Abstract: A unit for preparing groups (1) of products in layers (S) for palletizing comprises: a motor-driven element (4) for controlled pick up and release of the groups (1) of products from the first surface (3) to a second surface (5), positioned by the side of the first surface (3), for preparing a layer (S) of groups (1) of products; a logic unit (7) for controlling and programming the pick up and release element (4) and the second surface (5) to obtain individual layers (S) made up of two or more groups (1) of products on the second surface (5) by moving them along or around axes, transversal (Y) to the extension of the first surface (3), parallel (X) with the extension of the first surface (3), at a vertical height (Z) and according to an angle (?) of rotation about the vertical axis (Z); the pick up and release element (4) having independent drive units (9, 10, 11) designed to control the element (4) according to three of the controlled axes (X, Y, Z, ?); the second preparation surface (5) having a drive unit (

Abstract: A machine for producing groups (1) of products comprises: a station (3) for grouping a plurality of groups (1); a first surface (4) for receiving the plurality of groups (1) of products arriving from the station (3) to form a batch (L) of products; a first, programmable logic unit (5) for checking and controlling the grouping station (3) and the first surface (4); a palletizing island (6) for groups (1) of products fed by the first surface (4) and comprising a second logic unit (7) for managing and programming at least two robotic units (8, 9) for handling the groups (1) of products, so as to obtain, respectively, individual layers (S) of two or more groups (1) of products, and relative positioning of the layers on pallets (10); means (11) for forming sub-batches (SL) starting with the original batch (L), when required, said means being positioned between the grouping station (3) and the first surface (4), and connected to the first logic unit (5); an interface unit (12), inserted between the first logic unit

Abstract: A machine for the production of groups of rolls of products, each group consisting of a plurality of products grouped together to constitute a format and wrapped and closed in a sheet of film. Along a feed line the machine comprises: a first unit for transporting the groups of products one after another towards a second unit for picking up and grouping a plurality of groups of products; a first work surface with batch selection and forming means; a programmable control unit controlling the selection and forming means and the second unit, and designed to allow, immediately downstream of the second unit, relative to the feed line, formation of the batches of products depending on their type of destination downstream of the second unit.

Abstract: A method and system for packaging rolls of products, in particular rolls of toilet and/or kitchen paper, in which a wrapping sheet is wrapped in a “U” shape around a group of products so that its two end flaps project from the group, each of the end flaps then being folded in an “L” shape so that one portion adheres to the group and the remaining end portion extends transversally to the group and adheres, at the point where they meet, to the end portion of the other flap; the flaps then being sealed to one another at their end portions to form a tubular wrapper.
