DETAILED DESCRIPTION OF THE INVENTION

(6) Referring to the aforesaid drawings and, in particular, to FIGS. 1 and 7, a description is given here below of the apparatus and process for the production of multipage information leaflets or slips suitable for being enclosed with medical-pharmaceutical or cosmetic products or the like.

(7) This apparatus, denoted overall by 10, comprises a plurality of stations, placed in succession, each of which is apt to move the information leaflet and to operate to produce the same as detailed here below.

(8) More particularly the apparatus comprises a loading and feeding station 12, a gluing station 14, a folding and cutting station 16, a transit or transfer station 18, a pressing station 20 and a finished products accumulation station 22.

(9) These stations are arranged in a linear or angular configuration (as in FIGS. 1 and 7) or of another type as a function of the layout features of the system and of further optional equipment combined with said apparatus and necessary, for example, for the packaging process of the product with which the information leaflet is enclosed.

(10) The loading and feeding station 12 is provided with a sheet feeder device 13 apt to take a single sheet from a block or ream of sheets loaded onto said station and, typically, comprising a pneumatic head for the lifting of a single sheet at a time and a drum to drive the same in the direction of the next station.

(11) The gluing station 14 comprises, tendentially, a gluing head 15 having the function of depositing or spraying, hot or cold, small drops of glue or a strip of glue as explained here below.

(12) The folding and cutting station 16 has the function of folding the sheet according to the production specifications and of cutting the excess and unnecessary portions.

(13) The transit and transfer station 18 has the function of moving the sheets coming from the folding and cutting station to a successive station defined by the pressing station 20 which performs an operation of pressing of the folded sheet (as detailed here below) which, subsequently, is transferred to the accumulation station 22 which collects the finished products which are then stored or transferred to other apparatuses for further processes linked to packaging.

(14) The stations described above are, moreover, provided with sensors, meters and optional video-cameras for the acquisition of the production cycle parameters (number of sheets processed, speed, etc.), for the monitoring of the production cycle (for example for the rejecting of defective or non-compliant products) and of the apparatus (for example for the management of machine down times, blockages, periodical maintenance and the like).

(15) In addition to the above described stations of processing and downstream of the accumulation station 22 which collects the finished products or information leaflets formed, the apparatus of the invention can comprise an optional compacting station (not shown in the drawings) apt to allow the compacting of all the information leaflets accumulated in the accumulation station 22 dividing it into reams of information leaflets which can then be transferred to a warehouse or to a packaging station or to stations of folding and insertion in the packaging of the product with which they have to be enclosed and the like.

(16) The apparatus also comprises a control unit suitable for controlling and managing the sequential and synchronised functioning of the working stations on the basis of signals coming from the sensors.

(17) A control panel, not shown in the drawings, is placed on the apparatus 10 with the function of defining an operator interface with the control unit to allow said operator the visualisation of the processing steps, the control of the production cycle, the variation of the processing parameters as a function of the formats of paper optionally used, etc.

(18) The process for the production of the multipage information leaflet by means of the apparatus 10, described above with reference to its component parts, is detailed here below.

(19) More particularly the process of the invention produces the multipage information leaflet or slip from a single sheet 26, with tendentially rectangular development, whereon is printed, on one or both sides (in FIG. 2 a single sheet printed on only one of the two sides is schematised), all the information which will go to characterise the single pages which can be browsed of the information leaflet to be associated with a specific product.

(20) As schematised in FIG. 2 the single sheet 26 comprises a plurality of parallel imaginary lines 23 (denoted by a dotted line in FIGS. 2 to 4), arranged transversely with respect to the direction of longitudinal development of the sheet and apt to define wings or portions 25 defining single pages 27 (FIG. 6) of the information leaflet as described in detail here below.

(21) The single sheets 26 organised in a ream 24 are loaded into the loading and feeding station 12 where the sheet feeder device 13 takes a single sheet 26 (by means of the pneumatic head) and moves it (by means of the drum) in the direction of the successive gluing station 14, where the gluing head 15 deposits or sprays drops of glue or a layer of glue along a zone or band 28 of a side of said single sheet 26 developed along an entire edge of the sheet 26 at its long side.

(22) Alternatively the glue can be deposited or sprayed along an edge at the short side of said sheet 26.

(23) The sheet, subsequently, transits in the station of folding and cutting 16 where it is folded and cut, as schematised in FIGS. 4 and 5.

(24) More particularly the sheet 26 is folded on itself along the imaginary lines 23 (transversal with respect to the direction of longitudinal development of the single sheet 26 and therefore with respect to said zone 28 of the edge of the sheet provided with glue) in a direction indicated by the arrow A (FIG. 4) starting from a wing 25 defining a single page positioned at one end of the single sheet 26 and in the direction of the opposite end in such a way that said wing is superimposed on the successive and adjacent wing to define a folded sheet 30 (FIG. 5) in which, through the effect of the folding, the zone of gluing 28 is placed at the short side of the folded sheet 30, and maintains integral said single pages.

(25) The folded sheet 30 is, subsequently, subjected to a cutting process performed along further imaginary lines of cutting 32 (FIG. 5) at opposite edges of the long side, i.e. of said opposite transversal edge portions of said folded sheet 30 to define a multipage information leaflet 34 comprising the two or more pages 27 integral one with the other at a joining area 29 defined by the band provided with glue 28, as schematised in FIG. 6: in this way the information leaflet can be browsed.

(26) The information leaflet 34 formed in this way passes, subsequently, in the transit and transfer station 18, placed in succession to the folding and cutting station, for a movement, by means of rollers or in another known and equivalent manner, in the direction of the pressing station 20 where the joining area 29 defined by the gluing band 28 is pressed (for example by means of rollers) in order to avoid the formation of humps or irregularities which can jeopardise the good quality of the finished product.

(27) The multipage information leaflet 34 can subsequently be stacked in reams and stored in the warehouse or moved in further production lines where it is subjected to folding operations and insertion in a container of a specific product whereto said leaflet is associated.

(28) As can be seen from the above, the advantages that the process and the apparatus of the invention achieve are clear.

(29) The process for the production of information leaflets of the present invention allows, advantageously, the production of information leaflets or slips with multiple pages (two or more) starting from a single sheet printed on one or on both the sides so as to avoid disadvantages linked to the presence of blank pages or of pages not corresponding to the product with which said information leaflet has to be enclosed.

(30) A further advantage is represented by the fact that the process of the invention, starting from a single sheet subsequently glued, folded and cut, allows the times of the production cycle to be reduced with a consequent advantage in terms of production costs.

(31) A further advantage is represented by the fact that the working stations of the apparatus of the invention are flexible and can be reconfigured so as to be able to manage the production of information leaflets or slips with different formats.

(32) Although the invention has been described above with particular reference to one of its embodiments given solely by way of a non-limiting example, numerous changes and variations will appear clear to a person skilled in the art in light of the description given above. The present invention intends, therefore, to embrace all the modifications and the variations that fall within the scope of the following claims.
