Abstract: The invention concerns a tin packaging arrangement comprising a sheet of foldable material folded around a plurality of tins, which are arranged together in an orderly manner for the relative packaging, to form a containment volume for the tins themselves, said volume being substantially defined by a base, a side surface, and a top cover obtained from the sheet in a continuous way. A peculiarity of the present invention is that openings are made in the top cover of the sheet of the packaging arrangement, within which top portions of the tins engage.

Abstract: A working process of a machine for wrapping products in packages, carried out with a thermoplastic material film from a reel, the process comprising: reducing a transversal section of a hollow mandrel to be smaller than a transversal dimension of a bundle of products, positioning a sealing device in a position for sealing overlapped longitudinal edges of the film while forming a new tubular film casing, arranging two vertically mobile elements of a sealing and transversal cutting assembly in a closure position on the head portion of the new tubular film casing and on the tail portion of the tubular film casing of a finished package, and conveying the new tubular film casing away from the mandrel, and repeating the process so that the product placed inside the tubular casing by the mandrel is wrapped in a tight adherent manner due to the elastic retraction of the film.

Abstract: The apparatus is formed of two identical devices (A, A?) installed mirror image-fashion, each of which is equipped with a pressure bar (19, 19?) fitted to overhang the relevant lateral toothed conveyor belts (T, T?) which move and recircle the sai bars, and which are in their turn activated by relevant motors (8, 8?) with electronic speed and phase control governed by one programmable processing unit (26). When the length of the products (P) is less than the length of the straight branches of the conveyors moving the said bars, the two devices are installed mirror-image fashion, with the axles of the pulleys of one conveyor aligned with those of the corresponding pulleys of the other conveyor. In this position, the bars (19, 19?) of the two devices alternate in taking, moving foward by pushing and the final placing of the product in the workstation (K).

Abstract: The thrust bars (11), which are placed behind the product in the transfer phase from a first transport line (L1) to a downstream line (L2), have an adjustable stop (12) resting against the one side of the product in the direction of travel of this product. Articulated joints (10, 10?), connect the ends of the bars to corresponding points of the upper branch or the lower branch of a parallel pair of toothed belt conveyors (T, T?) fed on pulleys with horizontal axles, which are inclined at a right angle to the conveyors (T,T?) which bridge the area between the two transport lines and which with their one branch, work in the direction running from the upstream line to the downstream line at an identical speed to each other such as to be able to effect, with the above-mentioned bars, the transfer of products from one conveyor belt to the other by rear and side thrust.

Abstract: The apparatus comprises a pair of parallel conveyors (T1, T1′) with vertical motorized axes (101, 101′), formed by any flexible heat-resistant and air-permeable structure, the inside run of which contacts with appropriate pressure the sides, containing the folded-down flaps to be sealed, of the packaging (P), which is supported from beneath by for example an optional horizontal motorized conveyor (T) travelling in the same direction and at the same speed as the said inside runs of the said lateral conveyors arranged longitudinally behind which are tubular electrical resistors (6, 6′) heatable by the joule effect and of low thermal inertia, that dispense jets of hot air through the active inside runs of these conveyors and that are incident upon the flaps of the packagings, in order to produce weld lines thereon. Subsequent means (10, 10′) are provided to maintain an appropriate pressure and to cool the said weld lines, before the packagings leave the said apparatus.
