Abstract: 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.

Abstract: Flat articles to be formed into groups for packaging are advanced in succession at a set tempo toward a transfer station where each article is made to assume a predetermined position in space, standing on edge. Thereafter, the articles are advanced in a direction perpendicular to the position in space and toward a release station by means of a first conveyor equipped with pockets. The articles are caused to advance at a first linear velocity in such a way that each pocket receives an article and, at predetermined intervals, are accelerated to a second velocity for a predetermined duration between the arrival of one article at the transfer station and the arrival of the next article. In this way, one or more pockets remain empty, and groups of articles forming on the conveyor are separated one from the next by the empty pockets.

Abstract: On a conveying device for forming and conveying groups of products, a screw conveyor is supplied at the input with an orderly succession of products, and has an input portion along which the products are formed into groups, and a tubular output portion for feeding the groups separately and successively to a pocket conveyor extending inside the output portion and having a number of push and lead members, each separating two adjacent pockets on the pocket conveyor.

Abstract: An ordering device for arranging products received in the loose state in an orderly succession comprises a first and a second conveyor with belts defining a product feed path divided into active portions with variable lengths equaling complementary fractions of the total length of the path; a pair of transmission pulleys, respectively connected to the first and second conveyors to define the active portions and supported by a carriage which moves in both directions along the path; drive means designed to move the transmission pulleys so as to vary the length of the portions; compensator means for compensating the variations in the length of the active portions of the path with corresponding opposite variations in the length of the respective complementary sections of the belts; the device comprises one carriage and the compensator means comprise mechanisms equipped with rigid elements which are connected to one another and which connect the carriage and the belts and vary their geometric configuration accordi

Abstract: 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.

Abstract: 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.

Abstract: In a method for aligning products, the products, being substantially aligned in crossways rows on a first conveyor, are carried by the first conveyor in hollows made in trays through a pickup position at which the products in each row are picked up by a suction head which, while remaining parallel to itself, moves in a circular path extending partly over the first conveyor. The suction head transfers the products along a portion of its path between the pickup position and an unloading position at which the products are dropped onto a second conveyor equipped with hollows so that the products are arranged in a single line, with one product in each hollow.
