The invention relates to a method for the continuous production of infusion bags, in particular for tea, by depositing single substance quantities (3) on a filter paper web (2) and forming a tube as well as forming individual chambers (6), which are closed on all sides and at least contain one substance quantity (3), respectively, and which are attached to a carrier material (12). According to the invention, the chambers (6) are formed by a transverse seam (9), which simultaneously comprises the rear seam (9a) of the one infusion bag and the front seam (9b) of the succeeding infusion bag and a perforation (9c) interposed between both seams (9a and 9b), at which the infusion bags are separated in course of the process.
