Abstract

A spinning preparation machine includes a consolidating means for producing a roving having a protective twist from a fiber bundle, a drafting system arranged upstream of the consolidating means, a winding device arranged downstream of the consolidating means, and a movably mounted traversing element adjacent the winding device to guide the roving being wound onto a tube. In a side view of the spinning preparation machine, the consolidating means is arranged vertically between at least one feed roller of the drafting system and the traversing element, and the feed roller and the traversing element are arranged on a same side of the consolidating means so that in operation of the spinning preparation machine, the roving experiences a change in direction after exiting the consolidating means and prior to being wound onto the tube.

First claim

The invention claimed is:

1. A spinning preparation machine, comprising:
a consolidating means for producing a roving having a protective twist from a fiber bundle supplied to the consolidating means;
a drafting system arranged upstream of the consolidating means in a running direction of the roving to draft the fiber bundle;
a winding device arranged downstream of the consolidating means in the running direction to wind the roving onto a tube;
a movably mounted traversing element adjacent the winding device to guide the roving being wound onto the tube;
in a side view of the spinning preparation machine, the consolidating means arranged vertically between at least one feed roller of the drafting system and the traversing element;
in the side view of the spinning preparation machine, the feed roller and the traversing element arranged on a same side of the consolidating means so that in operation of the spinning preparation machine, the roving experiences a change in direction after exiting the consolidating means and prior to being wound onto the tube; and
a tube transfer device disposed to transfer the tubes from a tube transport device to the winding device or from the winding device to the tube transport device, wherein the traversing element, in the side view, is arranged horizontally between the consolidating means and the tube transfer device.

2. The spinning preparation machine in accordance with claim 1 , wherein the consolidating means comprises an air spinning nozzle, and wherein the roving having the protective twist is produced inside the air spinning nozzle by means of a swirled air flow.

3. The spinning preparation machine in accordance with claim 1 , further comprising a pair of draw-off rollers arranged downstream of the consolidating means in the running direction, the pair of draw-off rollers arranged vertically between the feed roller of the drafting system and the traversing element, wherein the roving experiences the change of direction through or downstream of the pair of draw-off rollers.

4. The spinning preparation machine in accordance with claim 1 , wherein the winding device further comprises at least one tube receiver to fix the tube thereon, the tube receiver arranged, in the side view, horizontally between the tube transfer device and the traversing element, or between the tube transfer device and the consolidating means, or between the tube transfer device and the pair of draw-off rollers.

5. The spinning preparation machine in accordance with claim 4 , wherein one or both of the tube receiver or the tube transfer device are arranged, in the side view, below the consolidating means.

6. The spinning preparation machine in accordance with claim 4 , wherein the tube receiver, the traversing element, and the consolidating means are arranged, in the side view, below the tube transfer device.

7. The spinning preparation machine in accordance with claim 1 , further comprising a guide for the fiber bundle arranged upstream of the drafting system in a transport direction of the drafting system, the guide comprising a feed segment at an end thereof opposite from the drafting system and a delivery segment at an end thereof adjacent the drafting system, and the feed segment arranged, in the side view, on a side of the tube transfer device facing away from the consolidating means.

8. The spinning preparation machine in accordance with claim 7 , wherein the drafting system, the winding device, the tube transfer device, and the guide are arranged, in a front view of the spinning preparation machine, at least in part behind the consolidating means.

9. The spinning preparation machine in accordance with claim 1 , wherein the traversing element, the winding device, and the tube transfer device have at least one common horizontal sectional plane.

10. The spinning preparation machine in accordance with claim 9 , wherein the feed roller and the consolidating means have a common sectional plane that, in the side view, intersects the first horizontal sectional plane at a side of the consolidating means that faces away from the winding device.

11. The spinning preparation machine in accordance with claim 10 , wherein the common horizontal sectional plane and the common sectional plane form an angle (a) that ranges between 85° and 20°.
