Abstract: A process for introducing a plurality of segregated sheet-like administration forms into a dispenser under formation of a multilayered stack for individually dosable removal, with sheet-like tapes wound-up on rolls being present as starting material, utilizes the following steps. In a first step, a number of sheet-like layers of said tapes, which number corresponds to the stack, is simultaneously drawn from a plurality of rolls. In a further step, the individual tapes are united, using guide means, to form a multilayered strand, which in yet another step, is drawn forward to a cutting station where one length of stack is severed at a time, and wherein a length segment of the multilayered strand corresponding to the stack is substantially in the dispenser prior to being severed from a remainder of the multilayered strand by the cutting device.
