The invention shows a spin-up device (11, 51) and a method for spinning up a spinning device (1, 101) for the continuous extrusion of molded bodies (3) from a spinning solution (6), containing a solvent and cellulose dissolved in the solvent, wherein the molded bodies are extruded from the spinning solution (6) through spinnerets (7) of the spinning device (1, 101) in the form of a loose spinning curtain (2), the molded bodies (3) of the loose spinning curtain (2) are combined into a molded body bundle (4) after the extrusion, and the molded body bundle (4) is, in a further step, fed to a draw-off member (10) of the spinning device (1, 101) in order to start a continuous extrusion of the molded bodies (3). In order to make the spin-up method simpler in terms of process technology and more reproducible, it is proposed to increase the tensile strength of at least some areas of the molded bodies (3) of the loose spinning curtain (2) after their extrusion and before combining them into a molded body bundle (4).
A method for spinning up a spinning device for the continuous extrusion of molded bodies from a spinning solution comprising a solvent and cellulose dissolved in the solvent, wherein
A spin-up device for spinning up a spinning device comprising a bundling device for bundling of molded bodies extruded from the spinnerets of the spinning device into a molded body bundle, wherein the bundling device includes a rotating member that is configured to twist the molded bodies around a torsion axis to combine the molded bodies into the molded body bundle, wherein the spin-up device includes a first manipulator arm with a first end effector, the first end effector including a gripper configured to grab the molded body bundle, and wherein the bundling device and manipulator arm are configured to spin-up the spinning device.
