What is shown is a spinning device (1) and a method for spinning up a spinning device (1) for the continuous extrusion of molded bodies (3) from a spinning solution (6), as well as a spin-up device (11) for the execution of the method, in which method the molded bodies (3) are extruded from the spinning solution (6) through spinnerets (7) of the spinning device (1) in the form of a loose spinning curtain (2), the molded bodies (3) of the loose spinning curtain (2) are, after the extrusion, combined into a molded body bundle (4), and the molded body bundle (4) is, in a further step, fed to a draw-off member (10) of the spinning device (1) in order to start a continuous extrusion of the molded bodies (3). In order to make the method for spinning up the spinning device (1) simpler and more reproducible, it is proposed that the molded bodies (3) be combined into the molded body bundle (4) by twisting the spinning curtain (2) around a torsion axis (20).
A spin-up device for spinning-up a spinning device, which comprises a bundling device for bundling of molded bodies from a loose spinning curtain extruded from spinnerets of a spinning device into a molded body bundle, which bundling device includes a rotation device configured to be used during spin-up, wherein the rotation device comprises at least one turntable that is rotatable around a rotation axis, the turntable being configured such that the molded bodies are combined into the molded body bundle with the help of said turntable, wherein the turntable is for the torsion of the molded bodies, and that the rotation axis of the turntable is substantially parallel to the extrusion direction of the molded bodies, wherein the rotation device is configured to receive ends of the molded bodies from the loose spinning curtain so that the ends of the molded bodies are deposited on the turntable and the turntable is configured to generate a torsion of the loose spinning curtain.
Use of a spin-up device for spinning-up a spinning device, wherein the spin-up device comprises a rotation device configured to be used during spin-up, wherein the rotation device comprises a turntable that is rotatable with respect to the spinning device, for bundling of molded bodies from a loose spinning curtain extruded from spinnerets of the spinning device into a molded body bundle by twisting the molded bodies by the turntable, wherein the rotation device is configured to receive ends of the molded bodies from the loose spinning curtain so that the ends of the molded bodies are deposited on the turntable and a torsion of the loose spinning curtain is generated by rotating motion of the turntable.
