A sleeve wrapping device includes a first fixing base, a second fixing base, a first supporting frame protruded from the first fixing base, a second supporting frame protruded from the second fixing base, a first roller mounted on the first supporting frame, a second roller mounted on the second supporting frame, and a sleeve wrapping film comprising a substrate and a plurality of adhesive layers. The first roller and the second roller move back and forth relative to the first supporting frame and the second supporting frame. The sleeve wrapping device is switched between a first state that the first roller and the second roller are in contact with each other and a second state that the first roller and the second roller are separated. The substrate winds the first roller and the second roller.

Controlling application of adhesive on a substrate includes using a gas sensor, obtaining a first sensor signal. The first sensor signal indicates a partial pressure of a gas that arises from a constituent of the adhesive. Based at least in part on this partial pressure, the controller either controls an applicator's delivery of the adhesive to a substrate or causes an error signal indicative of the adhesive's unsuitability for adhesion.

An apparatus and a method are for sealing packages on a flatbed machine. The package is formed from a base-film web and a water-soluble cover-film web. The sealing apparatus includes a liquid supply, at least one moistening unit, and a pressing device for vertically pressing and sealing the cover-film web together with the base-film web. The moistening unit has a moistening roller and a spraying device, the moistening unit being able to be switched between a first operating state and a second operating state. In the first operating state, the moistening roller acts on the cover-film web at a roller moistening location. During or after a machine standstill period, the sealing apparatus is transferred to a second operating state in which the spraying device acts on a spray portion of the cover-film web. The spray portion lies between the roller moistening location and the sealing location in the feed region.

Machinery for packaging articles (15, 15′) in preformed cartons (18), having a conveyor (19) for making cartons travel with an article resting on top of the carton, partially enclosed by the carton, comprising a closing station, in particular having first folding means (24) designed to lift a first side wall of the said carton arranged transversely to the carton progress direction (A) so that it is positioned against the article, in particular towards the rear of the article with respect to the carton progress direction, characterised by the fact that said closing station may be moved parallel to the carton progress direction, wherein the closing station is integral to a sliding surface (20) which is parallel to the surface (26) of the machine on top of which the cartons travel. Packaging method using a machine as described above.

A wetting unit for wetting a surface of one of a first and a second continuous water-soluble films to be coupled and sealingly joined to each other so as to delimit therebetween recesses containing dosed quantities of at least one fluid composition for producing unit dose articles. The wetting unit is configured to wet only surface areas of one of the first and second continuous water-soluble films which are to be joined to the other of the first and second continuous water-soluble films.

A container for food products is defined by a tray (2), which is made of a polymer material, has a bottom wall (3), a side wall (4), and an upper peripheral edge (5), and is provided with a glue layer (16) directly applied on the polymer material of the upper peripheral edge (5) to lock a closing lid (6) on the upper peripheral edge (5).
