apparatus displaces a number of packs from a first location where the packs are self-standing on their lower region to a second location where the packs are on edge to form a substantially horizontal stack. The apparatus includes first and second conveyors with a number of individually displaceable hands. The hands of the first conveyor displace packs from a first location where the packs are self-standing on their lower region to a second location where the packs are on edge. At least one of the hands of the second conveyor cooperates with at least one of the hands of the first conveyor to hold packs on their edge to form a substantially horizontal stack. A pair of individually displaceable hands of the second conveyor displace the stack towards a flow wrapping station.

A packing method for applying a heat-seal overwrap to a package of tobacco articles having an inner container, which houses a group of tobacco articles; an outer container housing the inner container in sliding manner; and a hinged lid, which closes an open top end of the inner container; the packing method including the steps of folding a sheet of heat-seal wrapping material into a tube about the package to form a tubular wrapping; folding two ends of the tubular wrapping to complete the overwrap; stabilizing the overwrap with two transverse heat seals; and, at least when making the transverse heat seals, compressing a front wall of the outer container, so as to move at least part of a top edge of the front wall of the outer container beneath a top wall of the lid.

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.
