The invention relates to a method and device for producing a primary individual packing of a wafer according to which a laminate consisting of a carrier foil and of an active substance film is cross-cut with a predetermin ed length and detached from the carrier foil, is guided between two packaging material webs and, together with these webs, is fed to a sealing station. Th e packaging webs are sealed to form a packet, after which this packet is detached from the packaging material webs. The invention solves the task of providing a method and device which ensure that the wafer material is not subjected to mechanical stress. The inventive method provides that the carri er foil (2) detached from the active substance film (3) is pulled forward to th e predetermined length of the wafer (21), and the active substance film (3) detached therefrom is simultaneously guided with its front end between the stationary packaging material webs (12) without being subjected to mechanica l stress, is held and fixed by these packaging material webs, and is cross-cut with the predetermined length at a distance from the webs to form a wafer (21). Afterwards, the wafer (21) is pulled forward together with the packagi ng substance webs (12) in a synchronous manner and is fed to the sealing statio n (17/18). To this end, the device is provided with a packaging material feedi ng and pulling device (11) having a holding and clamping device (13/14), which is provided for holding and clamping the front end of the active substance film (3) and which, in a vertical direction, is mounted underneath the separating roll (7) and the cross-cutting tool (10).
