Abstract:
1. A process for manufacturing a primary unit pack of a wafer, the wafer having a predetermined length and a predetermined width, the process comprising the following steps: providing a laminate comprising a carrier sheet and an active substance film being detachably connected to said carrier sheet and having a front end; providing two packaging material webs; partially detaching said active substance film from the carrier sheet; pulling said carrier sheet forward, and thereby also the active substance film, forward over the predetermined length of the wafer that is to be produced; while pulling said carrier sheet forward, simultaneously guiding said detached active substance film, with its front end first, between said two packaging material webs while these webs are in a resting condition, without subjecting said active substance film to a mechanical stress, and whereby the active substance film is fixed between said two packaging material webs; after guiding said detached active substance film between said two packaging material webs, transversely cutting said active substance film at a distance from said two packaging material webs to form a wafer of the predetermined length; pulling the wafer forward together and synchronously with said two packaging material webs while the wafer is fixed between these webs; conveying the wafer and said two packaging material webs forwardly to a sealing station; sealing the packaging material webs outside of the area of the wafer to form a pouch or bag enclosing said wafer; and separating said pouch or bag from the packaging material webs.
