Abstract: The device includes a stacking surface movable in a substantially vertical direction, on which layers of products to be packaged are superposed, and a pair of conveyors substantially superposed to feed the layers of products to the stacking surface. The device also includes a pair of walls substantially parallel, and substantially vertical, between which the layers of products are inserted by the conveyors when they are stacked on the stacking surface. The walls move reciprocally towards and away from each other to take a position of greater reciprocal distance, in which they do not interfere with the products deposited on the stacking surface, and a position of lesser reciprocal distance, in which they interfere with the products inserted therebetween.

Abstract: A conveyor device, in particular for an automatic packaging machine for paper rolls, having a horizontal plane of advance, at least one pair of motorized flexible transmission members extending along a closed loop and bearing a plurality of transverse bars fastened to said flexible transmission members, a plurality of thruster elements borne by said bars, and a stationary adjustment station provided with at least one adjustment assembly having a grip organ movable in transverse direction and arranged in such a way as to displace in the transverse direction along the respective bar a thruster element positioned at the grip organ.

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: There is described a machine for forming groups of ordered products, each group including products disposed according to superposed layers. The machine includes a succession of conveyors aligned according to a principal direction of alignment, with a feed conveyor and a delivery conveyor. The feed conveyor receives single layers of products aligned with and spaced from one another; and the conveyors are disposed and controlled so as to distribute layers of products on a predetermined number of levels at different heights, and to unload onto the delivery conveyor a predetermined number of layers, superposed on one another, equal to the predetermined number of the levels at different heights.

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: To orient groups of products to be packaged in a plastic film the groups (G) are wrapped in lengths of film and fed between two series of opposite conveyor belts (211, 212). Each series of belts comprises several parallel belts controlled at proportionally variable speeds to cause the group (G) to rotate through approximately 90° about an axis orthogonal to the direction of feed.

Abstract: The formation of a group (2) of rolls (3) of paper arranged according to a first number (h) of overlaid layers (4) is performed by feeding the layers (4) onto an elevator platform (8) by means of at least two feed conveyors (11) positioned one on top of the other; the method providing for initial loading onto the platform (8) of a number of layers (4) at the most equal to the number of feed conveyors (11), lowering of the platform (8) by a distance equal or slightly greater than the height of the layers (4) just loaded and, lastly, loading onto the platform (8) and onto the layers (4) already loaded of a number of layers (4) at the most equal to the number of feed conveyors (11).

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: 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).
