For the production of an agglomerate, a portion of the fiber material is introduced into a ring-shape roller table which closed on all sides except for an input opening an an output opening. The fiber material portion introduced into the roller table is transported through the roller table by means of a relative movement of two surfaces of the roller table toward each other, the surfaces lying opposite each other. The fiber material is compressed in the roller table and finally discharged from an output opening of the roller table as fiber agglomerate. According to the invitation, the portioning of the fiber material is carried out by the pulling of an amount of fibers out of a stock of corresponding fiber materials is provided on a supply table for each input opening of a roller table, and portions are continously pulled out of said stock by the repeated movement through the sock of carrier means of a pulling device designed therefor and released into the roller table.}, language = {en} } @misc{AyGusoviusHildebrandt, author = {Ay, Peter and Gusovius, Hans-J{\"o}rg and Hildebrandt, Sven}, title = {Verfahren und Einrichtung zur Herstellung von pelletartigen K{\"o}rpern aus ungebundenen Fasern}, language = {de} }
