Abstract: A flexible, thin, elongated band is used as a substrate. Similarly to a magnetic tape, the band is unwound from a feed reel and is transported past an outlet opening of a receptacle containing the cells such that the cells are poured onto the band. Subsequently, the band containing the cells applied thereon is wound onto a take-up reel. The take-up reel is fixed on a drive shaft which can be rotated by a drive mechanism. The rotation thus achieved has the effect that the band is unwound, transported past the outlet opening and finally wound up. In addition, spacers are provided at the upper surface of the band in order to prevent the contacting of radially adjacent sections of the band containing the cells in a wound-up state.
