Abstract

A method for the multi-track tailoring of transdermal therapeutic patches having at least a one-layer, adhesive reservoir foil containing an active ingredient, which is disposed between an adhesive back foil and a removable protective foil. The reservoir foils are applied per track with their adhesive layers on a transport element moving discontinuously in the longitudinal direction of the reservoir foils. After separating sections of the size of a patch or band aid the same are transferred to a further transport element that is moved continuously for depositing the same thereon in spaced relationship. The present invention provides a method for multi-track tailoring, wherein web-shaped reservoir foils, which can be unwound from rolls, may be utilized without producing any waste containing the active ingredient.
