A device for supporting containers in filling machines for products in powder form includes, a first supporting element, connected to the structure of a filling machine, and a second supporting element designed to support a respective container to be filled. The device further includes actuation elements configured for actuating, with a vibrating motion, the second supporting element with respect to the first supporting element. The second supporting element can rotate with respect to the first supporting element about a substantially vertical rotation axis. The actuation elements further include elements for generating a variable magnetic field, which are integral with one of the supporting elements, and magnetic means, which are integral with the other of the supporting elements and interact with the generator to cause an alternating oscillation, in the two opposite rotation directions, of the second supporting element with respect to the first supporting element, about the rotation axis.

A variable cam comprises a cylindrical skirt with a track followed by a roller movable along a guide comprised within a rotating structure, which is coaxial to the skirt. The track is interrupted at a portion in the region of maximum elevation of the roller. The cam comprises two arc-like elements proximate to the track portions proximate, on opposite sides, to the interruption. Each arc-like element is guided along a path in which, in each position a portion of a first portion of a side of the element is adjacent to the corresponding portion proximate lo the interruption. A second portion of the side, joined with the first portion, is contained within a plane perpendicular to the skin axis. The presence is determined of a track portion within a plane perpendicular to the skirt axis between the ends of the arc-like elements and is adjacent, in every position occupied by the arc-like elements, to a portion of the second portion.

A method and machine for packing a group of products, whereby the group of products is fed along a first packing path and eased onto a central portion of a blank fed underneath the group, and in the time with the group, along a second path meeting up with the first path; the blank is drawn along said supply path; and at least one further portion of the blank is subsequently folded along a peripheral bend line of the central portion as the group is pressed with a given pressure against the central portion of the blank.

A method and unit for forming, on a cartoning machine, a group having at least one row defined by a given number of products, whereby an orderly succession of products, traveling at a substantially constant first speed, is fed to conveyor traveling at a substantially constant second speed greater than the first speed; a leading product in the succession is braked on the conveyor until a portion of the succession corresponding to the row being formed moves onto the conveyor; and the leading product in the row is then released gradually to accelerate the row up to the second speed and detach the row from the rest of the succession.

A unit for feeding flat diecut blanks of wrapping material to a user machine is equipped with a conveyor by which blanks disposed on edge transversely to a given feed direction and ordered in a substantially continuous column are caused to advance along a conveying path extending toward a transfer station where each blank in turn is picked up from the column; the conveyor comprises two sections aligned along the path: the one, an intermittently driven first belt by which the column is advanced toward the transfer station through a step of predetermined length, at a predetermined frequency timed with the operation of a pickup mechanism positioned at the transfer station, the other a continuously driven second belt designed to advance the column toward the first belt at a predetermined velocity.

Containers are directed onto a carousel rotatable as one about a vertical axis with a tank affording a fluid-tight enclosure and equipped with filler valves, each positionable over the mouth of a relative container; the tank is filled with a liquid substance until a given head has been established, whereupon the enclosure is negatively or positively pressurized, according to the type of liquid substance being handled, in such a way that the jet formed at the outlet of the filler valves will be dispensed at a selected discharge pressure different to the pressure deriving solely from the head of the liquid substance in the tank. The tank is depressurized when filled with foamable liquid substances, and pressurized when filled with viscous substances.

A method and unit for orienting pump-operated caps, whereby a disorderly succession of caps, each having an elongated head and a draw tube extending from the head, is fed on a conveying surface to an engaging station. At the engaging station the draw tube of each cap is engaged by an orienting seat and an elastic cord. The seat is movable with respect to the elastic cord, and cooperates with the elastic cord to rotate the cap about a respective axis of rotation crosswise to the conveying surface, so as to impart a given orientation to the cap.
