Abstract:
An apparatus for the entry of a fiber band into a drawing unit, said apparatus comprising:a condenser disposed upstream from the drawing unit in a direction of travel of the fiber band to condense and guide the fiber band from a preceding process into the drawing unit, said condenser having longitudinally extending structure defining a passage through said condenser from a first side to an opposite second side disposed towards the drawing unit; wherein said condenser further comprises a longitudinally extending opening in said structure from said first side to said second side, said opening being open and accessible along the length thereof in an operating mode of the drawing unit for insertion of the fiber band longitudinally into said condenser; a fiber feed device disposed downstream from said condenser, said fiber feed device guiding said fiber band towards said drawing unit, wherein said fiber feed device is a roller pair, wherein at least one of the rolls in said roller pair is a driven feed roller; a measuring apparatus disposed to continuously measure the density of said fiber band before it enters the drawing unit, wherein said measuring apparatus comprises a sensor configured with said roller pair; and wherein said regulator communicates through said control device with a storage unit for said fiber band, said storage unit being positioned after said preceding process and before said fiber band enters said condenser.
