Abstract: An apparatus or device is described for forming a continuous and cadenced flow of groups of rolls of paper or other products, coming from the production line or from pre-packaging lines, and rotated by a carousel with horizontal shaft of rotation. The carousel is provided with the blades of L-shaped stalls which pass cyclically and in the right phase between and underneath pairs of supports, to raise the products positioned thereon and set them on a horizontal conveyor. The stalls are controlled to rotate with respect to the carousel in a direction opposite the direction of rotation of the carousel to avoid interference with the products once the products are placed on the horizontal conveyor.

Abstract: Method for packing groups of products or products of prismatic shape with rectangular or square base, which from a feed or grouping unit are then moved towards a first folding spindle so as to be delivered therefrom wrapped in the shape of a “U” rotated through 90° and open at the back, by a packing sheet which is previously placed in front of the spindle with vertical positioning, characterized in that the product with the packing sheet delivered from the spindle are picked up directly and fed in phase between the parallel and horizontal motorized conveyors of a tilting drum positioned inside which longitudinally, edgewise and parallel with each other, are folding devices which guide the product with the packing laterally and fold on the lateral faces of the product the first flaps with vertical folding, projecting laterally and anterior in the feed direction of the packing.

Abstract: Described herein is a method and a unit for the formation of groups of products in a machine for continuous packaging of products, according to which at least two continuous rows of products are fed via two conveyor devices set in series with respect to one another along a first given path and in contact with at least one alignment element, which is set transverse to the first path and in front of the rows of products to align the rows themselves with respect to one another, and is displaced along a second, loop-like, path defined by two portions, along which the alignment element is set on the inside and on the outside, respectively, of the first path.

Abstract: A machine for packaging groups of products ordered in one or more layers, which includes a magazine for the supply of the group of products; apparatus for supplying a packaging sheet the sheet being set vertically to a front face of the product, a pusher for unloading the product; a first-folding spindle set downstream of the wrapping sheet; a pair of horizontal conveyors, set on top of one another, set downstream of the first-folding spindle; a vertical folder, which operates in the short space between the folding spindle and the pair of conveyors; and apparatus to superimpose on the bottom of the product the last transverse end flaps of the packaging sheet; and apparatus for fixing the bottom flaps.

Abstract: Described herein is an apparatus or device for forming a continuous and cadenced flow of groups of rolls of paper or other products, coming from the production line or from pre-packaging lines, and rotated by a carousel (19) with horizontal shaft of rotation (119). The carousel is provided with the blades (235) of L-shaped stalls (35) which pass cyclically and in the right phase between and underneath pairs of supports (9), to raise the” products positioned thereon and set them on a horizontal conveyor (36, 39). The stalls are controlled to rotate with respect to said carousel in a direction opposite the direction of rotation of said carousel to avoid interference with the products once said products are placed on said horizontal conveyor.

Abstract: A packaging machine has a wrapping device for forming a tubular wrapping from a continuous web of heat-seal material, and for feeding products successively into the tubular wrapping; each product being located between two free tubular portions of the tubular wrapping, which are folded substantially onto the relative products, and are stabilized by at least one pair of sealing devices, each of which has a sealing surface heated electrically by a heating device, operation of which is controlled by a control device carried by the sealing device and for determining an actual temperature of the sealing surface.

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.

Abstract: The lower folders (P1, P2) of the packaging machine are driven by a rod and crank system (1, 2) moved by an electric motor (5) with control of speed and phase, regulated by an electronic processor (7) with a corresponding programming and dialogue unit (8). The rod and crank system is designed and arranged in such a way that, when the folders are closed, the rod (1) is aligned with the crank (2), and this position (K) is taken to be the zero position by the said processor and is detected for this purpose by a sensor (6). To drive the folders through a complete cycle of closing and opening, the motor (5) has to execute only one pulse, to transfer the rod and crank system from one to the other of two limit positions (K1, K2), spaced apart from the said zero position by an identical distance which is variable, according to the format of the products to be packaged, by means of the said programming unit (8).

Abstract: At least one driving sprocket (H1) and the neighbouring driven sprocket (H2) carrying the two pairs of chains of the compartment conveyor (T) are connected to each other by means of a dog clutch (2, 4) operated by an actuator (15) controlled by the control panel (19) of the packaging machine. The driving shaft (L) on which the said sprockets (H1, H2) are mounted is turned by an electric motor (1) of the electronic speed and phase control type.

Abstract: The machine comprises a main carousel including a horizontal axis having seats which are angularly equidistant and open outwardly and including at the front a gripper and at the rear a folding device. Each seat passes first adjustable means with the gripper open to supply the gripper with a packaging sheet arranged on the seat, and cooperating with a first auxiliary carousel which inserts a roll into each seat, oriented with its axis parallel to that of the main carousel, while the roll is partially wrapped with the packaging sheet retained by the closed gripper. In succession, the rear folding device intervenes and the gripper opens and folding means intervene in order to fold the front edge of the sheet onto the rear edge, while the folding device returns to the rest position and the edges are fixed together by a heat-sealing carousel.
