摘要:
Machines manufacturing pouches of a smokeless tobacco product or other cohesionless material, and systems for portioning and packaging tobamel type smoking mixtures, can be fitted with a flushing device that uses a number of spray nozzles (12, 31) positioned in close proximity to units (6, 30) by which the smokeless and smoking tobacco products are conveyed and processed; with the machine or system in operation, a cleansing fluid held in a tank (14, 33) is supplied under pressure to the nozzles (12, 31) by a pump (15, 34) and directed onto internal parts of the units (6, 30) in order to remove deposits of the product that tend to accumulate in the course of the processing steps, and thus avoid the need for frequent cleaning and maintenance stoppages.

A machine manufacturing pouches of a smokeless tobacco product, or other similarly cohesionless material, comprises a feed system (100) by which the tobacco is supplied to a conveyor (4) at a delivery station (5), from where it is transported by the conveyor (4) to a transfer station (6), also a system (102) operating at the transfer station, (6) by which predetermined portions (7) of the product are directed from the conveyor (4) into at least one duct (16) linked to a form-fill-and-seal wrapping station (8) where, the portions (7) are enclosed in a continuous succession (101) of pouches (2). The wrapping station (8) is equipped with ultrasonic welders.

The neck of a container for free-flowing food products appears as a duct (1), composed of a tubular element (6) and a connecting portion (7) that combine to establish a flow passage (8) between the container and the surrounding environment; the connecting portion (7) is moulded in one piece with the tubular element (6) and presents a mating surface (11) sealable hermetically to an outlet portion (5) of the container. The mating surface (11) consists of low density polyethylene, whilst the duct (1) includes at least one material of strength superior to that of low density polyethylene.

An ultrasound sealing device (15, 20, 21), wherein an activating device (2), for generating vibrations of a wavelength of a given value L, has a first surface (11) contacting a second surface (17; 22) of a sonotrode (3); the activating device (2) and the sonotrode (3) having, respectively, a first and a second nodal surface (4, 5) substantially parallel to each other; and the second surface (17; 22) being located at a distance from the second nodal surface (5) of more than zero and less than L/4.

In a machine for making rigid hinge-lid packets, the lid of each packet is folded by a device ( 9 ) equipped with a plurality of pockets ( 2 ) occupied by respective single packets (P), each presenting a set of end folds ( 20 ) that will be bent inwards to form the lid ( 15 ), also, a belt conveyor ( 3 ) by which the pockets ( 2 ) are directed along a predetermined folding path ( 3 b) between an infeed point ( 10 ) and an outfeed point ( 11 ), a pulley ( 4 ) centred on a vertical axis (X) of rotation, and a folder unit ( 12 ) mounted to the rotating pulley ( 4 ), interacting with a top part ( 13 ) of each pocket ( 2 ) in such a manner as to engage and bend the end folds ( 20 ) of the packet (P). The folding path ( 3 b) coincides with a branch of the belt conveyor ( 3 ) looped around the pulley ( 4 ).
