Disclosed is a packaging machine comprising a transfer device by means of which a product (P) is inserted into a package (V) and a circulating leaflet conveying device (27) that is provided with a plurality of tong-like holders (15, 16) which are serially arranged and each of which receives one leaflet. Said leaflet is placed between the product and the package in the area of the transfer device by means of the leaflet conveying device such that the leaflet can be inserted into the package along with the product. An opening unit (12) comprising at least one stop (13) is disposed along the conveying path of the holders, said opening unit (12) opening the holders so as to release the leaflet. The stop can be switched between a functional position in which the holders are open and a non-functional position in which the holders run past the stop without releasing the leaflet according to an opening signal of a control device (26). The inventive packaging machine also comprises a first detector device (19) which detects the inserting movement of the product into the package and emits a corresponding insertion signal to the control device when a product is inserted, the control device generating the opening signal only if an insertion signal has been emitted.

L'invention concerne une machine d'emballage comportant une unité de transfert, au moyen de laquelle un produit (P) peut être introduit dans un emballage (V), et une unité de transport de prospectus (27) rotative qui présente une pluralité de supports (15, 16) en forme de pinces, alignées, servant à recevoir respectivement un prospectus, ladite unité de transport de prospectus (27) permettant de placer le prospectus entre le produit et l'emballage, dans la zone de l'unité de transfert de sorte que ledit prospectus puisse être inséré avec le produit dans l'emballage. Sur le parcours de transport des supports est placée une unité d'ouverture (13) comportant au moins une butée (13) permettant aux supports de s'ouvrir pour libérer le prospectus. La butée peut être déplacée en fonction d'un signal d'ouverture d'une unité de commande (26) pour passer d'une position fonctionnelle d'ouverture des supports à une position non fonctionnelle (et réciproquement), position non fonctionnelle dans laquelle les supports passent devant la butée sans libérer le prospectus. Ladite machine d'emballage comprend un dispositif de détection (19) qui détecte la course d'insertion du prospectus dans l'emballage et qui, lors de l'insertion du produit, émet un signal d'insertion correspondant, à destination de l'unité de commande, cette dernière produisant le signal d'ouverture uniquement en présence du signal d'insertion.
