Abstract
A yarn wetting apparatus, especially for a two-for-one twisting spindle assembly, and a two-for-one twisting spindle assembly having a yarn wetting apparatus disposed on the upper end of its spindle hollow axis, are provided. The yarn wetting apparatus comprises a reservoir, a porous wetting body which extends to the reservoir and has a capillary capacity, and a yarn passage opening which tapers in the direction of the spindle hollow axis of the two-for-one twisting spindle assembly, wherein the inner end of the yarn passage opening is in communication with the reservoir via at least one wetting agent back flow channel.
Claims10
A yarn wetting apparatus particularly suitable for a two-for-one twisting spindle assembly, the two-for-one twisting spindle assembly including a yarn intake conduit, the yarn wetting apparatus comprising:
- a reservoir;
- a porous wetting body extending to the reservoir and having capillary capacity, the wetting body having a yarn passage opening which tapers inwardly in the direction of yarn travel to an inner end which is spaced above the yarn intake conduit relative to the direction of yarn travel;
- and
- at least one wetting agent back flow channel that communicates the inner end of the yarn passage opening with the reservoir.
A two-for-one twisting spindle assembly having a spindle hollow axis and a yarn intake conduit comprising:
- a yarn wetting apparatus disposed at the upper end of the spindle hollow axis, the yarn wetting apparatus having a reservoir and a porous wetting body which extends into the reservoir and has capillary capacity, the wetting body having a yarn passage opening which tapers inwardly in the direction of the yarn intake conduit and in the direction of the spindle hollow axis to an inner end which is spaced above the yarn intake conduit relative to the direction of yarn travel;
- and
- at least one wetting agent back flow channel that communicates the inner end of the yarn passage opening with the reservoir.
