Abstract
Fibre rovings are impregnated with liquid at the moment when they are wound on a drum 5 after carding, division and rubbing. The drum 5 comprises apertures 6. A conduit 8 leads liquid axially into the drum and nebulizers 9 disperse the liquid on the inside thereof. The drum 5 is covered on the outside with a layer of absorbent material to distribute the liquid. <IMAGE>
Description
SPECIFICATION
Impregnation of rovings of fibres
The invention relates to a process and a device for impregnating rovings or slivers of fibres after carding, division and rubbing. Such rovings are generally tubular, and may be of textile or other spinnable fibres or a mixture thereof.
According to the invention, the fibres are wet at the moment when they are wound on a drum. The wetting may be with demineralized water. Flows of liquid to the drum may be controlled by the pressure of the liquid or by the duration and frequency of pulses of that pressure. The wetting at this stage reduces the formation of dust which is advantageous when working with asbestos fibres.
The invention includes a device which comprises a drum on which the rovings are wound, the drum having apertures in its outer surface, and means for nebulizing a liquid inside the drum. Preferably the drum is covered with an absorbent material to distribute the liquid along the length of the drum. The nebulizers may be mounted on a conduit which extends parallel to the axis of the drum or actually along the axis of the drum. The conduit may be fixed or rotatable in the same or opposite sense with respect to the drum.
Drawings
Figures 1 and 1 a illustrate a previously known device for winding rovings on a drum in a side view and transverse section respectively; and
Figure 2 illustrates a device according to the invention.
In Figures 1, rubbed rovings from the brushing section of a continuous divider 1 pass as a narrow tubular band to a rove guide 2 on their way to a rove winding drum 3. On the drum 3, there is mounted a cylindrical rove rod 4 on which the rovings are wound by rotation of the drum 3. The guide 2 is moved to and fro parallel to the axis of the drum to build up the rovings in a grooved or fluted manner on the rod 4. A single or double row of drums may be used. Alternatively, the drum(s) themselves may be moved to and fro to provide a mobile winding. A package of rovings of predetermined thickness and diameter is thus built up regularly and continuously.
In Figure 2, a rove drum 5 for the build-up of wound rovings consists of a thin cylindrical skin pierced by aperture 6. At each end of the cylinder, there are plates 7 with an axle whereby the drum 5 can be mounted in bearings. The axle has a coaxial bore containing a conduit 8 for feeding
impregnation liquid. The conduit 8 extends inside the skin parallel to the axis of the cylinder and
carries nebulizers 9 for the liquid. Thus the conduit
8 comprises a supply rail for the liquid and disperses the liquid on the inside of the skin. The drum 5 is covered on the outside with a thin layer of absorbent material 10 (textile or felt) to distribute and regulate the flow of liquid along all the inside surface of the skin.
The winding increases in diameter with the rotation of the drum yet remains always in contact with the absorbent covering. The covering remains wet as it is continuously and regularly fed with liquid from the nebulizers inside. The regular distribution of the nebulized liquid is achieved by the regular spacing of the nebulizers 9 on the rail, their inclination to the drum, the diameter of the holes 6, the distance of the rail from the inside of the skin, and the shape of the jet of liquid projected. The quantity of liquid can be regulated according to the degree of impregnation desired by the amount of flow, the type of nebulizer, the pressure of the liquid the nebulization time, and the number of injection sequences.
1. A process of impregnating rovings of fibres in which after carding, division and rubbing, the fibres are wet at the moment when they are wound on a drum.
2. A process according to claim 1 in which the fibres are wet with demineralized water.
3. A process according to claim 1 or claim 2 in which a flow of liquid to the drum is controlled either by the pressure of the liquid or by the duration and frequency of pulses of that pressure.
4. A device for impregnating rovings of fibres after carding, division and rubbing which comprises a drum on which the rovings are wound, the drum having apertures in its outer surface, and means for nebulizing a liquid inside the drum.
5. A device according to claim 4 in which the drum is covered with an absorbent material to distribute the liquid along the length of the drum.
6. A device according to claim 4 or claim 5 in which nebulizers are mounted on a conduit which extends parallel to the axis of the drum.
7. A device according to claim 6 in which the conduit is fixed in relation to the drum.
8. A device according to claim 6 in which the conduit is rotatable with respect to the drum.
9. A device for impregnating rovings of fibres as herein described with reference to Figure 3 of the drawings.
