Abstract: A method for automatic packaging of sanitary articles (A) in at least one first type of package (I) and one second type of package (II) containing, respectively, a first number of articles and a second number of articles, envisages: providing a flow of incoming articles diverting (10) articles from said flow of articles with a ratio between non-deflected articles and deflected articles that is a function of the ratio between the aforesaid first number and the aforesaid second number, generating a main flow of non-deflected articles (A) that may be packaged in the packages of the first type (I) and a derived flow of deflected articles that may be packaged in the packages of the second type (II).

Abstract: A device 10 for generating an output flow of articles, starting from a flow of incoming articles having a given advancing velocity, includes a screw conveyor to receive longitudinally the flow of incoming articles. The conveyor in question comprises at least one screw the helix of which is susceptible to interact with the advancing of articles to determine their conveying by the screw itself. The rotational velocity of the screw is adjustable for varying the conveying velocity of the articles with respect to the initial advancing velocity. In particular, it is possible to act so that the conveying velocity of the articles by the screw is a sub-multiple of the initial advancing velocity so that the output flow of articles includes groups of stacked articles. Each group includes a number of articles equal to the ratio between the initial advancing velocity and the conveying velocity of the screw.

Abstract: A device 10 for generating an output flow of articles A, starting from a flow of incoming articles (such as single use absorbent pad products A) having a given advancing velocity vin, includes a screw conveyor 14 to receive longitudinally the flow of incoming articles A. The conveyor in question comprises at least one screw 142 the helix of which is susceptible to interact with the advancing of articles A to determine their conveying by the screw 142 itself. The rotational velocity of the screw 142 is adjustable for varying the conveying velocity of the articles A with respect to the initial advancing velocity. In particular, it is possible to act so that the conveying velocity (vapp) of the articles A by the screw 142 is a sub-multiple of the initial advancing velocity (vin) so that the output flow of articles A includes groups of stacked articles. Each group includes a number of articles A equal to the ratio between the initial advancing velocity (vin) and the conveying velocity (vapp) of the screw 142.

Abstract: A source for supplying lengths of adhesive tape applies such adhesive elements with their outer surfaces facing outwards onto a gripping element consisting of a rotating drum. The drum in question applies the adhesive element on the outer surface of a reel of web material in such a way as to establish adhesive connection with the latter. As a result of a subsequent movement of the drum with respect to the reel, there is formed a loop of web material. Since the loop is separate from the reel, it can undergo a cutting action with the consequent formation of a free flap that can be used for unreeling the web material from the reel. After the web material has been unreeled for a certain stretch and the portion on which the aforesaid adhesive element was applied has been eliminated, on the same web material there may be applied a further adhesive element which is left uncovered for at least part of its surface provided with adhesive.

Abstract: Laminated elements, which may be constituted, for example, by labels to be applied to articles while in movement, are formed from a strip provided by a feeding device. The strip moves forward onto a reception unit, passing through a cutting zone. The individual laminated elements are formed by causing the cutting unit to come into action when the length of the strip paid out by the feeding unit is equal to the desired length of the labels. The cutting unit preferably includes a revolving knife and a counterknife, where the latter consists of a non-driven roller supported in a cradle that is lubricated and exerts an elastic force against the cutting unit. Preferably, the reception unit realizes the step of applying the individual laminated elements to their respective articles.
