Zusammenfassung:	The present application relates to a method and apparatus for manufacturing an agglomeration of glass beads consisting of a plurality of glass beads bound together by means of a binder material. An apparatus is described which includes a dispensing device (3a; 3b; 3c) having a plurality of channels (5) along which, in use, binder material flows. Each of the channels terminates in an outlet (8) and is in fluid communication with a single binder inlet (6). Importantly, the channels are of substantially identical length and diameter. One or more dispensing devices may be coupled to a single distribution unit (2).
