Abstract
An electrostatic fiber collecting and yarn spinning apparatus is substantially improved by adding a bowl-shaped electrode and changing the configuration of the electrodes so that the rotating electrode is substantially enclosed by the stationary electrode.
Claims9
In a yarn spinning apparatus of the type comprising a stationary electrode, a rotatable electrode spaced from the stationary electrode and means connected to said electrodes for establishing and maintaining an electrical field between them, and said stationary electrode having an opening axially aligned with the rotatable electrode through which the formed yarn is withdrawn, the improvement characterized by:
- a. a stationary electrode which
- 1. substantially encloses the rotatable electrode by extending, in a direction parallel to the axis, at least to the plane of the greatest diameter of the rotatable electrode,
- 2. has a surface opposing the rotatable electrode which is round in all planes perpendicular to the axis of the rotatable electrode, and
- 3. is positioned so that its axis is coincident with the axis of the rotatable electrode, and
- b. the two electrodes being a corresponding size and shape so that the space between their opposing surfaces increases in a direction radial from their common axis.
