Abstract: A machine for packaging fiber material comprises feed means (2) supplying predetermined portions of fiber material (3) in an ordered succession, compacting means (4) by which the portions of fiber material (3) are compacted initially, a feed station (8) to which packs (9) are supplied for filling with the fiber material (3), a filling station (D) at which the fiber material (3) is inserted into the packs (9), and a closure station (E) located downstream of the filling station (D), at which the filled packs (9) are sealed. The machine further comprises fiber material (3) compressing and forming means (7) by which each of the portions of fiber material (3) is maintained in a state of compression downstream of the compacting means (4) for a prescribed interval of time, in such a way that the selfsame portion of fiber material (3) is caused to assume a compact geometry of tablet-like form prior to its insertion into the respective pack (9).

Abstract: Products (3) advancing in single file are divided into at least two files by a device comprising a main conveyor (10) from which the products (3) of the single file (7) pass onto a first outfeed conveyor (11) and onto a second outfeed conveyor (12) positioned with infeed ends at different heights, one above the other; the device also comprises a linking conveyor (26) between the main conveyor (10) and the outfeed conveyors (11, 12), consisting in a pair of looped belts (27, 28) presenting outer surfaces faced along a portion of predetermined length with a layer (35) of resilient material, thereby creating a channel (34) by which the main conveyor (10) is linked to the outfeed conveyor (11) positioned uppermost, and along which the products (3) are transferred cyclically to this same conveyor (11).

Abstract: A packaging machine or machine unit, as used in particular for capping containers (5), is enclosed by a structure (1) that comprises a casing (2) positioned at least in part around the active components (3) of a packaging unit (4) supplied with open containers (5).

Each gripper mechanism (5) is switchable between a first configuration, establishing a recess (6) in which to accommodate a respective container (3), a second configuration in which the container (3) is retained within the recess (6) by a predetermined gripping force, and a third configuration in which the container (3) is restrained by a gripping force greater than the force exerted in the second configuration, so as to counteract any unwanted rotation of the container (3) about its longitudinal axis (Y) that might be induced during the course of capping operations.

Abstract: In a machine for wrapping sticks of chewing gum, sticks of substantially rectangular outline and relatively small thickness advance singly and in succession on a conveyor, arranged flat and spaced apart at a predetermined first pitch, toward a position where they are transferred to a spacing roller revolving tangentially to the conveyor and presenting peripheral seats spaced apart at a pitch greater than the first pitch; the sticks are taken up at the transfer position by a pick-up and transfer mechanism operating between the conveyor and the seats of the spacing roller, describing a trajectory that includes a movement perpendicular to the plane occupied by the sticks and producing a minimal displacement equating approximately to the thickness of a single stick.
