Packaging machine

Packaging machine comprising a transfer device for inserting a product (P) into a package (V) and with a circulating leaflet supply device (27) comprising a plurality of tong-like holders (15, 16) which are disposed in a row, for receiving one leaflet each, and for bringing the leaflet into the region of the transfer device between the product (P) and the package (V), such that it can be inserted together with the product (P) into the package (V), wherein an opening unit (12) is disposed in the transport path of the holders (15, 16) having at least one stop (13) for opening the holders (15, 16) to release the leaflet, wherein the stop (13) can be adjusted in dependence on an opening signal of a control device (26) between an operative position opening the holders (15, 16) and an inoperative position in which the holders (15, 16) pass the stop (13) without releasing the leaflet, characterized in that a first detector device (19) is provided which detects the insertion motion of the product (P) into the package (V) and transmits a corresponding insertion signal to the control device (26) when the product (P) is being inserted, wherein the control device (26) generates an opening signal only when the insertion signal is present.
